Demonstration Research Of Flood Control And The Hydrogeological Distribution Of Beijing Urban Area

Building the demonstration of flood control site in Bali Zhuang area, based on the study of hydraulical conditions of Beijing urban area. The automatic monitering system was first time used in this Demonstration research and received a lot of monitering data. The experiments has started two years, according to the information of catchment water, disposal of water ,and water recharge , the roof water catchment & recharge system in south is better than that in north. Since the old style building has the trait of big density of construction & small part of road and green land area, the catchment efficiency of rain water is high, and also its control role for the rain water is in evidence.
