江苏姜堰孔隙承压地下水资源评价三维数值模拟

3D numerical simulation for confined groundwater resource evaluation in pore aquifer sediments in Jiangyan of Jiangsu

通过建立符合该地区承压地下水赋存条件和渗流特征的地下水三维数值模型,并在模型识别、验证的基础上,根据各承压含水层的水位控制要求,调整现有地下水的开采布局,以乡镇为单位,确定出各含水层的地下水可开采资源量及最优开采布局,并预测2011—2020年底逐年地下水水位动态变化情况。

The authors established a three-dimensional numerical model according to the hydrogeology occurrence and seepage condition of the pore confined aquifer in the loose Quaternary sediments in Jiangyan of Jiangsu Province. Based on the validation and verification of this model,the current exploitation pattern was adjusted for better control of the water level for each aquifer. Then the exploitable quantity of groundwater and the optimal exploitation pattern were determined for the towns and villages. A prediction of the dynamic change of the groundwater level from the year 2011 to 2020 was also made.
