Nonpoint pollution simulation models are parts of a category of "loading Models" which represent the inputs and movements of materials from the point of origin to watercourses. These models interface with water Quality models and usually provide input concentrations and flow rates. However, simulation for the process of nonpoint pollution generation in urban areas is quite difficult. in this paper, the author's work suggested a new procedure to calculate the output of nonpoint pollution in urban areas when surface...

Nonpoint pollution simulation models are parts of a category of "loading Models" which represent the inputs and movements of materials from the point of origin to watercourses. These models interface with water Quality models and usually provide input concentrations and flow rates. However, simulation for the process of nonpoint pollution generation in urban areas is quite difficult. in this paper, the author's work suggested a new procedure to calculate the output of nonpoint pollution in urban areas when surface runoff occurred. The basic computation of the procedure included the kinematic flow model, the pollution transportation equation, the washout of pollutants by surface runoff and the discharge ratio of nonpoint pollution, etc.

It was proved that the method was feasible in the south cities of China. This paper indicated that the loading by surface runoff of ordinary rainfall account for 87% of annual loading.The...

Using the STORM model which has been modified washoff of pollutants by surface runoff were estimated. The method which rainfall load was used to estimate annual pollution loadings of Chengdu was presented in this paper.It was similar to result which had been estimated by the method of unit area loads used by American scholars. It was proved that the method was feasible in the south cities of China. This paper indicated that the loading by surface runoff of ordinary rainfall account for 87% of annual loading.The runoff and washoff of ordinary rainfall must be considered in calculating pollution load for long period.

本文以成都市为例,使用修正的STORM模型计算一次标准降雨的径流污染负荷;使用“降雨负荷法”进行城市径流污染年负荷量的估算.文章指出年负荷中非标准降雨冲刷将起着主导作用,仅用标准降雨来估算一个城市的长期污染负荷是不可行的.
