000004739 520__ $$2eng$$aA model is developed that can predict ßood wave propagation on city streets with enough resolution that individual buildings can be resolved in the computational grid. Storm sewers are incorporated as distributed point sinks. Basement ßooding is also included as local storage. Large objects are handled as prolate spheroids and are allowed to move and rotate according to the local ßow Þeld. The model is presented as a tool for urban design and emergency planning and can be potentially coupled with a weather forecasting system for real-time operation. The mathematical basis for the simulation is based on a computational scheme capable of handling wet and dry cells and arbitrary topography. Debris transport is accomplished by a Lagrangian technique and post-processing of the velocity and vorticity Þelds after each time step. The ßow equations are solved by a Þnite-volume scheme while the debris transport is carried out by solution of a large system of ordinary differential equations.
