Identification of suitable sites for artificial water tanks in Adigrat town through GIS and remote sensing technique
The Adigrat town sometimes faces a severe shortage of water; this is primarily due to maximum runoff of rain water and lack of water conservation practices. In this study, an attempt is made to identify suitable sites for artificial water tanks for water conservation and augmentation of groundwater through a combination of GPS surveying and GIS based hydro-geomorphic approach in Adigrat town. GPS survey was done to know the magnitude of the problem. Hydro-geomorphological characteristics of Adigrat drainage basin were studied using ASTER data. As a result fourteen sites were identified suitable for artificial water tanks in Adigrat town. These sites were identified on the basis of water accumulation, stream channels order, water need assessment, underground water, rock types. The study will helps in designing a suitable water management plan and flood control for Adigrat town.
