The application of storm water management model in comprehensive planning of urban drainage and flood control

摘要

The drainage pipeline network model uses modern hydrology, hydraulics, mathematical modeling and computerized simulation to simulate the characteristics of urban drainage pipeline network system. Storm Water Management Model (SWMM for short) is the most widely used tool for modeling and analysis of drainage pipeline network model. It introduces SWMM modeling, simulation evaluation and analysis process, and carries out evaluation on drainage capacity of drainage pipeline network, and analysis on waterlogging causes and risks. The results show that, the SWMM has very good simulation results, it can provide a basis for scientific decision-making in urban drainage pipeline network planning.
