Potential Hafir Dam Site Selection Using GIS and Remote Sensing Techniques in Gabiley District, Somaliland
Rainwater harvesting systems have been utilized recently in Somaliland, especially in dry areas. Locating a suitable site for the rainwater harvesting structure is a decisive task for better design and planning. To guarantee water supply and to reduce the consequences of flood events, the hydrological analysis for the Hafir dam site location is done by using a geographic information system (GIS) and remote sensing (RS). The first aim of this research was thus to select a suitable site for Hafir dam construction using GIS and RS tools. The research utilized three consecutive steps to propose the suitable Hafir dam site. First, feasibility study or physical observation of the water infrastructures in ten villages of Biji and Waheen catchments in Somaliland was done. This had the plan of selecting three villages of serious water scarcity. The second step was further evaluation of the three villages to find out the most vulnerable village. The third step was to locate appropriate site of the selected village. The baseline study result showed Ijaara village to be the most vulnerable based on water scarcity. The soil type of the locations was loam, except Location 4, which has sandy soil. Based on the GIS and RS hydrological analysis, considering the catchment yield, its soil type and slope, of the four locations of the selected village, the most suitable one is located at 9.561809° and 43.637782°, latitude and longitude, respectively.
