Abstract

Some ideas for improving the accuracy of storm surge prediction models are discussed. A detailed coastal flooding model is applied to the flooding of Chittagong in the April 1991 disaster, but results are only illustrative due to the lack of good topography data. The influence of waves on wind stress forcing and bottom friction is discussed. Some recent results from a coastal observation tower taken during a typhoon show enhanced stress compared with values from empirical formulae in the literature. A new model for improving the representation of typhoon wind fields in areas surrounded by mountains is presented. Its applicability for storm surge computation is demonstrated using observations of a typhoon and surge in Osaka Bay.
