摘要

地下水是西奈省Ras-Matarma地区淡水的主要来源，需要对其进行优化管理。在此背景下，进行了地球物理地磁、斯伦贝谢电阻率反演、遥感(RS)、地理信息系统(GIS)和抽水试验。磁测包括56条剖面，而斯伦贝谢电阻率测量包括27条VES。利用GIS和RS技术对流域进行分析。磁资料解释将浅部构造与深部构造明显分离，深度在300 ~ 1400 m之间。反演电阻率数据的定性和定量建模有效地圈定了真实电阻率和厚度为22 ~ 210欧姆的新含水层。M和2 ~ 80m。GIS综合了上述所有结果以及新鲜含水层的电气和水力参数。

Magnetic and Geo-electrical Geophysical Techniques for Subsurface Delineation and Groundwater Assessment in Ras Matarma, Sinai

Groundwater constitutes the main source of the freshwater in Ras-Matarma, Sinai, which necessitates optimized management of it. In this context, geophysical ground magnetic, Schlumberger resistivity inversion, remote sensing (RS), geographic information system (GIS), and pumping tests were conducted. The magnetic survey comprised 56 profiles, whereas, Schlumberger resistivity survey were 27 VES. GIS and RS were implemented for watershed analyses in the area. Interpretation of the magnetic data separated significantly the shallow and deep structures with depths ranged from 300 to 1400 m. Qualitative and quantitative modelling of the inverted resistivity data demarcated effectively the fresh aquifer with true resistivity and thickness ranged from 22 to 210 ohm.m and 2 to 80 m, respectively. GIS aggregated all the aforementioned results along with electric and hydraulic parameters of the fresh aquifer.
