Coastal applications from nadir altimetry: example of the X-TRACK regional products
In the coastal ocean zones, satellite altimetry data processing and interpretation poses specific difficulties, due to the interaction of the radar signal with land topography, inaccuracies in…
Satellite radar altimetry water elevations performance over a 200 m river: Evaluation over the Garonne River
For at least 20 years, nadir altimetry satellite missions have been successfully used to first monitor the surface elevation of oceans and, shortly after, of large rivers and lakes. For the last 5…
Investigating the impacts of the regression of Posidonia oceanica on hydrodynamics and sediment transport in Giens Gulf
Posidonia oceanica plays a significant role in the stabilization and protection of the coast in Gulf of Giens. Unfortunately, its distribution has been declining remarkably due to both…
Nonlinear dynamics of the sea level time series in the eastern English Channel
Coastal flooding due to surge events represents natural hazards with huge potential consequences for coastal regions. Sea level time series display variations on a large range of timescales, with…
Short-term forecasting of saltwater occurrence at La Comté River (French Guiana) using a kernel-based support vector machine
Saltwater intrusion into rivers is a major concern for freshwater exploitation and management in French Guiana (South America). To detect and analyse saltwater occurrence, a permanent station was…
Temporal fluctuations in the trophic role of large benthic sulfur bacteria in mangrove sediment
Filamentous sulfur bacteria of the genus Beggiatoa form large mats covering the sediment in the shallow waters of a Guadeloupean mangrove (French West Indies). The abundance of these…
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…
Analyse des niveaux d'eau avec l'action des vagues au droit d'une plage de Méditerranée
La façade maritime méditerranéenne est bordée par plusieurs départements littoraux sur lesquels des enjeux de gestion du Domaine Public Maritime naturel (DPM) forts existent. La délimitation du…
Historical Sea Level in the South Pacific from Rescued Archives, Geodetic Measurements, and Satellite Altimetry
Automatic sea-level measurements in Nouméa, South Pacific, started in 1957 for the International Geophysical year. Data from this location exist in paper record for the 1957–1967 period, and in…
Homogenous regions based on extremogram for regional frequency analysis of extreme skew storm surges
To resist marine submersion, coastal protection must be designed by taking into account the most accurate estimate of the return levels of extreme events, such as storm surges. However, because of…
