Abstract
According to the progress of sewer system consolidation, the importance of the pollution in the public water bodies by the non-point pollutant load is increasing. The pollutant deposited on the surface of the catchment area and discharged during the storm event flow into the public water bodies. To preserve water quality in the public water bodies and to propose some effective strategies, it is necessary to clear the runoff characteristics of pollutant load associated with the catchment area characteristics. In this study, we compared the runoff characteristics of the pollutant load using series of observed data during storm event that were collected from storm sewer pipe over 7 cities for the 32 storm events. As a result of analysis, we quantified the contribution of land use, amount of rainfall and antecedent dry period. It is of great use for modeling the relationship between urban development and water quality conservation.
