| Abstract: | Trihalomethane formation potential (THMFP) is an indicator of the cont ent of trihalomethane precursors in environmental media. The THMFP in soil cont r ibutes a large part to the pollution of water body in the form of non-point sour ce pollution due to surface runoff. A non-point source THMFP model is proposed to simulate the runoff of THMFP load under various rainfall and soil conditions. The model consists of two parts. One is the rainfall-runoff sub-model based on the modified Horton model in which the initial water content of soil is taken i nto account. The other part is the pollutant output model that employs the method of accumulative coefficient determined from field data. The model is verified with field survey data and the results are discussed. |
