| The floodwave analysis for unsteady supercritical flow is performed. The numerical model. based on dynamic wave equation is presented by introducing the general Preissmann scheme and fore-sweep algorithm.The model is applied to Buffalo-Creek floods for proving its validity, and the simulation results have good agreements with those computed by DAMBRK and the observed data. It is also applied to Hyogi dam-break. The outflow hydrograph is derived based on the observed data and the analysis for the floodwave propagation is investigated. |
