“…Moreover, they are subject to sea surges during storms due to their low elevations. In order to better understand the effectiveness of Morphodynamics of beach/dune systems: examples from the coast of France dunes against storm surges (Sabatier, 2008), it is important to investigate the dune/beach system and its imbrications with the shoreface. The Camargue coastline presently undergoing significant erosion does not present any continuous natural dune formations (Augustinus et al, 1990;Suanez, 1997).…”

“…The episodic retreat of the shoreline (∆r ST ) is calculated using the numerical model Sbeach (Storm-induced BEAch CHange) (Larson and Krauss 1989) which reproduces the erosion and the retreat of the beach face and the dune during storms (Sabatier et al 2002, Sabatier 2008. SBEACH is a two dimensional model which uses the wave height, wave period and water level time series and the morphology (profile) as main inputs.…”

Determination of set-back lines on eroding coasts. Example of the beaches of the Gulf of Lions (French Mediterranean Coast)

The study presented here describes a method for defining set-back lines along eroding coasts. The method (a mathematical model) combines the long-term shoreline retreat trend with short-term shoreline erosion (during storms). Simulations are carried out for 2030 and compared with the beach width to determine whether the shoreline is likely to shift onshore. The mathematical model is applied to the Frontignan and Carnon beaches (south of France). Both sites possess hard engineering coastal structures and downdrift erosion on the natural beaches. The set-back lines indicate that beaches with groynes are generally wide enough to resist shoreline retreat, while the downdrift "natural" beaches are not. We discuss the possible utilisation of set-back line estimations.

This work aims to better understand the physical processes governing the wave propagation in a vertically sheared current and the resulting nearshore circulation patterns. It is based on a high resolution hydro-morphodynamic field campaign, ROUSTY2014, collecting a comprehensive hydro-morphodynamical dataset during a full winter season. The overall analysis highlights three main circulation patterns, largely controled by the bathymetric features and by co-working or competing wind and waves forcings. Regarding the vertical structuration of the circulation, most of field observations shown seaward directed circulation with onshore component close to the air/sea surface whose intensity varies according to incoming wave conditions. Forth, vertical shear increase when breaking happen close to sensor location and orientation of mean circulation depend on wind direction.
