Abstract
With the rapid development of urbanization, impervious areas spread quickly, which have greatly influenced regional hydrology and water resources. The water quality is getting worse and worse. The flood and drought disasters have aggravated. Human living environment has changed and consequently sustainable development of economy is restricted. The drainage pipe network plays a very important role in urban drainage and flood control. In the study, using of computer technology, the drainage capacity of study area in different design rainstorm return periods (P = 0.25, 0.5, 1, 2, 5, 10 a, respectively) is analyzed and simulated by Storm Water Management Model (SWMM). Part of the pipe network that are filled slowly and change great are found out fewer than 6 design rainstorms, which provide the basis for reconstruction of urban conduits. The simulation results can provide strong technical support for the city drainage system planning and management.
