Initial Concept of Stormwater and Flood Management in Beijing City

The acceleration of urbanization progress brings some water problems such as flood water,water scarcity,water pollution and so on.The rainwater harvesting measures in buildings and residential areas have better effect on control and utilization of design storm.But it is difficult to deal with larger storm especially over-design storm.Therefore,it is necessary that an integral stormwater and flood management in the whole city should be established based on the prediction,monitoring and simulation of rainfall runoff,stormwater drainage network and flood river to solve this problem.Based on the current condition of Beijing City,the initial concept of stormwater and flood management and some key problems needing further study are put forward with a view to promote the implementation of Beijing City stormwater and flood management and the construction of livable city.
