Abstract: Rainfall is the key factor to understand soil erosion processes, mechanisms, and rates. Most research was conducted to determine rainfall characteristics and their relationship with soil erosion (erosivity) but there is little information about how atmospheric patterns control soil losses, and this is important to enable sustainable environmental planning and risk prevention. We investigated the temporal and spatial variability of the relationships of rainfall, runoff, and sediment yield with atmospheric patterns (weather types, WTs) in the western Mediterranean basin. For this purpose, we analyzed a large database of rainfall events collected between 1985 and 2015 in 46 experimental plots and catchments with the aim to: (i) evaluate seasonal differences in the contribution of rainfall, runoff, and sediment yield produced by the WTs; and (ii) to analyze the seasonal efficiency of the different WTs (relation frequency and magnitude) related to rainfall, runoff, and sediment yield. The results indicate two different temporal patterns: the first weather type exhibits (during the cold period: autumn and winter) westerly flows that produce the highest rainfall, runoff, and sediment yield values throughout the territory; the second weather type exhibits easterly flows that predominate during the warm period (spring and summer) and it is located on the Mediterranean coast of the Iberian Peninsula. However, the cyclonic situations present high frequency throughout the whole year with a large influence extended around the western Mediterranean basin. Contrary, the anticyclonic situations, despite of its high frequency, do not contribute significantly to the total rainfall, runoff, and sediment (showing the lowest efficiency) because of atmospheric stability that currently characterize this atmospheric pattern. Our approach helps to better understand the relationship of WTs on the seasonal and spatial variability of rainfall, runoff and sediment yield with a regional scale ba

Abstract: Soil degradation by water is a serious environmental problem worldwide, with specific climatic factors being the major causes. We investigated the relationships between synoptic atmospheric patterns (i.e. weather types, WTs) and runoff, erosion and sediment yield throughout the Mediterranean basin by analyzing a large database of natural rainfall events at 68 research sites in 9 countries. Principal Component Analysis (PCA) was used to identify spatial relationships of the different WTs including three hydro-sedimentary variables: rainfall, runoff, and sediment yield (SY, used to refer to both soil erosion measured at plot scale and sediment yield registered at catchment scale). The results indicated 4 spatial classes of rainfall and runoff: (a) northern sites dependent on North (N) and North West (NW) flows; (b) eastern sites dependent on E and NE flows; (c) southern sites dependent on S and SE flows; and, finally, (d) western sites dependent on W and SW flows. Conversely, three spatial classes are identified for SY characterized by: (a) N and NE flows in northern sites (b) E flows in eastern sites, and (c) Wand SW flows in western sites. Most of the rainfall, runoff and SY occurred during a small number of daily events, and just a few WTs accounted for large percentages of the total. Our results confirm that characterization by WT improves understanding of the general conditions under which runoff and SY occur, and provides useful information for understanding the spatial variability of runoff, and SY throughout the Mediterranean basin. The approach used here could be useful to aid of the design of regional water management and soil conservation measures.

Abstract: Trabajo presentado en TERRAenVISION Environmental Issues Today: Scientific Solutions for Societal Issues, celebrado en Barcelona (España) del 27 de enero al 2 de febrero de 2018, This contribution results from international collaborative efforts of different research groups around the Mediterranean basin focusing on soil conservation and water management. We will present the most complete database of runoff and soil erosion information and analyze the records from 68 locations, including more than 22458 detail events between 1985-2015. Soil conservation and water planning are two of the most challenging problems around the Mediterranean basin due to climate conditions and human activity. We believe that future advances on understanding soil degradation by water should be developed under global approaches. In this contribution, we will present an analysis of atmospheric conditions, expressed by weather types and the resulted rainfall, runoff, and erosion and sediment yield around the Mediterranean basin. The weather types compile daily information about the different air masses responsible for rainfall, runoff and eventually erosion and sediment yield, and their analyses let us know the synchrony of the response at different sites around the Mediterranean basin. The analyses of the global dataset display different spatial patterns for rainfall, runoff, and sediment yield, related to different atmospheric patterns. This research will be a valuable tool for understanding the evolution of these environmental variables, and therefore it will allow future planning to design regional water management and soil conservation measures

Abstract: Increased soil erosion, pressure on agricultural land, and climate change highlight the need for new management methods to mitigate soil loss. Management strategies should utilize comparable data sets of long-term soil erosion monitoring across multiple environments. Adaptive soil erosion management in regions with intense precipitation requires an understanding of inter-annual variability in sediment yield (SY) at regional scales. Here, a novel approach is proposed for analysing regional SY. We aimed to (i) investigate factors controlling inter- and intra-annual SY, (ii) combine seasonality and time compression analyses to explore SY variability and (iii) discuss management implications for different Mediterranean environments. Continuous SY measurements totalling 104 years for eight small catchments were used to describe SY variability, which ranged from 0 to 271 t/ha/year and 0 to 116 t/ha/month. Maximum SY occurs in spring to summer for catchments with oceanic climates, while semi-arid or dry summer climates experience SY minimums. We identified three time compression patterns at each time scale. Time compression was most intense for catchments with minimum SY in spring to summer. Low time compression was linked to very high soil loss, low run-off and sediment production thresholds, and high connectivity. Reforestation, grassland and terracing changed SY magnitudes and time compression, but failed to reduce SY for large storm events. Periods with a high probability of high SY were identified using a combination of intra-annual SY variability, seasonality analysis, and time compression analysis. Focusing management practices on monthly flow events, which account for the majority of SY, will optimise returns in Mediterranean catchments.

10. Comparative analysis of major erosive events in a set of small Mediterranean research catchments

Abstract: Soil erosion is one of the environmental problems of main concern in Mediterranean areas because of significant both on- and off-site issues such as soil loss, land degradation, reservoir siltation, water quality and ecological impacts. Even if it has longly been observed that major erosive events are almost always associated to extremely large or intense rainfall events, little is known on the exact nature of these events at the small catchment scale. One of the main reasons for this is that, frequently, the investigation of variables influencing sediment yield is done through the analysis of erosive events of highly variable magnitude, with the objective of deriving general log-relationships between sediment yield and hydrological variables. With such approach, the specificity of the most erosive events is often lost in the analysis where large events act as a single cluster at one extreme of the events distribution and their real magnitude is masked by the log scale.With the objective of determining the specific characteristics of the most erosive events, and to infer some of the key processes acting during them, this study presents an analysis of the 10 most erosive events recorded for a set of 10 small research catchments located in the Mediterranean region. The different catchments, grouped in the R-OSMed Network, are located in France (4), Spain (3), Italy (1), Portugal (1) and Tunisia (1); the catchments have areas ranging from 0.018 to 1.32 km2, mean annual precipitation from 236 to 1303 mmyear-1 and mean annual sediment yield between 7.5 and 6900 Mgkm-2year-1. In total more than 120 years of hydrological and sediment data (series between 3 and 29 years long) have been analysed to select the 10 most erosive events for each catchment. The study is based on the analysis of the relationship existing between a series of meteorological, hydrological and sediment related variables. First results show that the cumulated sediment yield of these 10 most erosive events represented a variable proportion (from 150 to 1500%) of the mean annual suspended sediment yield. The size of the catchments, their relative area with intense erosion and the mean annual rainfall were identified as the main causes of the differences between the catchments responses. For major erosive events, runoff depth was more dependent on rainfall depth than on rainfall intensity, whereas peakflow was not clearly related to any specific variable. Suspended sediment load during major erosive events was most often related to runoff depth and to peakflow discharge, but considering all catchments, no general relationship could be observed between suspended sediment concentration (maximum and mean) and rainfall or runoff variables. Results also show that the return periods associated to rainfall and flood characteristics may be used as a measure of the singularity of the diverse variables, allowing a better characterisation of major erosive events. Finally, the comparison between the responses of the different catchments helps to improve the knowledge of the hydrological and geomorphological functioning of each of them.

12. Sectoral Agglomeration Economies in a Panel of European Regions

Subjects: employment density, productivity, european regions, dynamic panel GMM
Abstract: We estimate agglomeration economies, defined as the effect of density on labour productivity in European regions. The analysis of Ciccone (2002) is extended in two main ways. First, we use dynamic panel estimation techniques (system GMM), thus offering an alternative methodological treatment of the inherent endogeneity problem. Second, the sector dimension in the data allows for disaggregated estimation. Our results confirm the presence of significant agglomeration effects at the aggregate level, with an estimated long-run elasticity of 13 percent. Repeated crosssection regressions suggest that the strength of agglomeration effects has increased over time. At the sector level, the dominant pattern is of cross-sector "urbanisation" economies and own-sector congestion diseconomies. A notable exception is financial services, for which we find strong positive productivity effects from own-sector density.

Abstract: In the Southern French Alps, the black marls formation covers a large area and is highly susceptible to weathering and erosion. It has a badlands topography and is subject to high solid transport, bringing high sediment yield downstream and silting up reservoirs. The scale is decisive in the study of erosion processes and quantification of sediment production, de Vente and Poesen (2005). This paper focuses on erosion at the slope and gully spatial scale and at the event temporal scale and is based on the data collected since 1983 by cemagref on a small gully, called Roubine (1330 m²). For the 19852003 period, 1016 rainfall events were registered, 472 produced runoff at the outlet and 373 yielded measurable erosion. A total of 288 sediment trap measurements are available and 205 five floods were sampled for suspended sediment. For the 19 years of the study period, the 19 highest values represent 33% of the total production of the period. For the data of all the events, there was no relation between suspended sediment concentration and flow discharge, but for one event hysteresis curves were observed. The total amount of sediment trap deposit represents a mean 9 m3 per year, i.e. 10 kg y1 m2. The ratio of suspended sediment in the total yield was 15% on average, 20% in cumulated amount, but reached 5050% for a few events. The analysis conducted on 19 years of rainfall-runoff-erosion data and field observations allows us to propose an erosion production model at the gully scale in marly badlands catchments. A seasonal pattern was observed with the renewal of the weathered mantel in winter, substantial displacement of material with spring events, high production of numerous and intense summer storms, and a decrease in sediment availability in autumn.

Abstract: National audience; Cemagref (Agricultural and Environmental Engineering Research Center) in Grenoble and the Scientific Group "Draix, mountain erosion studies" held a conference in Digne, in the French Alps, from October 15 to 17, 2003, devoted to the theme of gully erosion in mountain areas. The aims of this international seminar were to evaluate the state of the art in research on erosion by water in uplands, to allow scientists to meet and exchange ideas on related topics, and to initiate further collaborations, with particular emphasis on field work in research basins. This meeting, which encompassed 32 oral presentations and 24 posters, was attended by 80 participants from 12 countries. A one-day scientific excursion to the Draix experimental site was dedicated to multidisciplinary researches on mountain erosion and upland floods. Gully erosion represents an important sediment source in river systems and accounts for as much as 70 to 90% of the overall sediment production of a catchment. In mountain areas, the steep slopes enhance gully processes, accelerate sediment transfer from uplands to valley bottoms and generate natural hazards: mudflows, overflowing of heavily loaded floods, silting up of reservoirs, for example. Therefore, there is a need for monitoring and for experimental and modelling studies in order to forecast the effects of climatic or land use changes on sediment dynamics in mountain catchments. In mountain environments, the development of appropriate measurement and observation techniques is quite difficult. Original devices were presented, operating from the small plot scale to the large gully and catchment scales. Several presentations focused on the processes and factors controlling erosion and gullying in mountain areas: these include mechanical breakdown and chemical weathering of rocks, bed load and suspension sediment transport, in which threshold effects have a determining influence. Mass movements are also a substantial source of sediments in steep upland basins. These may occur as superficial earth flows affecting the weathered layer, and as deep-seated landslides or rock-block slides. Several papers examined the susceptibility of the terrain to the mass movements, the conditions for landslide initiation, the relations between mass movements in black marls and rockfalls in the overlying limestone levels, and the formation and propagation of debris flows. The major role of a few paroxystic events in sediment production was pointed out by several authors. Particle detachment, mass movement initiation, and sediment transport are processes subjected to threshold effects. The connectivity in the basin network may vary from one event to the other. The studies on sediment load rates during floods showed that the availability and location of sediment stocks in the channel and gully bottoms play a greater role than the transport capacity of the flow. The role of the vegetation cover in diminishing sediment yields is widely accepted. Therefore, it is still necessary to understand how the aerial parts and roots of vegetation interact with runoff and erosion in order to model the evolution of gully systems subject to climatic or land use changes. These studies show that erosion modelling becomes more complex as one goes from the plot or slope scale to the catchment scale, which necessitates a transport-distance approach. At this scale, the question of connectivity between flow paths becomes crucial and depends on the time scale of the study. The present issue of the journal publishes five papers related to erosion measurement and remote sensing, to erosion dynamics at the catchment or at a regional scale, and interactions between erosion, and vegetation and restoration works. The paper by D. Raclot et al. presents a first attempt of at using low-altitude aerial photographs taken from a drone for erosion surveys in the Draix area. The relatively poor vertical accuracy (70 cm) does not allow yet for the measurement of short-term ablation, but the good quality and resolution of the pictures, and the possibility for of repeated acquisition offer good opportunities for the survey of landform evolution, especially in remote areas of the studied catchment. Two others additional papers (E. Gauché, J. Collinet & P. Zante) present fruitful methodologies for mapping and topographic survey of gully development. Recent progress in GIS and DEM techniques complete the quantitative observation of erosion processes. Addressing scale issues, the paper by J. Collinet and P. Zante presents different techniques in Tunisia covering rainfall simulation on plots in the flat upstream areas, monitoring of gully evolution on the intermediate slopes, sedimentation in reservoirs at the outlets. The authors show the importance of the processes linking these three slope interfaces. In Morocco, E. Gauché found contrasting rhythms of landscape evolution between mountain slopes and alluvial deposits downstream. Lithology and relief play a role, which is reinforced by land use change to a point that an erosion crisis may be identified, mainly due to the decrease of the extent of tilled areas. The paper by F. Rey presents an experimental bioengineering device for trapping sediments in gullies in marls of the French Alps and shows how brush layers 1.2 m thick across a gully may trap 0.1 to 0.3 m3 per year. The paper by M. Cohen and F. Rey discusses the paradox between positive vegetation dynamics at the regional scale and active erosion observed at the local scale and shows that processes vary depending on spatial scales: for instance, gully erosion may co-exist with vegetation spread on interfluves. Temporal and spatial scales as well as connectivity in soil erosion systems appear as key questions for further research on gully erosion, including appropriate measurement techniques, process analysis, modelling, and upscaling.

Abstract: International audience; The physically-based, distributed flow and sediment transport modelling system SHETRAN was applied to the Draix basins to test its ability to represent badlands flow and erosion response, to quantify characteristic parameter values and to investigate spatial scale effects in badlands modelling. A unit gully, area 0.133 ha, was simulated using a 5-m grid resolution model and a single cell model, with comparable results. Application of the modes to a badlands basin, area 86 ha, suggests that transfer of parameter sets from the gully scale to a larger scale may be feasible but, given uncertainty in parameter evaluation, a separate calibration still yields improved results. Considering the flashy basin responses, satisfactory flow simulations were achieved using physically realistic parameter values, and sediment yields were well simulated within the bounds of uncertainty. Any scale effects which may distinguish the gully and basin simulations are masked by the uncertainty in parameter evaluation.

Abstract: Este artículo contiene 16 páginas, 6 figuras, 2 tablas., Soil degradation by water is a serious environmental problem worldwide, with specific climatic factors being the major causes. We investigated the relationships between synoptic atmospheric patterns (i.e. weather types, WTs) and runoff, erosion and sediment yield throughout the Mediterranean basin by analyzing a large database of natural rainfall events at 68 research sites in 9 countries. Principal Component Analysis (PCA) was used to identify spatial relationships of the different WTs including three hydro-sedimentary variables: rainfall, runoff, and sediment yield (SY, used to refer to both soil erosion measured at plot scale and sediment yield registered at catchment scale). The results indicated 4 spatial classes of rainfall and runoff: (a) northern sites dependent on North (N) and North West (NW) flows; (b) eastern sites dependent on E and NE flows; (c) southern sites dependent on S and SE flows; and, finally, (d) western sites dependent on W and SW flows. Conversely, three spatial classes are identified for SY characterized by: (a) N and NE flows in northern sites (b) E flows in eastern sites, and (c) Wand SW flows in western sites. Most of the rainfall, runoff and SY occurred during a small number of daily events, and just a few WTs accounted for large percentages of the total. Our results confirm that characterization by WT improves understanding of the general conditions under which runoff and SY occur, and provides useful information for understanding the spatial variability of runoff, and SY throughout the Mediterranean basin. The approach used here could be useful to aid of the design of regional water management and soil conservation measures., This research was supported by projects funded by the MINECOFEDER: CGL2014-52135-C3-3-R, CGL2014-59946-R, CGL2015-65569- R, CGL2015-64284-C2-2-R, and PCIN-2017-061/AEI.

Damià Vericat is now a Serra Húnter Fellow at the University of Lleida. María Fernández-Raga received a “José Castillejo” postdoctoral grant (Spanish Ministry of Education, Culture and Sports). Carla Ferreira was supported by a post-doctoral research grant from the Portuguese Science and Technology Foundation (SFRH/ BPD/120093/2016). Mariano Moreno-de las Heras received a Juan de la Cierva postdoctoral contract (IJCI-2015-26463) from the MEC. José Andrés López-Tarazón received a Vicenç Mut postdoctoral fellowship from the Autonomous Balearic Government (CAIB PD/038/2016).

Abstract: Producción Científica, Rainfall is the key factor to understand soil erosion processes, mechanisms, and rates. Most research was conducted to determine rainfall characteristics and their relationship with soil erosion (erosivity) but there is little information about how atmospheric patterns control soil losses, and this is important to enable sustainable environmental planning and risk prevention. We investigated the temporal and spatial variability of the relationships of rainfall, runoff, and sediment yield with atmospheric patterns (weather types, WTs) in the western Mediterranean basin. For this purpose, we analyzed a large database of rainfall events collected between 1985 and 2015 in 46 experimental plots and catchments with the aim to: (i) evaluate seasonal differences in the contribution of rainfall, runoff, and sediment yield produced by the WTs; and (ii) to analyze the seasonal efficiency of the different WTs (relation frequency and magnitude) related to rainfall, runoff, and sediment yield. The results indicate two different temporal patterns: the first weather type exhibits (during the cold period: autumn and winter) westerly flows that produce the highest rainfall, runoff, and sediment yield values throughout the territory; the second weather type exhibits easterly flows that predominate during the warm period (spring and summer) and it is located on the Mediterranean coast of the Iberian Peninsula. However, the cyclonic situations present high frequency throughout the whole year with a large influence extended around the western Mediterranean basin. Contrary, the anticyclonic situations, despite of its high frequency, do not contribute significantly to the total rainfall, runoff, and sediment (showing the lowest efficiency) because of atmospheric stability that currently characterize this atmospheric pattern. Our approach helps to better understand the relationship of WTs on the seasonal and spatial variability of rainfall, runoff and sediment yield with a regional scale based on the large dataset and number of soil erosion experimental stations., Ministerio de Economía y Competitividad - FEDER (CGL2014 52135-C3-3-R; ESP2017-89463-C3-3-R; CGL2014-59946-R; CGL2015-65569-R; CGL2015-64284- C2-2-R; CGL2015-64284-C2-1-R; CGL2016-78075-P; GL2008-02879/BTE; LEDDRA 243857; RECARE-FP7; CGL2017-83866-C3-1-R y PCIN-2017- 061/AEI), Ministerio de Economía y Competitividad (FJCI-2017-33652), Organización para la Cooperación y el Desarrollo Económicos (TAD/CRP JA00088807), Junta de Castilla y León - FEDER (CLU-2018-04)

Abstract: In 186 patients with early colon cancer, we investigated the assumption that the meaning of 'quality of life' (QL) remains constant over time. Within a phase-III trial (SAKK 40/93), patients estimated both their overall QL and a range of disease- and treatment-related domains at five timepoints, comprising three concurrent and 2 retrospective estimates: their pre-surgery QL both before surgery and retrospectively thereafter, and their pre-adjuvant QL both at the beginning of adjuvant treatment and retrospectively about 2 months later, and their current QL 2 weeks thereafter. Multilevel models were developed to determine whether the selected domains made stable contributions to overall QL at the concurrent estimates. The weights of the domains changed over time. They did not differ significantly according to whether patients were considering their concurrent state or reflecting on this state at a later timepoint. In the process of adaptation, patients with early colon cancer substantially change the relative importance of QL domains to overall QL. This finding argues for QL as a changing construct and against the assumption that domain-specific weights are stable across distinct clinical phases.
