| Abstract: | How to simulate the urban building group in a simple and accurate way is one of the major problems in the dam-break flood flow evolution calculation.The equivalent roughness simulation method and the relevant flume experiment based on the equivalent roughness value,which has been proved successful in a certain dam-break flood flow evolution study,is presented in this paper. |
