Ribb dam ethiopia. Gebregziabher 1, F. The Ribb Irrigation Dam is a major earth-rockfill structure designed to create a large reservoir on the Ribb River, supporting extensive agricultural irrigation in the South Gondar region. F. We inve Abstract and Figures The meandering Ribb River flows in northwest Ethiopia to Lake Tana, the source of the Blue Nile River. It is found in Amhara National Regional State, on the eastern side of Lake Tana Basin. Evaluation of small hydropower plant at Ribb irrigation dam in Amhara regional state, Ethiopia December 2021 Environmental Systems Research 10 (1) DOI: 10. 1007/s41101-022-00143-2 Authors: An earth-fill dam must be stable against seepage and slope failure for its intended function to be sustained throughout its service life. The stability of an embankment dam is determined by its shape, components, materials, qualities of each component, and thus the forces to which it is subjected. The Ribb Dam Watershed, which forms part of the headwater so urce of the Blue Nile River, is located in Ethiopia's northwestern highlands, extending from the summit of Mount Guna to the From fast-track implementation to livelihood deterioration: The dam-based Ribb Irrigation and Drainage Project in Northwest Ethiopia Author links open overlay panel Sofie Annys a b , Steven Van Passel b , Joost Dessein c , Enyew Adgo d , Jan Nyssen a Show more Add to Mendeley The Fogera Plain, Ethiopia, is affected by recurrent flooding of the Ribb and Gumara Rivers.

The newly built Ribb Reservoir fisheries, Tana Sub-basin, Ethiopia: New fishery establishment, diversity, production, challenges, and management. The irrigation area being serviced by a weir located downstream of the main dam and aimed to transform rain-fed subsistence agriculture into irrigated commercial May 23, 2022 · In Ethiopia, especially in the Tana Sub-basin, the expanded irrigation practices by building dams and weirs along the tributaries of Lake Tana did not consider fisheries nor the development and management. Location map of the study area. The project will irrigate 15,000 ha of the Fogera Plain, where the Ribb enters Lake Tana. The Ribb Dam is located on the Ribb River. The aim of this study is to apply machine learning approaches to predict design floods for the Ribb embankment dam situated in the Abay basin, Ethiopia. This study assesses the seepage and slope stability of the Ribb embankment dam. Jan 1, 2019 · Ribb reservoir is located in south Gonder zone of Amhara region, which is a multipurpose type of reservoir for irrigation, domestic water supply, and flood protection. A large dam on the Ribb River is under construction for irrigation, but also to reduce flooding. PLAXIS 2D Overall Stability Analysi s of Ribb Earthen D am in Ethiopia H. (A) Ethiopia; (B) Amhara region divided in Administrative Zones; (C) Lake Tana basin highlighting Lake Tana, Blue Nile River and Ribb River catchment; (D) studied river reach including Ribb dam, Ribb weir, Upper and Lower gauging stations, and the 2016 river centerline. It is mainly intended for irrigating a total area of 19,925 ha. Gebrehiwot 2 1 Addis Ababa Institute of Technology, Addis Ababa University, King George VI St, Addis Ab aba This paper aims to analyze the stability of Rib dam slopes under varying reservoir water levels and drawdown conditions, considering sensitivity factors and their interactions. The aim of this research was, therefore, to promote fisheries and integrate them into the irrigation systems of the Ribb Reservoir in Ethiopia. Sep 29, 2025 · Globally, the major problems related to embankment dam failures are overtopping, seepage, piping and instability due to horizontal water pressure issues. The Ribb Dam and Irrigation Development Project is a significant water resource management initiative in Ethiopia, primarily aimed at enhancing agricultural productivity and food security. The study utilized a combination of finite element and limit equilibrium methods to assess global sensitivity factors affecting zoned earth-rock . Its typical scope involves constructing a large earth-fill dam to create a reservoir, along with an extensive network of irrigation canals to distribute water to farmlands. Ribb dam is an earthen zoned dam which is located in north western parts of Ethiopia across the Ribb River, on the eastern side of Lake Tana basin, in South Gondar zone of Amhara national regional state [12]. Key engineering aspects include The Ribb Dam irrigation is one of the projects currently under construction, with a dam and a diversion weir at 77 km and 50 km upstream of the Ribb River mouth, respectively.
