典型村落不同下垫面降雨径流污染物积累与冲刷规律
Accumulation and Wash-Off Characteristics of Pollutants from Rainfall Runoff on Different Type Underlying Surfaces for a Typical Rural Village
摘要
Abstract
Rainfall runoff data of three different rural underlying surfaces (the roof,courtyard and road) in Shatanggang Village,Zhoutie Town,Yixing City,was used for model fitting,and the models of the pollutants accumulation in runoff and rain scouring were created.The relationships between pollutants in runoff and rainfall intensity of different rural underlying surfaces of typical villages in Yixing were studied.The result shows that there were good linear relationship between runoff pollutant concentrations in [C(t)] and effective rainfall depth Hef.Model formula can be directly used to calculate the parameters of small and medium rainfall intensity (<0.1 mm/min).The model generally has a good precision,fits with the measured results,and can be used to analysis characteristics of pollutants accumulation in runoff and rain scouring of different rural underlaying surfaces in typical area of Taihu Lake Region.关键词
