The investigated region is located in the western desert fringes of the Nile Valley which requires studies of groundwater related to the many projects of land reclamation. The key objective of this paper is to estimate the qualitative and geometrical features of the investigated aquifer. Using 60 vertical electrical sounding and time-domain electromagnetic soundings allows us to suggest one possible model of the geometrical features of the local aquifer. A hydrogeological monitoring has been undertaken to investigate the current groundwater situation at the Gallaba plain. Such hydrological monitoring has not been undertaken before in detail. The results show that the investigated region has high groundwater potentialities in two main aquifers which belong to Pleistocene: shallow fresh water and deep brackish water. The lithological and structural elements contribute mainly to recharge and store the groundwater in the western part of the River Nile in Kom Ombo graben. The geochemical properties of the groundwater of the studied aquifers reflect meteoric water, which is a fresh to slightly brackish water. The small amount of groundwater salinity arises from silicate weathering and evaporation processes occurring in the aquifer matrix. Moreover, most of the studied groundwater samples are unfit for human consumption. Such samples are very satisfactory for livestock and poultry purposes and they can be used for irrigation using modern and improved irrigation methods e.g. sprinkler and drip methods. Furthermore, the hydrogeological monitoring of the concerned area indicates that it has high groundwater potentialities which will support its sustainable development.

利用地球物理和水文地质数据评估埃及西部沙漠加拉巴平原的地下水分布

调查区域位于尼罗河流域西部沙漠边缘，需要对与许多土地复垦项目相关的地下水进行研究。本文的主要目的是估计所调查含水层的定性和几何特征。使用 60 次垂直电测深和时域电磁测深使我们能够提出当地含水层几何特征的一种可能模型。已进行水文地质监测以调查加拉巴平原当前的地下水情况。这种水文监测以前没有详细进行过。结果表明，调查区在属于更新世的两个主要含水层中具有较高的地下水潜力：浅淡水和深咸水。岩性和构造元素主要用于补给和储存康翁布地堑尼罗河西部的地下水。研究的含水层地下水的地球化学性质反映了大气水，这是一种淡水到微咸水。少量地下水盐度来自含水层基质中发生的硅酸盐风化和蒸发过程。此外，大多数研究的地下水样本不适合人类食用。此类样品非常适合用于牲畜和家禽用途，它们可用于使用现代和改进的灌溉方法（例如喷灌和滴灌法）进行灌溉。此外，
