以奎河为例，构建河水位连续变化时潜水回水模型，使用Boussinessq方程的第二种线性化方法对模型进行求解，并对回水范围做出预测。结果表明，奎河两岸潜水的回水范围在65 m左右，该范围内的潜水势必长期受到河水污染的影响。回水范围计算的主要参数为渗透系数和给水度，通过二者对回水范围的敏感性分析可知，渗透系数对回水范围有决定性的影响，给水度对回水范围的影响有限。

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.
