The Arcachon tidal inlet (France) is a sandy place where tidal currents, swells and storms produce important sand movements. For example the emerged sand banks move several tens of meter a year. To study and understand these movements traditional methods are often inefficient. Remote sensing seems to be the best means to follow and quantify year after year sand movements. Two SPOT scenes have been processed to carry out bathymetric maps. From these maps we extrapolated both channels' and sand banks' movements and computed the sediment volumes between the water surface and a depth of 5 meters. Below this depth, the radiances keep a constant value whatever the depth change.
