Geophysical Exploration for Groundwater Resouces Potential over Basement Formations at Kwandolwa And Mwisho Wa Shamba Villages, Korogwe Distict, Tanzania
Abstract
In this paper results of geophysical exploration studies to identify potential areas with groundwater resources at Kwamndolwa and Mwisho wa Shamba Villages in Korogwe District have been presented. The resistivity curves of eight sites at the two study areas were obtained using field data measurements made based on the application of a vertical electrical sounding (VES) method. The resisivity values obtained for sites VES-K3 and VES-M2 were found to be 10.9 and 24.0 ohm-m respectively. The interpretation of the resisivity values made for the two sites gave also an indication of the presence of sedimentary rocks composed of sandstone materials at the basements, known to constitute a good water bearing potential. These results are to be used as a guideline for borehole siting, providing information on the depth to the groundwater relevant to the development of effective water supply schemes at the study areas. Verification of the exact quality of water will be obtained during drilling tests
