Abstract

International audience; 12 This article proposes an innovative approach to assess the benefits of adapting to sea level rise (SLR) in a coastal 13 area on a regional scale. The valuation framework integrates coastal ecosystem services, together with urban and 14 agricultural assets. We simulate the impacts of a progressive 1 m rise in sea level in the 21 st century and an extreme 15 flooding event in 2100 for four contrasted adaptation scenarios (Denial, " Laissez-faire " , Protection and Retreat). 16 The assessment involves coupling the results of hazard-modelling approaches with different economic valuation 17 methods, including direct damage functions and methods used in environmental economics. The framework is 18 applied to the French Mediterranean sandy coastline. SLR will result in major land-use changes at the 2100 time 19 horizon: relocation or densification of urban areas, loss of agricultural land, increase in lagoon areas and 20 modification of wetlands (losses, migration or extension of ecosystems). Total benefits of public adaptation options 21 planned in advance could reach €31.2 billion for the period 2010-2100, i.e. €69,000 per inhabitant (in the study 22 area) in 2010 or €135 million/km of coastline. Our results highlight the importance of (i) raising awareness to 23 ensure that public services and coastal managers can anticipate the consequences of SLR and (ii) incorporating 24 coastal ecosystems into the assessment of the adaptation options. Our findings could provide a basis for 25 participatory foresight approaches to build coastline adaptation pathways. 26 27

Abstract

International audience; Recent dramatic events have allowed significant progress to be achieved in coastal flood modelling over recent years. Classical approaches generally estimate wave overtopping by means of empirical formulas or 1-D simulations , and the flood is simulated on a DTM (digital terrain model), using soil roughness to characterize land use. The limits of these methods are typically linked to the accuracy of overtopping estimation (spatial and temporal distribution) and to the reliability of the results in urban areas, which are places where the assets are the most crucial. This paper intends to propose and apply a methodology to simulate simultaneously wave overtopping and the resulting flood in an urban area at a very high resolution. This type of 2-D simulation presents the advantage of allowing both the chronology of the storm and the particular effect of urban areas on the flows to be integrated. This methodology is based on a downscaling approach, from regional to local scales, using hydrodynamic simulations to characterize the sea level and the wave spectra. A time series is then generated including the evolutions of these two parameters, and imposed upon a time-dependent phase-resolving model to simulate the overtopping over the dike. The flood is dynamically simulated directly by this model: if the model uses adapted schemes (well balanced, shock capturing), the calculation can be led on a DEM (digital elevation model) that includes buildings and walls, thereby achieving a realistic representation of the urban areas. This methodology has been applied to an actual event, the Johanna storm (10 March 2008) in Gâvres (South Brittany, in western France). The use of the SURF-WB model, a very stable time-dependent phase-resolving model using non-linear shallow water equations and well-balanced shock-capturing schemes, allowed simulating both the dynamics of the over-topping and the flooding in the urban area, taking into account buildings and streets thanks to a very high resolution (1 m). The results obtained proved to be very coherent with the available reports in terms of overtopping sectors, flooded area, water depths and chronology. This method makes it possible to estimate very precisely not only the overtopping flows, but also the main characteristics of flooding in a complex topography like an urban area, and indeed the hazard at a very high resolution (water depths and vertically integrated current speeds). The comparison with a similar flooding simulation using a more classical approach (a digital terrain model with no buildings, and a representation of the urban area by an increased soil roughness) has allowed the advantages of an explicit representation of the buildings and the streets to be identified: if, in the studied case, the impact of the urbanization representation on water levels does indeed remain negligible, the flood dynamics and the current speeds can be considerably underestimated when no explicit representation of the buildings is provided, especially along the main streets. Moreover, on the seaside, recourse to a time-dependent phase-resolving model using non-stationary conditions allows a better representation of the flows caused by overtopping. Finally, this type of simulation is shown to be of value for hazard studies, thanks to the high level of accuracy of the results in urban areas where assets are concentrated.

Abstract

Technical and institutional capacities are strongly related and must be jointly developed to guarantee effective natural risk governance. Indeed, the available technical solutions and decision support tools influence the development of institutional frameworks and disaster policies. This paper analyses technical and institutional capacities, by providing a comparative evaluation of governance systems in Italy and France. The focus is on two case studies: Naples and Guadeloupe. Both areas are exposed to multiple hazards, including earthquakes, volcanic eruptions, landslides, floods, tsunamis, fires, cyclones, and marine inundations Cascade and conjoint effects such as seismic swarms triggered by volcanic activity have also been taken into account. The research design is based on a documentary analysis of laws and policy documents informed by semi-structured interviews and focus groups with stakeholders at the local level. This leads to the identification of three sets of governance characteristics that cover the key issues of: (1) stakeholders and governance level; (2) decision support tools and mitigation measures; and (3) stakeholder cooperation and communication. The results provide an overview of the similarities and differences as well as the strengths and weaknesses of the governance systems across risks. Both case studies have developed adequate decision support tools for most of the hazards of concern. Warning systems, and the assessment of hazards and exposure are the main strengths. While technical/scientific capacities are very well developed, the main weaknesses involve the interagency communication and cooperation, and the use and dissemination of scientific knowledge when developing policies and practices. The consequences for multi-risk governance are outlined in the discussion. ISSN:0921-030X ISSN:1573-0840

Abstract

National audience; La méthodologie présentée dans le présent article vise à simuler de manière la plus réaliste possible les franchissements par paquets de mer et la submersion qui en résulte en milieu urbain. Elle s'appuie sur des simulations régionales à locales de niveaux d'eau et de vagues pour établir des conditions de forçage pour un modèle à résolution de phase ("vague-à-vague") utilisant des schémas numériques adaptés. Ce modèle est alors utilisé sur un Modèle Numérique d'Elévation (MNE), intégrant les bâtiments, de manière à simuler simultanément le franchissement et la propagation de l'inondation. Cette méthodologie a été appliquée avec le modèle SURF-WB à la submersion survenue à Gâvres (Morbihan) lors de la tempête Johanna (10 mars 2008). Les résultats obtenus s'avèrent tout à fait cohérents avec les observations disponibles (zones de franchissement, étendue de l'inondation, hauteurs d'eau et chronologie). Cette méthode permet d'améliorer la qualité des résultats en milieu urbain par rapport aux approches plus classiques, notamment vis-à-vis de la vitesse des courants à terre. Le développement rapide et récent de ce type de modèle devrait permettre la généralisation de ce type d'approche dans les années à venir. Ce travail a été réalisé dans le cadre du projet JOHANNA (partenariat BRGM-UBO, cofinancé par la Fondation MAIF).

Abstract

In Portuguese case study, were considered two hazards with very different characteristics. Coastal erosion is mainly triggered by storms events. Coastal erosion is influenced by the regional context and the sedimentary budget in the coast (partially influenced by human action). For the same hydrodynamic conditions the coastal erosion can be reversible if sedimentary budget is positive or equilibrated, on the contrary, it is irreversible if the sedimentary budget is negative. Contrarily, most forest fires have an anthropogenic origin being one of the most predictable hazards. In the validation of the Move framework for these two hazards different methodologies were proposed. An Index of Coastal Erosion Exposure and Fragility, applied to three scenarios of erosion of land in the next 30 years (Very likely, Likely, Possible) was elaborated. It was also proposed Indicators of Coastal Erosion Resilience which were decomposed into capacity to anticipate, to cope, and to recover and cover five main types of resilience (i.e., physical, environmental, economic, social, and institutional). For forest fires were defined indicators for the three components and dimensions considered by the MOVE’s framework. Each one of these indicators has meaning in itself and can be used to promote vulnerability reduction, even though all indicators can be aggregated by dimension and component until obtain a single value to express the overall vulnerability. The main challenge was deciding on the weight of each indicator mainly of the social ones, of each dimension, and each component. Some of the indicators selected for coastal erosion and forest fire vulnerability assessment are hazard independent and can be shared by several hazards. The indicators lists presented for both test cases try to cover all the vulnerability roots, however some variables can be measured using another indicators according to the scale of analysis, data availability, and environment and social characteristics of the area. This reflects some flexibility on the framework operationalization without negative impacts in vulnerability assessment. The implementation of MOVE’s framework is important to enhance coastal erosion and forest fire risk management. If the factors that influence vulnerability are understood, state agencies will be in a better position to make informed choices regarding risk reduction and how the communities can be mobilized to collaborate on it.

Abstract

International audience; The main objective of the VULSACO (VULnerability of SAndy COasts to climate change and anthropic pressure) project was to investigate present day and potential future vulnerability of sandy coasts at the 2030 horizon, i.e. on a time scale related to climate variability. The method, based on a multidisciplinary approach bringing together geologists, geographers, physicists , social psychologists, engineers and stakeholders, was structured around 4 axes: field data analysis; numerical modelling; analysis of governance and stakeholder perceptions; and development of vulnerability indexes. This approach was designed to investigate vulnerability at a local scale and was applied to 4 contrasting beaches located in France: Sète Lido (Mediterranean Sea), Truc Vert and La Tresson beaches (Atlantic Ocean), and Dewulf (English Channel). The results focus on decadal and multi-annual beach trends at the Truc Vert beach site. There is almost no trend in beach volume at Truc Vert beach, although there is a variation in this parameter on a cycle of 2 to 3 yr, with variations related to wave energy and probably to indexes of climate variability. Numerical modelling identified the sensitivity of beach responses to changes in wave height and direction, especially in terms of subtidal morphology and the potential development of shoreline instability. Together with the observed offshore wave angle at the Biscay Buoy, these model results suggest that a potential change in wave angle due to climate variability could significantly modify the bars' morphology. The combination of data analysis and numerical modelling contributed to the development of vulnerability indexes designed for sandy coasts, which take into account climate-dependant variables such as waves. This allowed the differentiation of the sites in terms of vulnerability to erosion: Sète Lido and Truc Vert beach were the most and least vulnerable sites, respectively. These indexes help in identifying the dominant components of beach vulnerability, and provide potential for the study of how anthropogenic factors affect vulnerability. The study of stakeholder perceptions and decision-making with regard to climate-related risk also highlighted potential anthropogenic effects on beach vulnerability, and identified possible site-specific outcomes.

Abstract

Diagenetic mineral sequences in Triassic and Lower Lias sedimentary successions studied in the Balazuc borehole are seen to have modified the initial reservoir qualities of the formations. The upper part of the Triassic Lower Sandstone unit and the Hettangian Lower and Upper Calcarenite units were initially good quality reservoirs, whereas the Triassic Upper Sandstone unit and the Rhaetian Sandstone unit were initially average quality reservoirs, temporarily improved by pedogenesis. Early burial induced partial plugging of the initially porous bodies as a result of fluid exudation from proximal sediment bodies; the circulation of these fluids brought about alteration, dissolution and mineral deposition. Tectonic events associated with the formation of the Southeast Basin palaeomargin caused movement along the Uzer Fault and imparted a fracture porosity to the buried sedimentary formations. However, increasing subsidence and burial reactivated fluid circulation, dissolution and mineralization with further plugging of pore spaces. Present reservoir quality, as assessed from measured water porosity and neutron density well logs shows a changed reservoir distribution. Apart from the main Uzer Fault and one secondary fault (1644–1647 m) that today form drainage channels, the Triassic Lower Sandstone unit and its topmost breccia are now non-reservoirs, the Triassic Upper Sandstone, Rhaetian Sandstone and Hettangian Calcarenite units form a succession of residual-matrix-porosity reservoirs isolated by non-porous units.

Abstract

The Ardeche project of the Geologie Profonde de la France (GPF, or Deep Geology of France) programme aims at quantifying mass transfer along the margin of the Southeastern Basin of France, using drilling data. A very comprehensive geologic study has been made of the cores from the Balazuc well, including lithology, sedimentology, mineralogy and petrography. This enabled the determination of several lithologic units and of the evolution of their depositional environment. Petrographic study showed that the diagenetic evolution can be divided into four phases, from syn-sedimentary diagenesis to a late faulting-related phase. In order to provide a framework for these observations at the scale of the units, a geochemical investigation was carried out as well. It consisted of the unusual procedure of total rock analyses on core slabs up to 60 cm long, each sample representing a rocktype. In this paper we compare the geologic results with the chemical logs that were obtained from these analyses. The lithology and mineralogy of the formations give a specific chemical signature. The evolution with depth of the major elements defines trends that can be correlated with first- and second-order major and minor stratigraphic cycles, indicating that the base-level evolution has been recorded by these logs through detrital control. Using minor elements (Fe, Mn, Sr and Ba), the evolution with depth of several specific mineralogical phases indicates that the depositional environment and tectonic control of the sedimentation remained guides for the chemical composition of diagenetic deposits. Comparison with petrographic results shows that diagenesis occurred extremely rapidly, leading to a complete decrease in permeability of the series. The results show that this type of geochemistry can be a powerful tool to complete geologic observations.

Abstract

The coastal system is likely to suffer increasing costal risk in a global change context. Its management implies to consider those risks in a holistic approach of the different vulnerability components of the coastal zone, by improving knowledge of hazard and exposure as well as analyzing and quantifying present day and future territory vulnerability. The ANR/VMC2007/MISEEVA project (2008-2011) has applied this approach on Languedoc Roussillon region in France. MISEEVA approach relies on several scenarios for 2030 and 2100, in terms of meteorology (driver of coastal hazard), sea level rise, and also considering further trends in demography and economy, and possible adaption strategies Hazard has been modeled (SWAN, MARS and SURFWB), on the base of the presentday situation, sea level rise hypotheses, and existing or modeled data, of extreme meteorological driving f. It allowed to assess the possible surges ranges and map coastal zone exposure to: - a permanent inundation (considering sea level rise in 2030 and 2100, - a recurrent inundation (considering sea level rise and extreme tidal range) - an exceptional inundation (adding extreme storm surge to sea level rise and tidal range). In 2030, exposure will be comparable to present day exposure. In 2100, extreme condition will affect a larger zone. Present days social and economic components of the coastal zone have been analyzed in terms of vulnerability and potential damaging. Adaptation capacity was approached by public inquiries and interviews of stakeholders and policy makers, based on existing planning documents The knowledge of the present day system is then compared to the possible management strategies that could be chosen in the future, so to imagine what would be the evolution of vulnerability to marine inundation, in regards to these possible strategies.

Abstract

MISEEVA (2008-2011) aims to assess coastal zone vulnerability to marine inundation by integrating the physical and socio-economical aspects at different temporal (2010, 2030 and 2100) and spatial (local to regional) scales. The Languedoc Roussillon (France) region was chosen as a pilot site, focusing on local sites from Villeneuve-les-Maguelone to Carnon, in Herault. It required the development of a transdisciplinary methodology to enable transfers of knowledge and promote interdisciplinary iteration of methods throughout the project. In 2030, sea level rise (SLR) should not exceed 0.07m (IPCC, 2007). For 2100, SLR of 0.35m (A2 SRES scenario, GIECC 2007) and 1m (Rahmstorf, 2007, Grinsted et al, 2009), are both considered. As negligible changes in storminess are expected (IPCC, 2007, Deque, 2007), historical storms are therefore used as references to simulate exceptional inundations, in 2010, 2030 and 2100. Regional and local propagation of wind-generated waves and surges (wave set-up and atmospheric surge) are calculated using a chain of models and semi-empirical formulas. Then, maps of permanent, recurrent and exceptional inundations (due to SLR, tidal level, and surges) in 2010, 2030, and 2100 are drawn. Socio-economy in 2030 is believed to follow the present day trend in Languedoc-Roussillon (demographic growth, urbanisation and tourist development). Socio-economic evolution in 2100 is quite unforeseeable: scenarios for 2100 are being built based on contrasted potential adaptation strategy scenarios Designing a typology and valuation of present day assets help to value potential damages processes due to marine inundation on the coastal system at 2010, 2030 and 2100. Perception and response capacity knowledge to marine inundation risk is gained through residents, users and stakeholder surveys at the local site.Mixing physical and socio-economical approaches to evaluate the exposure of a territory to a hazard allows progression towards a systemic definition of vulnerability. Projection in the future points out the need to consider adaptation capacity as a main parameter of vulnerability evolution.

Abstract

International audience; LIFE Environment/RESPONSE project (2003–2006) aimed to evaluate and map, at regional scale, the impact of climate change on coastal risks (erosion and marine flooding), by anticipating the response to regional climatic change scenarios of coastal systems. These are described by their geomorphology, coastal processes, known hazardous events and existing defences. Application on Aquitaine and Languedoc Roussillon regions (France) assesses the likely increase of the coastal risks. In both regions, the weight of geomorphology and settlement development is underlined. The results point out the need for better knowledge on physical resilience capacity of the coast, assets values and vulnerability, and the urge of an integrated management approach of coastal risk, at least at the scale of sedimentary cell.
