The bachelor thesis deals with the assessment of significant geomorphological sites around the rocky hill of Babí lom in the Adamovská vrchovina Highland north of Brno. Within the area of interest, ten geomorphological sites are identified and described in detail. The methodology of geomorphosites is used for their assessment. The selected sites include not only individual parts of the distinctive ridge of Babí lom, but also, for example, forest springs or boulder streams, the geomorphological significance of which is currently not fully appreciated. An important aim of this thesis is to remind these overlooked localities and point out both their values and their vulnerability. Based on the assessment of individual sites, the entire area of interest is then assessed in summary and improvements in its use, management and protection are proposed.

Hazard evaluation from GLOFs in the Cordillera Huayhuash Abstract: Proglacial lakes in high-mountain regions recently experienced dynamic development related to the ongoing climatic changes. Most of the mountain ranges were widely studied with respect to hazards posed by proglacial lakes. However, the Peruvian Cordillera Huayhuash was omitted by any research of this type so far. In this thesis first, the author develops and assesses the inventory of glacial lakes in the Cordillera Huayhuash, and second, evaluates the hazard from GLOFs. After a thorough discussion and comparison to other world's major mountain ranges, significant conclusions are made. Most of the characteristics of the lakes in the Cordillera Huayhuash are influenced by a local factor - fluvial erosion that has occurred since the last glacial maximum. Nevertheless, general principles such as the statistical distribution of lakes according to their elevation that are valid to other compared regions may still be identified based on the data. Lakes of the Cordillera Huayhuash generally pose minor or even no GLOF hazard, the few exceptions were further analyzed in detail. Key words: geomorphology, GLOF, lake inventory, natural hazards, Peru

The study deals with analysis of of geomorphological pronunciation of neotectonics along the based on fault slope in the South American Cordillera Blanca range. It contains research about physical-geographycal characteristic of the mountain range with the focus on geology, geomorphology and the theoretical concept of forms on fault slopes and neotectonic acitivity. In the practical part of the thesis, the selected area of the mountain range was mapped using Google Earth imagery. On the base of created map the forms associated with the active tectonic uplift of the Cordillera Blanca were analyzed and invented. Then the longitudinal profiles of rivers that flow across the fault zone were created and analyzed from the digital terrain model. The block structure of the mountain range was analyzed too.

Lichenometry is a constantly developing method (or set of methods) of relative and absolute dating of geological and anthropogenic formations, based on analysis of crustose lichens. It operates with an assumption that the larger the thallus is, the older the lichen is. But the relation between size and age (known as "growth rate") is far from being linear, and lichenometry has long attempted to find a way of describing this relation properly and universally. For this purpose, lichenometry uses direct and indirect methods - by repeated measurements of the same lichen individuals over time, or by comparison to individuals growing on substrates of known age (e.g. by using radiocarbon method). There is an ongoing controversy about aging and age calibration since the inception of the lichenometry field, but especially in this century. Strong criticism has been expressed about lichenometry, questioning the very principles of the method and consequently undermining all the results of lichenometry so far. The goal of the present bachelor thesis is to present the method with its approaches and to address the criticism. At the same time I aim to highlight recent trends in the field that seek to improve the methods toward more reliable lichenometric dating, and to encourage the use of the methods as so...

Coastal dunes occur along the sandy shores of most continents where they serve as coastal defence against flooding, provide areas for recreation, store drinking water and harbour unique biodiversity. Coastal dunes and the services they provide are threatened by climate-induced sea-level rise. This threat may be mitigated by the spontaneous formation of new dunes, for example in combination with mega-nourishments aimed at increasing beach width. Coastal dunes form by the interaction between vegetation, wind and wave action. Persistent dune development begins with the establishment of vegetation on the beach: the vegetation traps the wind-blown sand, forming an embryo dune. Over time an embryo dune can develop into a bigger foredune, increasing coastal safety. The formation and development of embryo dunes into foredunes depend on the vegetation establishment on the beach, dune growth over summer and dune erosion during winter. Although vegetation succession and geomorphological processes are each well described, the interaction between ecological and geomorphological processes during embryo dune development are not well known. The thesis aimed at further exploring these interactions, using a combination of experiments and high-resolution dune monitoring to study the mechanisms underlying early dune development and their implications for mega-nourishment design. To explore whether soil salinity, salt spray or storms determine the vegetation limit of dune building plant species on the beach, we performed a field transplantation experiment and a glasshouse experiment with two dune building grasses Ammophila arenaria and Elytrigia juncea. In the field growth of grasses transplanted into four vegetation zones from sea to dune was monitored for over a year and the response of these species to salt spray and soil salinity was tested in a glasshouse experiment. In the field, the vegetation zones were associated with differences in summer soil salinity: zones with both species present were significantly less saline than zones with only E. juncea or the zones without any vegetation. However, in our experiments the transplanted A. arenaria performed equal or better than E. juncea in all vegetation zones, suggesting soil salinity did not limit species performance at the studied site. Both species showed severe winter mortality. In the glasshouse experiment, A. arenaria biomass decreased linearly with soil salinity, presumably as a result of osmotic stress. Elytrigia juncea showed a nonlinear response to soil salinity with an optimum at 0.75% soil salinity and a decrease in biomass at higher salt concentrations. Our findings suggest that soil salinity stress either takes place in winter during storm inundation, or that development of vegetated dunes is less sensitive to soil salinity than hitherto expected. To understand the boundary conditions for embryo dune development over a longer time period we explored the effects of beach morphology, meteorological conditions and sand nourishment on early dune development using a 30 year time series of aerial photographs and beach profile monitoring data. We concluded that 1) beach morphology is highly influential in determining the potential for new dune development, with wide beaches enabling development of larger embryo dune fields, 2) sand nourishments stimulate early dune development by increasing beach width, and 3) weather conditions and non-interrupted sequences of years without high-intensity storms determine whether progressive dune development will take place. Dune development is the result of the interaction between vegetation development and sedimentation and erosion processes. To disentangle the effects of vegetation characteristics and that of dune size we monitored a natural dune field of 8 hectares for one year using an Unmanned Aerial Vehicle (UAV) with a camera. By constructing a digital surface model and a geometrical corrected image (an orthomosaic) for each flight campaign we calculated changes in dune volume over summer and winter and related these changes to vegetation, dune size and degree of shelter. The dune growth over summer was mainly determined by dune size, whereas dune growth over winter was determined by vegetation characteristics. Degree of shelter determined whether dune growth was limited by storm erosion (exposed dunes) or sand supply (sheltered dunes). These results suggest that vegetation characteristic may be particularly important for resisting storm erosion and speeding up recovery after erosion. Embryo dunes have been hypothesised to facilitate development of species rich green beach vegetation in the sheltered location between the embryo dunes and the primary foredunes. To test this hypothesis we explored the relative impacts of abiotic soil conditions as affected by the geomorphological setting on the species richness and species turn-over of green beach vegetation. To this end we characterised the geomorphology and measured abiotic conditions and species composition of green beach vegetation along transects from beach to foredune. We found that the geomorphological setting influenced plant species composition indirectly by affecting soil salinity and rate of sand burial. We found that plant species richness declined less at sheltered conditions, where there was a build-up of organic matter and no sand burial. Our results further suggest a non-linear relationship between embryo dune volume and number of green beach species: embryo dunes can be a source of shelter, thus stimulating green beach development, but can also compete for space, reducing green beach development. The net effect of embryo dunes most likely depends on the sediment budget of the beach and storm intensity. Mega-nourishments are single large sand nourishments that are applied locally, and are expected to exist for about 20 years, providing opportunities for the development of embryo dunes and rare pioneer plant communities (green beach vegetation). We explored this potential by comparing growth and development of dune building species on natural beaches with the results of plant transplantation and monitoring data of two mega-nourishments: the low-elevated Hondsbossche Duinen and the high-elevated Sandmotor. Our results suggest that establishment of dune building species on high-elevated mega-nourishment proceed slower than on natural beaches due to dispersal limitation. Once vegetation has established however, embryo dune development on high-elevated mega-nourishments may proceed faster than natural beaches due to low salinity and protection against storm erosion. Development of dune-building vegetation on the low-elevated mega-nourishment Hondsbossche Duinen showed the same rate and pattern as that on a natural beach. The potential for embryo dune development on mega-nourishments is far bigger than the potential for green beach development, since green beach vegetation develops under a narrower range of abiotic conditions. Such abiotic conditions can develop behind the shelter of embryo dunes or foredunes at low beach elevations. In conclusion this thesis shows that, 1) the potential of embryo dune development depends on a large beach width and low storm erosion which determines the vegetation limit. 2) Embryo dune growth over summer is mainly determined by existing dune volume and sand supply. 3) Heavy storms limit embryo dune development during winter, although dune erosion can be mitigated by vegetation composition. 4) On accreting beaches which continuously provide area for the development of new embryo dunes green beach vegetation can develop. 5) The design of a mega-nourishment determines the potential for the development of embryo dunes and green beach vegetation. Our findings provide insights in the interaction between ecological and geomorphological processes that determine embryo dune development. This knowledge can help to obtain better predictions of embryo dune development under the threat of sea-level rise.

Morphostructural analysis of Ethiopian Highland based on remote sensing The morphometric analysis of lineaments, valleys and signs of erosion taken from a digital elevation model (DEM) made it possible to not only confirm most of the conclusions of the morphotectonic development of the area from the previously published results of structural, petrological, tectonic and geochronological analyses from the Ethiopian Highlands, but to also to expand our knowledge by applying several new hypotheses. Faults, lineaments and valleys are predominantly oriented in a direction compatible to the published concepts of the tectonic development of the area. Overall, the most abundant NE-SW and NNE-SSW lines reflect a change of extension from a NW-SE to WNW-ESE direction during the Pliocene (~40ř rotation), in relation to the creation and development of the Main Ethiopian Rift. The most pronounced morphological manifestations of the extension of the MER and western Afar during the Quaternary are confined to the borders of the MER, and the maximum SOLR values indicate a very short-lived effect of the stress field on the development of the landscape. The directions of the Pre-Neogene rift structures to the NW-SE and WNW-ESE are compatible with the oldest elements of the current landscape, i.e. the most developed...

The subject of the diploma thesis is the change in the spatial distribution of erosion and sediment deposition landforms within the channel of four different-size rivers, and is based on the morphology of the river channel and presence of barriers. The objective of this thesis was to 1) map the spatial distribution of channel bars and locations of bank scour, 2) define the morphologic characteristics including the position with respect to the location of bends and obstructions in the channel of the individual river reaches, and 3) define common patterns, and explain potential differences between the patterns in the rivers of different size. For the purpose of this study a field reconnaissance was carried out on selected reaches of Sazava River, Litavka River, Kocaba River and Lodenice River. The selected sections represent relatively natural parts of river channels with similar geomorphic conditions. The field survey was carried out in two campaigns - in spring and in summer 2015. The results of the survey indicate that channel bends do not play a primary role in the position and morphology of channel bars and locations of bank scour. However, significant sediment deposition or erosion activity was identified near run-of-river dams. In the surveyed reaches of the Sazava and Litavka rivers, channel...

The master thesis is focused on analysis of the zone of recent deglaciation in the Cordillera Blanca, Peru. Geomorphological mapping that had been realized based on interpretation of the satellite data and field reconnaissance was used for interpretation of main geomorphological features and processes of the selected glacial valleys. Glaciofluvial processes and mass movements are the main processes that affected the relief in the recent period. Major differences in landforms presence and distribution have been found between the studied valleys. The main differences are between valleys located on the western side and eastern side of the mountains. Number of different sediments of different types have been identified on the western side, whereas no evidence of such sediments was found on the eastern side. These differences are probably caused by differences in geology and climatic conditions. Finally, a general sediment flux model on the information gained from the geomorfologic analysis has been created and shows space distribution of geomorphological features and processes. The analyses of the satellite data show different visual characteristics of the rocks, which has been confirmed during field works using Schmidt Hammer method. The results suggest that the rocks that have been exposed for longer time due...

Ancient Greece in the 7th century BC was important for the creation of philosophy and development of science. Although geomorphology didn't exist as an independent science in this time, there were the first attempts to explain and describe geomorphologic processes and landforms. The goal of this bachelor thesis is to aggregate descriptions and explanations of these phenomena from works of ancient Greek and Roman philosophers, historians and other authors. The main purpose is to point out correct explanations and to explain the cause of these which are wrong. Main phenomena, which were scholars focused on, were earthquakes, volcanism and the annual flood on the Nile River. Greeks and Romans believed that the Earth's relief is changing all the time. Relief landforms were used during campaigns, in agriculture and for the foundation of cities. The scholars were able to critically analyse theories of their ancestors. Despite the fact that some of the explanations were different from these of today, it shows us that science in ancient Greece and Rome is an important period for development of geomorphology and science in general. Key words: geomorphology, ancient Greece and Rome, Mediterranean

Area of interest of this bachelor thesis is part of Chilean Patagonia. It is spread through the Chilean regions of Los Lagos, Aysén and Magallanes. The local landscape consists of crystal blue lakes, glaciers, fjords and snow-capped mountains. Creating this landscape is involved in many endogenous and exogenous geomorphological processes. These processes take place on earth for millions of years, some of them, become to be risky when people began settling in this territory. Among these risk geomorphological processes in the countries of interest include earthquake, tsunami, volcanic activity, landslides and Glacial Lake Outburst Flood. The bachelor thesis also contains a chapter on remote sensing and its possible application in the prevention of risk processes or monitoring. The bachelor thesis is closed by a chapter with author's own assessment of these processes. The methodology of work is based on a review of foreign literature. Keywords: risk geomorphological processes, Patagonia, earthquake, tsunami, volcanism, landslides, GLOF, Remote Sensing

De ijstijden en zeker de laatste ijstijd hebben de basis gelegd voor ons 'oerlandschap'. Sedimentatie en erosie hebben het landschap verder vormgegeven. Afhankelijk van abiotische factoren als bodem en grondwater heeft de mens zich gevestigd en het landschap zodanig aangepast dat het optimaal kon worden benut voor het beoogde doel. Bij de ontginning ervan werden meestal de contouren gevolgd van het oorspronkelijke landschap. Ondanks vele ingrepen, die door de eeuwen heen hebben plaatsgevonden, zijn deze contouren nog steeds te zien.

Eén van de meest karakteristieke landschappen van de Noord-Europese Laagvlakte is de zogenaamde 'European sand belt', een gordel van windafzettingen die zich uitstrekt van Engeland tot aan de Oeral. Het zijn fijne zanden met een uniforme korrelgrootte: de dekzanden en rivierduinen van de laatste ijstijd, en de veel jongere windvormingen in de vorm van stuifzanfen van prehistorie en Middeleeuwen. Nederland draagt voor deze vormen een internationale verantwoordelijkheid. Helaas is er momenteel niemand in Nederland die zich hierom wetenschappelijk bekommert.

The morphodynamics of the lower River Vecht, the Netherlands, and the influence of geomorphological setting and bank composition on meandermigration were studied by means of reconstructing the pre-channelization landform configuration on a scale of 1 : 25,000, using historical mapsfrom 1720, 1850 and 1890 A.D. and other data.A downstream sequence of reaches was observed, each with a typical fluvial style and channel migration rate: (a) a narrow meander belt anda highly sinuous channel with intermediate migration rate, in the middle of an extensive floodbasin; (b) a wide meander belt and high rates oflateral channel migration, especially where large meanders impinged upon valley bluffs, as part of an incised setting; (c) a low sinuosity,embanked channel with low rates of downstream migration because of confinement by dikes, occurring in an inland delta with sandy sediments.Local variation in meander migration rates was observed within reach B. This was caused by the spatial variability of bank resistance asreflected by the width-depth ratio of the channel and the silt-clay ratios of deposits. River banks are: 1) very erodible when consisting of channeldeposits, aeolian dune deposits or when coarse fluvio-periglacial deposits occur at their base; 2) erodible when dominated by overbank depositsor aeolian sand sheet deposits; 3) resistant when a plaggen-layer is exposed; and 4) very resistant when dominated by floodbasin deposits.These implications of meander variability enable to assess the effects of the rehabilitation of the meandering process.

The Méma is a semi-arid region in central Mali with a rich archaeological heritage indicating the former existence of large urban settlements. The archaeological data suggest millennia of occupation history of the Méma preceding relatively sudden abandonment by the 14th or 15th century AD. Population numbers have remained low since then and today's human presence in the area is sparse and largely mobile. Geomorphologically, the Méma can be characterized as a graben hosting various generations of aeolian landforms and (presently mostly dry) interdunal channels and lakes, linked to the neighbouring Inland Niger Delta floodplain. Given this setting, and the variability of the Sahelian climate, climatic contributions to the region's sudden abandonment are likely. A geomorphological survey of the region, and interpretation of the observed geomorphological record in terms of climatic history, aimed at providing a basis for understanding the intensive occupation and subsequent abandonment of the Méma. The results of this study underscore dramatic Holocene climatic variability, leading to the region's present geomorphological diversity, but also suggest that neotectonic movements constitute an important additional cause of regional desiccation. Both may have encouraged prehistoric people to abandon the Méma after a long period of occupation.

dendrogeomorphological approach is presented, using wood characteristics of native oak (Quercus robur L.) to infer dynamics of aeolian sediment transport in drift-sand areas. Wood samples, taken from oaks in two drift-sand areas, were analysed to study changes in tree-ring pattern and wood anatomy as a consequence of burying or exposure from drift sand. In all cases, the wood of the sampled oaks showed sudden changes in anatomy and tree-ring width due to burial by drift sand or subsequent exposure after erosion of the new soil surface. After aerial stems became covered by drift sand, the wood lost its characteristic ring-porous features, and tree rings became strongly reduced in width with less distinct ring boundaries. Buried stems that became exposed after erosion showed an abrupt increase in ring width and turned distinctly ring porous again. Roots that were exposed also adopted clear ring-porous features, increased in ring width and anatomically resembled aerial stem wood. Using tree-ring analysis, it is possible to precisely date sand deposition and erosion events by detecting the concurrent changes in anatomy of woody structures. This study indicates the high potential of dendrogeomorphology as a tool to study drift-sand dynamics with a high temporal, i.e. annual, resolution for a period going back as long as the maximum age of the trees present (in this study at least 250 years). Since the signals of past deposition and erosion events are conserved in the wood, this is the only method that can be used to reconstruct drift-sand dynamics when the actual landforms are no longer present.

Ethiopia like other developing countries depends on domestic agricultural production, struggling with infrastructure and healthcare is also at a low level. Among these factors there is also added impact of catastrophic natural processes. Landslides in this area have caused enormous material damage and also human deaths. Effects of those losses are huge and locals are dealing with them difficuly. Therefore, prevention should be a priority concern. In theoretical part the basic facts about modeling and simulation of landslides susceptibility is presented. Those facts are complemented with specific researches from Ethiopian highlands. Furthermore, it describes the methodology that was used. It compares the real distribution of slope movements against the expected occurrence across the classes of input layers. An essential part of the model is mapping work, supported with terrain work, during which 242 landslides was mapped. Model parameters are: slope, altitude, lithology, land cover, distance from geological boundary and distance to river. Slope was determined as most significant factor. Used methodology is universally applicable and the results it generates match reality well. Key words: slope movements, natural hazards, susceptibility analysis, geomorphology, Ethiopian Highland

Atlantic grey seals (Halichoerus grypus grypus) started recolonising Dutch coastal haul-outs in the 1950s, after practically 500 years of rarity in the Dutch coastal zone which was caused mainly by human hunting. The first pup-birth was recorded in 1985 at the Wadden Sea sandbank of Engelschhoek. Sandbanks in the Wadden Sea may form and recede in periods of decades, but may change abruptly as a result of a single storm. These rapidly evolving places are not the perfect breeding habitat for grey seals, which exhibit long-term fidelity to breeding sites and only reluctantly shift. Little is known of the geomorphology of the currently utilised pupping sites, nor the implications of change in structure on future occupation and selection of new sites.

Impact events and associated processes can significantly reshape the natural environment of the Earth and other bodies in the Solar system. The Siljan impact crater in the middle of Sweden was created in late Devonian and it is the biggest known morphostructure of this kind in Europe. The presented paper aims at the relief evolution of the Siljan impact crater area. Landforms of the region are studied, including relicts of the impact event, and main stages of relief evolution from the Paleozoic to the present are determined. Special attention is focused to discussion about the range and types of erosional and denudational processes in relation to the level of preservation of morphological and geological indices about the Devonian impact. Ascertained knowledge about relicts of the Siljan impact event are compared with selected impact craters on the Earth, the Moon and Mars.

Een groot deel van onze beken heeft op dit moment een verre van natuurlijk verloop. Om wateroverlast tegen te gaan zijn in de vorige eeuw veel van oudsher kronkelige beken rechtgetrokken. Rechte beken voeren het water sneller af. Maar tegenwoordig is dat niet meer gewenst. Die snelle afvoer leidt tot verdroging en rechtgetrokken beken bieden weinig kansen voor een diversiteit in flora en fauna. Met beekherstel probeert men dat tij te keren. Bart Makaske en Gilbert Maas van Alterra schreven een boek over hoe je beken het beste laat kronkelen.

The use of optical scanning methods in geomorpho-analysis Abstract Main goal of this thesis is to find out if it is possible to use Structure from motion (SfM) method for analyzing geomorphological objects. Four geomorphological features in three different places within Pilsen-North region was used for testing this method. These objects with very dissimilar dimensions and shapes was scanned for this testing in various light conditions. All used data-sets was entirely created by author of this thesis. The data was initially processed by Agisoft Photoscan Professional Ediditon v1.1.6 and VisualSFM v0.5.26 to create spatial models. These models was afterwards processed in CloudCompare v2.6.1 and MeshLab v1.3.3. This software was used for clipping and merging of 3D models and for converting 3D models in to real dimensions. These real sized spatial models was then contrasted together by creating comparing entities. Outcomes are evaluated in the thesis conclusion. Keywords: Structure from motion (SfM), SIFT, RANSAC

De kaart wordt gebruikt voor de projecten Verwachtingen in lagen en Best practices prospectie van de RCE.

Methodological approaches to worksheets designed for field teaching of geomorpholog​y Abstract The purpose of this work was to determine whether there are rules and relations when it comes to the methodological approaches to worksheets created for fieldwork in natural sciences. Another object was to analyze the potential of Prague for geomorphological fieldwork. 101 worksheets from natural sciences were analyzed ​​in various categories, based on the research of literature. The data was processed even further with the use of statistics. Interesting geomorphological sights in Prague and their potential for fieldwork were defined after the research of scientific literature. The analysis has shown that those not designed for the use during fieldwork were more diverse than those designed for the use during fieldwork. Worksheets used during fieldwork were found to be more homogenic from the perspective of length, number of questions and the participation of components used in the worksheet. Several locations suitable for geomorphological...

The occurrence of avalanche paths is usually frequent in alpine environment, but it is also present in mid-mountains such as the High Sudetes. The submitted master thesis is focused on avalanche paths in the Eastern High Sudetes. The morphometric analysis of 8 paths was accomplished to determine their characteristics and comparison with statistical verification. The dendrogeomorphological analysis and further geomorphological mapping was performed in 2 selected paths (Sněžná kotlina and Králický Sněžník) to cover their avalanche activity frequency and to find relationship between their activity and morphology. The results of this study show that there is a strong difference between two groups of avalanche paths in the Eastern High Sudetes. The Sněžná kotlina and The Králický Sněžník avalanche paths are longer and narrower than the other paths. They also have higher elevation difference. The comparison of these two paths performed by dendrogeomorphology indicates higher avalanche activity frequency in the Sněžná kotlina path, which was strengthened after strong avalanche event in 2004. It is assumed that the Sněžná kotlina path contains advanced avalanche landform, which is a long gully, probably also affected by debris- flows in the past. On the other hand the Králický Sněžník path is rather less...

Zandverstuivingen worden doorgaans toegeschreven aan lokale menselijke ingrepen in het landschap, zoals afplaggen van de heide of de aanleg van zandwegen. Een nieuw hulpmiddel bij het karteren - het met behulp van laser-altimetrie opgebouwde Actueel Hoogtebestand Nederland (AHN) - laat echter zien dat de grote zandverstuivingen van de Midden-Veluwe geomorfologische ontwikkelingen zijn van een schaal die uitgaat boven lokaal menselijk ingrijpen

Erosie en depositie worden in hoge mate bepaald door enkele (heftige) regenbuien, zeker in Mediterrane semi-aride gebieden zoals Spanje. In landschapsevolutie spelen dezelfde processen een belangrijke rol, maar kijken we naar de effecten van die processen over duizenden jaren, bijvoorbeeld de vorming van rivier terrassen. Er zit een groot gat in tijdschaal tussen de regenbuien enerzijds (uren-dagen) en landschapsevolutie anderzijds. Hebben enkele (heftige) regenbuien nog invloed op landschapsevolutie en zo ja, op welke manier? Of is het cumulatieve effect van het grotere aantal kleinere buien uiteindelijk meer bepalend voor hoe het landschap zich ontwikkeld? De afgelopen 5 jaar heb ik me tijdens promotie-onderzoek bezig gehouden met dit thema. Het resultaat, mijn proefschrift, heb ik afgelopen 9 mei succesvol verdedigd aan de Wageningen Universiteit. Een overzicht van mijn onderzoek en de belangrijkste resultaten: 5 jaar in 3 pagina's!

Disturbances and patch dynamics are inherent to many ecosystems of the world, especially in the riparian zone. This paper describes the influence of natural levee overbank deposition on riverine grasslands along the meandering River Dinkel (the Netherlands). Here, the rare vegetation type Diantho-Armerietum, characterised by Dianthus deltoides, Thymus pulegioides, Pimpinella saxifraga and Galium verum, has been identified as important to nature conservation. Diantho-Armerietum shows a strong preference for dry, nutrient poor, sandy and relatively young soils, with an elevation approximately 30-50 cm above bankfull discharge level, corresponding to a flooding frequency of 2-3 times per year. The lower zones are strongly influenced by nutrient-rich water, whereas the higher zones are vulnerable to soil acidification. In the intermediate zone, soil development may be reset due to the supply of calcium, adsorbed to recently deposited levee sands. Since deposition rates will decrease with increasing levee heights, new levees are regularly needed to stop the decline of this floriferous vegetation type. The formation of new natural levees is favoured by the occurrence of meander cutoffs, causing a cyclic succession of landforms along the river. Thereforea conservation strategy for this vegetation type needs to aim at the rehabilitation of the natural levee disturbance process, in conjunction with encouraging the meandering of the river.

Stroomdalgrasland was vóór 1960 algemeen, is sindsdien dramatisch achteruitgegaan en is vrijwel verdwenen. Na Plan Ooievaar en de invoering van het wildernisbeheer is langs de grote rivieren veel veranderd. De nadruk kwam in veel terreinen te liggen op 'vergroting van de dynamiek' en 'spontane begrazing'. Wat betekent dit voor stroomdalgrasland en wat is hiervoor het optimale beheer?
