This paper describes the MAREGOT (MAnagement des Risques de l'Erosion coti\ue8re et actions de GOuvernance Transfrontali\ue8re) approach to evaluate hydro-mophodinamic behaviuor using different methods on embayed beach in eastern Liguria (Mediterranean NW). Project aimed at the joint prevention and management of the risks arising from coastal erosion in the cooperation area; It is strategic project of 2014 - 2020 INTERREG V Italy - France (Maritime). The research was composed by field survey, coastal modelling and remote sensing; as a first step, investigation was conducted comparing two topo-batimetric surveys which were made six months apart. At same time coastal video monitoring, composed by two cameras, was used to evaluate principal surface currents and coastal model XBeach was computed to simulate hydrodynamic evolution. In all three applied methods, results came out cross-shore flow close to coastal structures, which could be used by local authorities to define coastal manager plan, evaluating risks related to seaward flows for bathers
