The meandering Ribb River flows in northwest Ethiopia to Lake Tana, the source of Blue Nile River. river has already undergone changes due several human interventions, such as embanking, sand mining, water extraction and lake level regulation for hydropower. At present, a dam weir are under construction store divert irrigation. This will strongly alter both sediment discharges downstream reaches, causing adjustments morphology. Assessing current morphodynamic trends is first necessary step...
Abstract The water–energy–food–ecosystems (WEFE) provide vital resources that are essential to human existence. Exploring synergies and trade-offs in these systems has been of interest recent years increase economic gain while sustaining the environment. Tana-Beles Sub-basin Ethiopia is challenged by population density, climate change, ecosystem degradation requires a WEFE Nexus thinking. To understand current nexus interactions basin, systematic review 102 scientific research articles...
This work investigates the applicability of an analytical method for quick assessments long-term morphological effects different dam operations on downstream river reaches with idea to apply in feasibility studies identify least morphologic-impacting operation scenario. The Ribb River (Ethiopia) is used as a study case. estimates idealized, new equilibrium bed profile without considering duration evolution. We distinguishing sand-bed from gravel-bed reaches. outcome compared that calibrated...
The Fogera Plain, Ethiopia, is affected by recurrent flooding of the Ribb and Gumara Rivers. A large dam on River under construction for irrigation, but also to reduce flooding. We investigated effects flood regime floodplain wetlands using a combination hydrodynamic rainfall-runoff models. model was calibrated based inundation maps retrieved from Landsat images. Pre- post-dam comparison 10 years shows that will extent 11%, as it only regulates 23.8% upstream watershed. duration necessary...
