河流域含水层水力耦合模型

 

(1)    河水运动数学模型:

式中,为河流过水断面面积;为时间;为河流流量;为河流与含水层水量交换强度;为河水淹没宽度,为沿途汇入或引出流量;为河流长度坐标;为狄拉克单位脉冲函数。

(2)    河水与地下水水量交换模型:

式中,为极限渗漏强度;为泄流强度;为河水位;为含水层水位;为反映泥沙对渗漏孔隙淤塞情况的经验系数;为河床渗漏系数,分别为河床底部弱透水层垂向渗透系数和厚度。

(3)    地下水运动数学模型:

式中,为含水层水位;为潜水底板标高;分别为含水层渗透系数和给水度;为除河水与地下水交换量之外的其他垂向交换量;为生产井开采量;为河流识别函数。
