Numerical simulation of tidal bore in Hangzhou Gulf and Qiantangjiang

In this paper, a new numerical model, based on a set of non-linear shallow water equations is developed for the simulation of the formation and evolut ion of tidal bore in the Hangzhou Gulf and Qiantangjiang river of China. Th e numerical method and boundary conditions are described in detail. The met hod is validated against analytical solutions and experimental data. Simula tion of the actual tidal bore in Hangzhou Gulf and its propagation in the Q iantangjiang river are performed. Numerical results show that this proposed method is effective for the prediction of tidal bore and current flow at t he entrance of Qiantangjiang river. Copyright (C) 2001 John Wiley & Sons, L td.
