| dc.description.abstract | Rib Dam project is located in the North-Western part of the Ethiopia, defmed by the geographic coordinate of 12° 02' 30" N and,37° 59' 45" E. The primary purpose of this dam project is to provide irrigation to 19000 hectare of land. The proposed dam height would be 54 m with a crest length of 700 m. The total storage capacity of the reservoir would be about 204 M m3 . In the present study engineering geological characterization of soils and rocks of the study area has been carried out to evaluate the dam foundation condition and the reservoir water tightness. In addition to this stability condition of the abutment and reservoir slopes has also been studied. Besides, the suitability of the construction material available in the vicinity of the project area has also been studied. The engineering geological appraisal of the dam project has been after carrying out insitu and laboratory testing on soils and rocks and determining the index and engineering properties. Geological maps of the reservoir area and the dam site has been produced at the scale of 1:25000 and I :10,000, respectively. Besides, based on the engineering characterization of rocks and soils of the area Engineering geological maps were also produced for the dam site and the reservoir areas on the scale of 1 :2000 and 1: 10,000, respectively. Thus, based on the engineering geological appraisal of the site the dam foundation area has problem of seepage at the abutments and settlement at the valley floor area. Hence certain recommendations to improve the foundation strength and seepage conditions hav~ been made. Besides recommendations on the construction material and the water tightness of the reservoir have been made. In addition, further detailed studies on the dam foundation conditions and the reservoir area have been recommended. | en_US |
