The results from the investigation indicate that the model is accurate and reliable. The model is easily implemented on a microcomputer and thus avoids the extensive time and costs associated with modeling urban water quality on mainframe computers, using existing complex simulation models. The model can be used to generate pollutant emission frequency functions for small urban watersheds that possess a range of difference rainfall inputs and cultural factors. 收起
