A Study of Applicability of ERA5 dataset for Nearshore Wave Simulation

The purpose of this study is to investigate the applicability of ERA5 reanalysis data to force nearshore wave model(SWAN) in Korea. A nearshore wave model was set up to simulate wave transformations in December 2016, in Ilsan beach located in Ilsan-dong, Ulsan Metropolitan City. The numerical results by ERA5 inputs were compared with the results by ERA-Interim inputs. The ERA5-based simulation results show better agreement with field observations than the ERA-Interim ones do. In addition, the wave model results have been improved by applying whitecapping empirical formulas of Rogers et al.(2012) among physical parameters.
