Laboratory experiments on cross‐shore beach morphodynamics are presented. A lightweight sediment (density ρ s = 1.19 g cm −3 ) model is used in order to fulfill a Shields number and Rouse scaling. This choice aims at correctly reproducing bed load transport as well suspension dynamics. Terraces barred profiles obtained the also present close similarities with observed field. In question concept of equilibrium profile, wave forcings conforming JONSWAP spectrum were imposed over long periods...
Abstract The central part of the Gulf Lions shoreline is characterized by many coastal wetlands that resulted from interaction between a process regularization migrations littoral barriers and slow filling back-barrier areas riverine marine inputs. Analyses Late-Holocene deposits with very high-resolution multi-proxy study two sediment cores, allow us to reconstruct evolution this system. Two main Holocene units are identified overlying Pliocene carbonate continental formation. lower unit...

Most of the Mediterranean coastal porous aquifers are intensively exploited. Because climatic and anthropogenic effects, understanding physical geological controls on groundwater distribution flow dynamics in such is crucial. This study presents results a structural investigation system located along coastline Gulf Lions (NW Mediterranean). A key aspect this relies an onshore‐offshore integrated approach combining outcrops, seismic profiles, borehole data analysis. multidisciplinary provides...
Abstract The Maguelone shore extends along the northern coast of Gulf Lions margin, West Rhône delta and East some high gradient coastal streams that have been providing most clastic sediments to margin since early Miocene. This 10 km wide area comprises an onshore small watershed (15 long) in low-lying carbonate hills, kilometer marshes, sandy beach shoreface featuring local low sedimentation. Deposit architecture such a zone records dynamics incised valley fill under influence rivers...

Summary The topographical complexity of coral reefs is primary importance for a number hydrodynamical and ecological processes. present study based on series high‐resolution seabottom elevation measurements along the Maupiti Barrier Reef, French Polynesia. Several statistical metrics spectral analysis are used to characterize spatial evolution geometrical structure from reef crest backreef. A consistent fractal‐like power law exists in density bottom length scales between 0.1 7 m, while at...

Abstract The sandy littoral of Sète, with its barred shoreface, is one the three studied sites thematic action “Morphodynamics beaches” French Programme National d’Environnement Côtier (PNEC), selected because microtidal wave-dominated characteristics and long time series available data. During PNEC program, principal results obtained show that morphological evolution sedimentary bars can be synthesized according to two conceptual models, in reaction hydrodynamic variability.

Abstract A very high resolution seismic investigation has for the first time allowed imaging of sedimentary infill a Mediterranean lagoon. The Leucate lagoon is part system located along shore western Gulf Lions, from Rhone delta to Spanish border. These lagoons are separated and protected sea by sandy barriers, also called lidos, which result process regularization waves. data, obtained using boomer-Seistec, coupled with lithological radiocarbon data [Martin, 1978] previously collected...
