ARTEMIS 3.0 : a finite element model for predicting wave agitation in coastal areas and harbours including dissipation D. Aelbrecht Laboratoire National d'Hydraulique, Electricite de France, E-mail: D-P.Aelbrecht@der.edfgdf.fr Abstract We present here recent developments concerning the integration of dissipation processes in ARTEMIS 3.0, a finite element model for wave propagation towards the shore and harbours agitation. The dissipation considered is linked to surf-breaking and bottom friction. The developments are validated against some reference test cases and applied to a real coastal geometry studied on a physical model. Comparison with experimental measurements shows that dissipation is required for the model to retrieve a reliable wave agitation level. 1. Introduction ARTEMIS 3.0 is a numerical model being developed at the Laboratoire National d'Hydraulique of Electricite de France within the TELEMAC structure. TELEMAC is an integrated system for hydroinformatic
