Évolution du rivage et des petits-fonds du littoral du Nord de la France depuis le 19ème siècle

La façade nord des Hauts-de-France correspond à une frange côtière de 60 km orientée OSO-ENE ouverte sur la mer du Nord. De nombreux bancs sableux sont présents le long de ce littoral où ils forment des corps sédimentaires massifs parallèles à obliques au trait de côte, localisés sur l’avant-côte jusqu’à plusieurs dizaines de mètres de profondeur. Des levés bathymétriques ont été exécutés depuis les années 1830 dans cette région. Les résultats de ces levés hydrographiques sont conservés au format papier dans les archives du Shom.

Relative Contribution of Wave Setup to the Storm Surge: Observations and Modeling Based Analysis in Open and Protected Environments (Truc Vert beach and Tubuai island)

Recent events like the Xynthia (2010, France) storm illustrate the potentially devastating effect that storm surges can have on the coasts. Nearshore storm surges at the result mainly from two processes: atmospheric surges and wave setup. This paper investigate the relative wave setup contribution in the storm surge signal for energetic events and focusing on two cases: an open beach (Truc Vert beach, France) and a high island protected by a reef lagoon (Tubuai, French Polynesia).

Assessment of Flooding Hazards at An Engineered Beach during Extreme Events: Biarritz, SW France

This study focuses on flooding hazards along the Grande Plage of Biarritz. This pocket engineered beach, located in the south west of France, was highly battered by a series of storms during the winter 2013–2014 and experienced great damages to buildings and infrastructures. The vulnerability of this type of beaches to storm impact is assessed using the XBeach surf beat model. For validation purpose, a dedicated spectral wave model is also used on the coastal area to force XBeach at 15 m depth.

Casting light on forcing and breaching scenarios that lead to marine inundation: Combining numerical simulations with a random-forest classification approach

Identifying the offshore forcing and breaching conditions that lead to marine inundation is of high importance for risk management. This task cannot be conducted by using a numerical hydrodynamic model due to its high computation time cost (of several minutes or even hours). In the present study, we show how the random forest (RF) classification technique can approximate the numerical model to explore these critical conditions. We focus on the Bouchôleurs site, which is located on the French Atlantic coast and exposed to overflow processes.

Scalable Interactive Platform for Geographic Evaluation of Sea-Level Rise Impact Combining High-Performance Computing and WebGIS Client

As the climate is changing, more applied information on resulting impacts are required to inform adaptation planning . Over the last decade, the amount of information relevant to climate change impact assessment has grown drastically. This can particularly be illustrated in coastal areas, threatened by sea-level rise due to climate change, where a key recent development has been the delivery of precise and accurate topography obtained by Light Detection and Ranging (Li-DAR) at regional and national scales, i.e., respectively, large and small scales.

Investigating the effects of sea-level rise on morphodynamics in the western Giens tombolo, France

Rising sea level along with the occurrence of greater and more frequent storms would cause not only coastal flooding, but also beach erosion and shoreline retreat problems. The Almanarre beach along the western Giens tombolo is socio-economically and heavily vulnerable to accelerated sea level rise due to its high touristic value and low-lying topography. Therefore, it is necessary to quantify the impacts of sea level rise (SLR) on the morphodynamics in this area, e.g. to evaluate the relationship between the beach erosion and SLR.

Managed realignment to mitigate storm-induced flooding: A case study in La Faute-sur-mer, France

Storm-induced coastal flooding is among the most destructive natural disasters while climate change together with increased populations along the coast will enhance the associated risk. This study presents the comparison of conventional coastal defense schemes against managed realignment schemes in La Faute-sur-Mer, a small village located in the central part of the Bay of Biscay that was severely impacted during Xynthia in 2010.

Azimuth selection for sea level measurements using geodetic GPS receivers

Based on analysis of Global Positioning System (GPS) multipath signals recorded by a geodetic GPS receiver, GPS Reflectometry (GPS-R) has demonstrated unique advantages in relation to sea level monitoring. Founded on multipath reflectometry theory, sea level changes can be measured by GPS-R through spectral analysis of recorded signal-to-noise ratio data. However, prior to estimating multipath parameters, it is necessary to define azimuth and elevation angle mask to ensure the reflecting zones are on water.

Tidal downscaling from the open ocean to the coast: a new approach applied to the Bay of Biscay

Downscaling physical processes from a large scale to a regional scale 3D model is a recurrent issue in coastal processes studies. The choice of boundary conditions will often greatly influence the solution within the 3D circulation model. In some regions, tides play a key role in coastal dynamics and must be accurately represented. The Bay of Biscay is one of these regions, with highly energetic tides influencing coastal circulation and river plume dynamics.
