河水位连续变化条件下潜水回水范围计算
Calculation of backwater range of phreatic water under conditions of continuous changes of river level
摘要
Abstract
A model was build for the calculation of the phreatic backwater range of the Kuihe River under the conditions of continuous changes of the river level. The model was solved by the second linearization method of the Boussinessq equation and the range was reasonably forecasted. The calculation results show that the backwater range of the phreatic water of the Kuihe River was about 65 meters. Groundwater within this range must be affected by water pollution over a long period. The backwater range was mainly affected by the permeability coefficient and specific yield. According to sensitivity analysis of the two factors, the permeability coefficient had a decisive influence while the specific yield had a limited influence on the backwater range.关键词
