Nevertheless, in western （north and central） part of France, the active tectonics related to the south Armorican and the Bay of Biscay context results sometimes in shallow earthquakes with magnitude above five （e.g., the Oleron seismic crisis, magnitude （local） = 5.2, 1972）. The Charente region is featured by semi-diurnal tides that reach about six meters in height during the high tide period. Inlets are the main features of the Atlantic margin geomorphology nearby the Charente. Minor tsunamis have been observed and reported in the past. Here, we present a tsunami modelling computed with the TELEMAC package that solves the non linear shallow water equations. This work helps to identify the role of the inlets that characterize the Charente＇s geomorphology on water wave＇s propagation. A tidal model is considered while the tsunami simulation is performed.
