Abstract

A model of predicting coastal currents under non-stationary meteorological and wave conditions is eveloped. The current prediction model is composed of meteorological reanalysis data, a meso-scale weather prediction model and a coupling wave and surge model. The model is applied to the Joetsu Coast for predicting coastal currents and the predictions are compared with observations. The prediction model is also extended to statistically modeled time series of winds and waves. It has been found that coastal currents calculated by the prediction model depend strongly on ocean wind.
