| Abstract: | Based the characteristics of smooth terrain,backwater effect of river water level and summer rainfall concentration in the northern plain cities,The key elements in design of municipal rainwater pipe network,such as collecting time,catchment area,runoff coefficient,rainfall recurrence interval,flooding velocity,rainwater inlets and so on are analyzed.The selection methods for the optimal values are put forward to achieve the goal of optimal design. |
