摘要：Take a "rainwater management unit" of Huazhong University of Science and Technology (HUST) as the research object and use Storm Water Management Model software to preset different development strength indicator in the catchment area under the circumstances of design rainfall and actual rainfall (refer to rainstorm data on June 18, 2011); carry out hydrological simulation of total rainwater runoff, peak runoff value, flow velocity and duration of water retention and so on in such catchment area through simulation test on data of drainage pipe at end of the catchment area; summarize the hydrological law of urban catchment area under circumstance of different site development intensity through analyzing the simulation test and simulate the effect of rainwater runoff control by different low-impact development measures, thus demonstrating the coupling relationship between site development intensity and landscape hydrology
