Quantifying uncertainties of sandy shoreline change projections as sea level rises
Sandy shorelines are constantly evolving, threatening frequently human assets such as buildings or transport infrastructure. In these environments, sea-level rise will exacerbate coastal erosion…
Identifying 2010 Xynthia Storm Signature in GNSS-R-Based Tide Records
In this study, three months of records (January–March 2010) that were acquired by a geodetic Global Navigation Satellite Systems (GNSS) station from the permanent network of RGP (Réseau GNSS…
Decadal-scale Dynamics and Morphological Evolution of Mangroves and Beaches in a Reef-lagoon Complex, Mayotte Island
Mayotte Island is characterized by a vast coral reef-lagoon complex comprising significant mangrove development and numerous pocket beaches nested between volcanic headlands. Since 2005, field…
Characterization of Sea-level Variations Along the Metropolitan Coasts of France: Waves, Tides, Storm Surges and Long-term Changes
With 5853 km of coastlines facing the North Sea, the English Channel, the Atlantic Ocean and the Mediterranean Sea, France displays littoral zones exposed to a wide spectrum of wave climates,…
2D and 3D modelling of offshore sandbank dynamics
The coastal zone is an important resource both socially and economically. Globally, coastal zones are under increasing threat from the effects of climate change, erosion and flooding.…
Earthquakes and extreme rainfall induce long term permeability enhancement of volcanic island hydrogeological systems
Earthquakes affect near-surface permeability, however temporal permeability evolution quantification is challenging due to the scarcity of observations data. Using thirteen years of groundwater…
Intertidal topography mapping using the waterline method from Sentinel-1 & -2 images: The examples of Arcachon and Veys Bays in France
Intertidal flats lying as a buffer zone between land and sea provide critical services including protection against storm surges and coastal flooding. These environments are characterized by a…
On the use of long term observation of water level and temperature along the shore for a better understanding of the dynamics: Example of Toulon area, France
A dense network of instruments has been deployed within harbors along the Mediterranean coast, in the Toulon Metropole area, between the Hyères islands and the Sanary Bay in the framework of the…
Climate-scale changes of the semidiurnal tide over the North Atlantic coasts from 1846 to 2018
We investigated the long-term changes of the principal tidal component M₂ over the North Atlantic coasts, from 1846 to 2018. We analysed 9 tide gauges with time series starting no later than 1920…
The Seasonal Cycle of Mean Sea Level in the North East Atlantic Ocean
The analysis of long-term tide gauge data collected in the Northeast Atlantic Ocean reveals that the seasonal cycle of mean sea level (hereafter MSL) exhibits amplitudes of up to 0.4 m. The…
