Downstream Consequences of Ribb River Damming, Lake Tana Basin, Ethiopia

Chalachew Abebe Mulatu was born in Dangila, Ethiopia, in 1977. He obtained his B.Sc. degree in Hydraulic Engineering from Arba Minch Water Technology Institute, Ethiopia, and M.Sc. degree in Water Science and Engineering, specialization Hydraulic Engineering and River Basin Development, from UNESCO-IHE, Delft, the Netherlands. His Ph.D. research work focuses on the effects of dam construction on the downstream river system, focusing on the Ribb River, Ethiopia. He has been working for more than 16 years in different governmental and non-governmental organizations in Amhara Region, Ethiopia, mainly on capacity development, and as a team leader and design, engineer to study and design water resources projects. In May 2009, he joined the Faculty of Civil and Water Resources Engineering, Bahir Dar Institute of Technology, Bahir Dar University in a position of lecturer. He has been the Director for the school of Civil and Water Resources Engineering from October 4, 2011, to December 24, 2012. He teaches Hydraulic Structure-II and Embankment Dam Engineering for Postgraduate Hydraulic Engineering students, and hydraulic structure-I and II, and hydropower development for an undergraduate student. He has been the main advisor for two M.Sc. students in river morphology and sediment transport. Moreover, he is a co-founder of KIM FC Water Works Consultancy PLC, registered in Category Five, which provides engineering consultancy services in study, design, and construction supervision of Irrigation and water supply systems since 2011. His research interest includes sediment transport and river morphology, flood modeling, and water resources management and modeling.
