  1. The Impacts of Water Infrastructure Development on the Hydrology and Water Resources of the Omo-Gibe River Basin Advisors Prof. Murugesu Sivapalan (University of Illinois, USA) Prof. Alma Lopez-Aviles (AAU, ETH) Dr. Macalister Charlotte (IWMI, ETH) Dr.Ing Dereje Hailu (AAIT, ETH) By Adanech Yared PhD Student

  2. OBJECTIVE OF THE RESEARCH Main objective • The major objective of this research is to characterize and quantify the impacts of water infrastructure development on the hydrology and water resources of the Omo-Gibe River Basin. Specific objectives • To characterize and quantify natural, current and future flow regime in • the Basin. • To detect long-term monotonic trends and step/abrupt changes in stream • flow resulting from ongoing infrastructure development. • To identify different downstream major demands in the Lower Omo River • Basin below the weir proposed to large scale commercial farms and to • allocate water for identified major demands. • To propose suitable operating flow regimes.

  4. Materials and methods (methodology) • Material to be used • ArcGIS 9.3 • R-Software • IDL • HBV model • GAMS or Goal Programming • Water Evaluation And Planning System (WEAP) Methods/Methodology • Naturalizing stream flows • By using WEAP model will be do four scenarios Scenarios to be used • historic scenario from 1977-2000 • Existing period scenario 2012 • Medium period scenario from 2013-2015 • Long period scenario from 2016-2025 • Other primary and secondary data analysis • Flow modeling • Impact analysis WEAP Setup • Challenges • Limitation of data
