a b s t r a c tThe main characteristics of wave energy potential over Eastern Mediterranean Levantine Basin, an area of increased interest for energy resources exploration/exploitation, is presented in this work. In particular, an integrated hindcasting platform consisting of state-of-the-art wind-wave numerical models at a very high resolution mode is utilized to produce a 10-year database for the wave energy potential in the Levantine Basin and the environmental parameters that affect it. The numerical results are analyzed by means of a variety of statistical measures focusing, apart from the conventional statistical information, on the potential impact of extreme values and the probability distribution functions that optimally describe the spatial and temporal distribution of the wave power potential over the Eastern Mediterranean sea area. The regions with increased values of wave energy potential are mainly the western and southern coastlines of Cyprus island, the sea area of Lebanon and Israel, as well as the coastline of Egypt especially around Alexandria. Over these areas, relatively low but also stable, and hence exploitable, wave energy potential is revealed. However, non-trivial impact of infrequent values is also recorded.

“…This wave data set was obtained with the WAM model and forced by the wind output of the regional atmospheric model REMO, which in turn was forced by the global re-analysis data of NCEP. The HIPOCAS database has been extensively validated for wind, wave and sea-level parameters (Musić and Nicković 2008;Sotillo et al 2005). This simulation, like most, has some limitations in terms of properly reproducing certain storm events but it generally reproduces mean values quite well (Ratsimandresy et al 2008).…”

The effects of climate change are currently a red-hot issue in the scientific community. However, little attention has been paid to the effects of climate change on the wave climate and, in particular, on wave directionality. In this study, we developed a methodology of trend analysis and extrapolation of mean wave climate. We used the parameters of a typical wave rose: frequencies of wave height intervals and directional sectors. The trend over time was estimated by means of linear regression analysis after applying a transformation according to the nature of the (compositional) data. Then, the wave climate was extrapolated up to 2050 assuming the same previously estimated trend and part of the uncertainty was assessed with the bootstrapping technique. Additionally, to get an idea of the magnitude of the consequences of the identified trends, we carried out an impact assessment, in terms of coastal morphodynamics and harbour operability, comparing the present situation with the extrapolation. To assess the impact on coastal morphodynamics, we compared the gradients of long-shore sediment transport to evaluate possible changes in beach retreat/accretion tendency, and to assess harbour operability, we studied the possible impact on harbour agitation in three port case studies. This study was carried out on the Catalan coast (NW Mediterranean Sea) and was based on 40 nodes of 44 years of wave hindcast data. The main impacts on the wave climate were found to be a reduction in the waves coming from the north and northeast and an increase in events coming from the south. This apparently significant change in directionality could result in changes in the prevailing dynamic pattern along more than 70 % of the Catalan coast (e.g. some apparently stable beaches could become erosive) although these results have associated a large uncertainty and are not statistically significant. On the other hand, harbour agitation is expected to increase Climatic Change (2012) 115:667-691 DOI 10.1007 M. Casas-Prat (*) : J. P.

“…present back to 1948. NRA1 data have been analyzed and used to perform hindcasts in various studies through physically-based models (Sterl et al, 1998;Swail and Cox, 2000;Cox and Swail, 2001;Cieślikiewicz and Paplińska-Swerpel, 2008;Musić and Nicković, 2008;Pilar et al, 2008;Ratsimandresy et al, 2008;Rusu et al, 2008). Nonetheless, use of numerical models may be limited by their complexity, high computational requirements and the need of accurate bathymetric data (Browne et al, 2007).…”
