NUMERICAL GROUND WATER FLOW MODELING OF ALAMATA SUB-BASIN IN THE RAYA VALLEY (NORTHERN ETHIOPIA)
GETACHEW WELAMO
Alamata sub-basin which is found in the Raya Valley is located in the southern
part of Tigray Regional State of the Northern Ethiopia. The area covers 51 % of
the Raya valley with area coverage of 1292.57km2. The sub-basin water
resource is used for irrigation and domestic water supply and is covered by
tertiary volcanic in western and eastern highlands and alluvial deposit in the
valley fill.
The main purpose of this project work is to make a quantitative estimation for
sustainable use of groundwater resource for domestic, live stock and agricultural
supply. To achieve this objective careful understanding of hydrology, hydrogeology
and dynamics of groundwater flow in and around the study area is mandatory.
As numerical groundwater flow models represent the simplification of complex
natural systems, different parameters were assembled into conceptual model to
represent the complex natural system in a simplified form. The conceptual model
was put into the numeric model to examine system response
