[A study on non-point source pollution models].

Abstract

With the effective control of industrial wastewater, pollution of non-point sources has become increasingly important in China. The understanding of non-point source pollution processes, mostly through mathematical models, is thus a prior knowledge to its effective control. A review is presented in this paper, regarding the development of non-point source pollution models. The conceptualization, structure and major processes of non-point source models are systematically summarized and several widely applied models are compared so as to assess its state of art. The future development trends of non-point source model are also discussed.
