Abstract:
The main objective of this research is to assess the available water resources
potential of Simada Wereda for sustainable development. In this paper the
annual groundwater recharge, surface runoff, groundwater returns as base flow,
spatial variability of hydrochemistry, groundwater potential zones and annual
water budget of the area were identified. Rainfall was generated using Theissen
polygon method using available data from meteorological stations, and stream
flow data was generated by down scaling the Ribb river flow data using area
ratio method. The hydrochemistry of the study area was identified using field
and laboratory analysis methods. In the laboratory major cations and anions
were identified. In terms of water quality all waters analyzed are in the
standards of World Health Organization (WHO) and Ethiopian Standard
Authority. In this work the annual rainfall, actual evapotranspiration, potential
evapotranspiration, recharge (soil moisture surplus) and the change in
groundwater flow were 1053.0mm, 667.0mm, 935mm, . and 7mm
respectively. The hydrochemistry study shows that t . '\" ;a}� v,;. J , ion in
