摘要

采用三维稳态模型模拟了苏丹中部努比亚含水层水文地质系统的多含水层系统。该研究的目的是检测抽水对地下水流量的影响，从而检测含水层生产力。研究区域的概念模型是在地球物理调查的指导下，根据现有的地质和水文地质数据建立的。利用MODFLOW程序对现有边界条件下的水头和水平衡进行了计算。该模型准确地模拟了水头，确定系数为0.88。校准后的模型表明，储存量的变化为0.56 m3/天，表明研究区域构成高产区，建议用于地下水开发。

Steady-state simulation of groundwater flow in Khartoum state, Sudan

The multi-aquifer system of the Nubian aquifer in central Sudan hydrogeological system was simulated using a three-dimensional steady-state model. The goal of the study is to detect the effect of pumping on the groundwater flow and thus, the aquifer productivity. The conceptual model of the study area was built based on the available geological and hydrogeological data guided by geophysical survey. Processing MODFLOW numerical code was used to calculate the hydraulic head and water balance under the existing boundary conditions. The model accurately simulated the hydraulic head with a determination coefficient of 0.88. The calibrated model indicated that the change in storage is 0.56 m3/day indicating the study area constitutes highly productive zone and is recommended for groundwater developments.
