摘要
WASP是美国国家环保署(EPA)推荐使用的水质模拟软件,本文利用Brandywine河实测结果,验证了WASP模型的水质模拟效果,模拟结果与实测符合较好,证实了WASP模型是一种有效、实用、可靠的水质模型。为了提高模拟效果,分析了模型主要参数的敏感度,发现水温对溶解氧影响最大、BOD衰减系数影响次之。灵敏度分析对模型参数选取和误差分析有指导意义。
WASP model is a water quality simulating software recommended by EPA. By comparing the results of WASP model with the field measured data of Brandywine River, the WASP model is testified to be an effective, pragmatic and reliable water quality model. The sensitive analysis of dissolve oxygen （DO） for the maior model parameters indicates that the water temperature is the highest sensitive parameter and the 20℃ BOD attenuation coefficient is the second. The result of sensitive analysis is favorable to choose suitable model parameters and analyze simulation errors in water quality simulation.
