苏丹中部的北杰济拉(Gezira)省的含水层为杰济拉含水层和白垩系含水层.在确定含水层水文地质参数的基础上,绘制了地下水水位等值线图,并通过矿化度的空间分布对地下水的化学特性进行评价.对水文地质参数的计算采用了雅各布方法和泰斯恢复水位法,通过对地下水中主要化学成分的分析来评价地下水水质,并绘制有关的水化学特性图.测得杰济拉含水层的平均导水系数和渗透系数分别为368 7m2/d和34 03m/d,均小于白垩系含水层的407 2m2/d和43 17m/d.杰济拉含水层物理化学成分的浓度明显高于白垩系含水层.白垩系含水层水质较好,适宜用作生活用水及饮用水.
The aquifer in the north Gezira province of central Sudan is the Gejira aquifer and the Cretaceous aquifer, and based on the hydrogeological parameters of the aquifer, a contour map of the groundwater level is drawn up and mineralized Degree of spatial distribution of chemical properties of groundwater evaluation.The hydrogeological parameters are calculated using the Jacob method and the Tess recovery water level method, through the analysis of the main chemical composition of groundwater to evaluate groundwater quality, and draw the water Chemical characteristics of the map Jiezila aquifer average conductivity and permeability coefficient of 368 7m2 / d and 34 03m / d, are less than the Cretaceous aquifer 407 2m2 / d and 43 17m / d. The concentrations of physico-chemical constituents in the aquifer are significantly higher than those in the Cretaceous aquifer. The Cretaceous aquifer is of better water quality and suitable for domestic and drinking water use.
