| Abstract: | Probability analysis method is put forword to estimate the long term operation efficiency of urban concave down greenbelt which stores and infiltrates rainfall runoff.Case study was also carried out for proper design of the concave down greenbelt based on the 20 year statistical data of the hourly rainfall characteristic parameters in Shanghai area.The results show that this method can ensure the safety of the engineering design of urban concave down greenbelt,and that the optimal practical concave depth was 80~160 mm,under which the storage infiltration efficiency could reach up to above 90%. |
