【摘要】 在对城市排水系统产汇流特性分析的基础上,采用水文学与水力学相结合途径,建立了城市地面积水数学模型。模型能够可靠地模拟暴雨造成的城市地面积水的量级、面积、深度和历时,并借助GIS的功能动态地演示地面积水的涨消过程,为制定城市防汛减灾对策和措施提供水情及涝情信息。更多还原

【Abstract】 Based on analysing runoff yield and flow concentration characteristics in urban drainage systems, a mathematical model for storm water logging simulation is established by using the hydrologic and hydraulic methods The model can be used to simulate quantity, depth, cover area and lasting time of storm water logging during a storm event, and demonstrate dynamically the logging processes incorporated with GIS, providing necessary information for decision of flood prevention and disaster reduction更多还原
