Geological, Soil and Rock Mass Evaluation for Proposed Hydroelectric Power Plant at Sennar Dam, Sudan

M.A.M. Ez Eldin, Tang Huiming, N.H. Bahwi and A.G. Faraw

Abstract:
A feasibility study by using geological, geotechnical and geophysical investigations (VES and seismic refraction) have been carried out for construction a new hydroelectric power plant at Sennar Dam situated at Sennar State, 350 km south of Khartoum (the capital of Sudan). As a consequence of the completions of the development projects and increasing demand for more energy due to rising population, a recommendation have made to construct a new hydroelectric power plant in the proposed site. Sennar Dam is a masonry gravity dam sits on teschenite-gabbro rock foundation across the Blue Nile, 45 m in height and over 3 km in length. For this study, the depth of soil and rocks, thickness, geological discontinuities, boundaries and geotechnical properties were determined. The drilled boreholes data has revealed shallow depths of soil. The laboratory test of soil samples showed intermediate geotechnical properties. The study suggests that the Proposed Hydroelectric Power (PHP) plant can be constructed directly on the slightly weathered or fresh teschenite-gabbro bedrock to a depth of not less than 10 m.
