Applying POT methods to the Revised Joint Probability Method for determining extreme sea levels
Newly exposed concepts of POT declustering (Bernardara et al., 2014) within the GPD-Poisson model are applied to the joint probability of tide and surge for determining extreme sea levels, as a…
Contrasting records of sea-level change in the eastern and western North Atlantic during the last 300 years
We present a new 300-year sea-level reconstruction from a salt marsh on the Isle of Wight (central English Channel, UK) that we compare to other salt-marsh and long tide-gauge records to examine…
Sea level time series and ocean tide analysis from multipath signals at five GPS sites in different parts of the world
We present sea level observations derived from the analysis of signal-to-noise ratio (SNR) data recorded by five coastal GPS stations. These stations are located in different regions around the…
Coastal flooding of urban areas by overtopping: dynamic modelling application to the Johanna storm (2008) in Gâvres (France)
Recent dramatic events have allowed significant progress to be achieved in coastal flood modelling over recent years. Classical approaches generally estimate wave overtopping by means of empirical…
Modélisation des niveaux marins extrêmes associés à la circulation des cyclones Lenny (1999) et Omar (2008), commune de saint-pierre, littoral nord-ouest de la Martinique
Les submersions marines sont le plus souvent associées à des conditions météorologiques locales de tempête et aux phénomènes bien connus de surcote résultant du cumul de l’effet barométrique…
Improving the estimation of extreme sea levels by a characterization of the dependence of skew surges on high tidal levels
The knowledge of the statistical distribution of extreme sea levels at the coast is of utmost importance for the characterization of flood risks in coastal areas. In this study we consider that…
Ces tempêtes extrêmes que l'histoire ne nous a pas encore dévoilées
Les études d'aléa de submersion marine s'attachent à définir des valeurs extrêmes pour les niveaux marins et les houles et à combiner ces valeurs afin de produire un aléa de référence à la côte.…
Sea level surges of June 2011 in the NE Atlantic Ocean: observations and possible interpretation
We present a synthesis of tide gauge data recorded on June 26–28, 2011, along the NE Atlantic and the English Channel coastlines, which show a significant sea level disturbance observed from…
GPS observation of geophysical deformations induced by non tidal loading
The temporal and spatial redistribution of the environmental masses deform the surface of the Earth. These deformations are observable by space geodetic techniques such as GNSS. Since highly…
Effects of waves on coastal water dispersion in a small estuarine bay
A three-dimensional wave-current model is used to investigate wave-induced circulations in a small estuarine bay and its impact on freshwater exchanges with the inner shelf, related to stratified…
