| Abstract: | According to topographic and geomorphologic characteristics of the cities in northern plain,the river water level,the rainfall centralization and the rainwater mouth on accepting water situation in summer,some key elements are analyzed in several municipal rainwater pipe network designs,such as inlet time,catchment area,runoff coefficient,recurrence interval,flood velocity of flow,and the rainwater accepting well.The methods of choosing the best fetching value are proposed in order to achieve the goal of optimizing design. |

| Keywords: | plain city rainwater system inlet time catchment area runoff coefficient |
