河流水质模拟计算中,综合衰减系数起着非常重要的作用。采用单一方法对综合衰减系数进行率定时,由于方法本身的局限性等因素,水质模拟效果较差。为提高模拟精度,联合运用最小二乘法与最速下降法率定综合衰减系数。以沙颍河阜阳闸至颍上闸段为背景,作了实例计算,取得了较好的效果。

Synthetic attenuation coefficient plays a very important role on simulating river water quality. Due to the limitations of a single method itself, water quality simulation effect is poorer. In order to improve simulation accuracy, this paper applies least -square method and the steepest descent method to rate at synthetic attenuation coefficient. The case study about the section of Shaying River from Fuyang to Yingshang shows good result.
