| Abstract: | The present report describes the results of an air and ground hydrologic reconnaissance of some 32,000 square kilometers in Sidamo Province of southern Ethiopia. Existing (1966) water resources developments, chiefly for livestock and village supplies, include surface reservoirs, a few drilled wells, several clusters of dug wells in the Mega area, several scattered springs, and the perennial Dawa Parma River. Surface-water reservoirs range from hand-dug ponds of a few hundred cubic meters capacity to large machine-constructed excavations built to hold 62,000 cubic meters of water. All the existing drilled wells tap saturated alluvium at depths of less than 120 meters. The dug wells tap water-bearing zones in tuffaceous lacustrine deposits or stream-channel alluvium generally at depths of less than 30 meters. The springs mostly rise from fractured Precambrian quartzite and individual discharges are all less than 75 liters per minute. The report also outlines the terms of reference for a longer term water-resources investigation of the region including staffing, housing and equipment requirements and other logistic support. |
