heal.abstract	The coastal regions are often highly urbanized with a large proportion of human dwellings and activities and they appear great natural wealth with important ecosystems. Nevertheless, these environments are vulnerable because of natural risks (e.g. erosion), and due to land use change (overexploitation of natural resources, pollution, etc.), the intense residential pressures, and mass tourism. While coastal erosion, severe floods, inundation of coastal low slope areas, wetlands destruction and salinization of the lagoons and coastal lakes keep striking the coastal areas, the prediction of long-term climate changes constitutes a crucial step. In order to achieve that, one should take into consideration a number of factors that makes the problem complex. Among others the following factors are included: bathymetry of sea bottom, existing port and coastal works, erosion, sea level rise, geometry of the urban environments (e.g. roads, buildings, drainage systems). Hence, numerous researchers have contributed to the development of useful tools to predict and calculate the causes of a coastal flooding event arising from i.e. storms and storm surges, sea level rise and tsunami. These phenomena result in wave overtopping and wave run-up on shore. The present research has been accomplished in the framework of European Union Seventh Framework Programme (FP7/2007-2013) for the research project PEARL (Preparing for Extreme And Rare events in coastaL regions). The PEARL project seeks to fill in the lack of interaction between social aspects and technical measures – appearing to be a major hindrance for solving some of the greatest problems associated with floods and flood-related disasters. The main goal of PEARL is to develop adaptive, sociotechnical risk management measures and strategies for coastal communities against extreme hydro-meteorological events minimising social, economic and environmental impacts and increasing the resilience of Coastal Regions in Europe. The present work is based on the study of Tsoukala et al. (2015), which is an integrated methodology for long-term prediction of climate changes and their respective impacts on coastal zones. Starting from the wind climate change and reaching the calculations of wave overtopping and run-up. This is achieved by the combination and cooperation of various numerical models for predicting and simulating the natural phenomena. Finally, the proposed methodology is applied to the coastal region of Rethymno in Crete Island of Greece, resulting in the production and construction of useful data bases and information for potential upcoming storms and their respective impacts. According to the above study, the offshore wave data used for hindcasting and forecasting, obtained through SWAN model which is a third-generation wave model that computes random, short-crested, wind generated waves in open sea, coastal regions and inland waters. With offshore wave data available, a definition and categorization of the storm events is accomplished in order to distinguish the severity of each event. These valuable data of simulations are then used by the present work and fed, as boundary conditions, into a wave propagation model to simulate the wave characteristics and the hydrodynamic field nearshore (MIKE21 PMS, HD, (DHI, 2007)). Subsequently the characteristic wave height, as transformed through various physical processes (shoaling, refraction, breaking, etc), is used to simulate wave run-up with an improved Boussinesq-type model MIKE21BW, (DHI, 2007) and to estimate the wave overtopping (EurOtop, 2007) in selected sections along the coastal zone of Rethymno.	el
