Abstract
Storm events lead to sudden and drastic impacts on coastal areas, causing serious damages, flooding and severe coastal erosion. These extreme weather conditions seriously affect the nearshore system by reshaping the shoreline and moving large amounts of sand cross-shore. For the assessment of the consequences of such extreme storm events, an interdisciplinary approach simulating atmospheric, wave, hydraulic and geological processes is required, necessitating the use of sophisticated numerical models. Within this study, MIKE 21 and XBeach numerical models are employed for the estimation of the prevailing wave, hydrodynamic and morphodynamic characteristics in a coastal area. The results of the two models are utilized in a comparative approach to assess coastal processes. Furthermore, an alternative solution is also proposed for effective protection of a nearshore area. The approach is demonstrated in the coastal zone of the city of Rethymno in Greece, an area significantly affected by extreme storm events in the recent past, and results are presented and discussed.
