Long-term discharge and rainfall data was available al the watershed outlet and for four lest plots. In addition, 29 piezometers were installed in 2008 and water table measurements were taken duri Revised-Thesis_Final_Haimanote_formatted-22ng the main rainy season. Based on major runoff mechanisms identified at the catchment-level, a conceptual rainfall-runoff model was developed to compRevised-Thesis_Final_Haimanote_formatted-22

The model incorporates saturated excess overland flow from both bottomlands and subsoil exposed areas and baseflow and interflow from the MODELING RAINFALL-RUNOFF RELATIONSHIP AND ASSESSING IMPACTSOF SOIL CONSERVATION RESEARCH PROGRAM INTERVENTION ON SOILPHYSICAL AND CHEMICAL PROPERTIES Revised-Thesis_Final_Haimanote_formatted-22the distributed model output agreed well with the ground waler table measurements. The watershed was saturated (and produced runoff) in the flat areas near the river while the hillsides were unsaturated with a perc hed waler table that responded rapidly to rainfall.

s piece of work would never have been accomplished.My sincere gratitude goes to my major advisor Prof. Tammo. s. Steenhuis, from Cornell University, UMODELING RAINFALL-RUNOFF RELATIONSHIP AND ASSESSING IMPACTSOF SOIL CONSERVATION RESEARCH PROGRAM INTERVENTION ON SOILPHYSICAL AND CHEMICAL PROPERTIES Revised-Thesis_Final_Haimanote_formatted-22 every problem I had during my entire study and research period. He was more like a friend than just a professor.Dr. Amy s. Collick was so wonderful. She helped me organize things, gave me valuable ideas, edited my manuscript, and was always in the front line to help me during hard times. Thank you Revised-Thesis_Final_Haimanote_formatted-22so much.Very special thanks go to my co-advisor Dr. Ingr. Sileshi Bekele, East Africa Director of International Water Management Institute (IWMI), forRevised-Thesis_Final_Haimanote_formatted-22
his constructive ideas, encouragement, and worthy comments.I am thankful to ARARI, for allowing me to work at the Maybar research site and providing MODELING RAINFALL-RUNOFF RELATIONSHIP AND ASSESSING IMPACTSOF SOIL CONSERVATION RESEARCH PROGRAM INTERVENTION ON SOILPHYSICAL AND CHEMICAL PROPERTIES Revised-Thesis_Final_Haimanote_formatted-22 always generous, cooperative, and friendly. He is an amazing person with never changing smile.International Water Management Institute and Bahir Dar University are acknowledged for their financial support and Dr Ayalew Wondie helped me in facilitating the financial issues with Bahir Dar University Revised-Thesis_Final_Haimanote_formatted-22finance division.I am also greatly indebted to the technicians at Maybar Research Station: Gash All Ahmed, Seid Hussien, and Seid Belay. They were welRevised-Thesis_Final_Haimanote_formatted-22
