Integrated Hydrological Analysis of Little Akaki Watershed Using SWAT-MODFLOW, Ethiopia

In Ethiopia, groundwater is the main source of freshwater to support human consumption and socio-economic development. Little Akaki watershed located in Upper Awash basin, known for its high annual rainfall considered as potential recharge zone. On contrary, urbanization industrial expansion are increasing at an alarming rate area. This became a concern threatening resources’ sustainability. To address these challenges, integrated analysis numerical simulations were made. For estimation, SWAT model was used. The result indicated that mostly occurs from July October with maximum values August. average, estimated catchment 179 mm. simulation prediction flow system, MODFLOW 2005 head converges towards river and, finally, outlet watershed. study areas interactions between groundwater. scenario examination reveals present pumping by over fifty percent (by 50%, 100%, 200%) will surely cause visible decline near watershed, substantial baseflow reduction. reduction also indicates huge risk sustainability
