Abstract:

The demand of water is increasing in many regions in Vietnam, especially in the Central Highland regions where in the dry season, the lack of water resources usually causes significant problems to people’s living and agriculture. There have been many researches focusing on this area. However, the information of water - bearing structures is still limited, particularly for the local region because of a small number of projects dealing with this issue. To address this problem, in this paper, the authors implemented the 2D resistivity imaging in Cu Mga commune of Dak Lak province to determine the thickness of the weathering layer overlying the basalt, which gave important information to propose reasonable groundwater recovery plan for this local studied area. The results on 13 measuring profiles provided a detailed image of the geo - hydrological structures in the region compared to drilling and geological excavation data.
