Caractéristiques spatiales de la formation des surcotes marines dans le Golfe du Lion. Spatial charcateristics of sea-surges formation in the Gulf of Lions

This paper is based on the analysis of hourly tide measurements at four tide gauges stations around the Gulf of Lions: Marseille, Grau-de-la-Dent, Sète and Port-Vendres. For each tidal value, surge heights have been determined to keep only the atmospheric forcing on the level of the Sea. The aim is...

description	This paper is based on the analysis of hourly tide measurements at four tide gauges stations around the Gulf of Lions: Marseille, Grau-de-la-Dent, Sète and Port-Vendres.
