Modeling and Analyses of Urban Flooding in Bole Subcity System Performance and Evaluation of Possible Improvements Using Ep Swmm5

Hassen, Nejib (Addis Ababa, 2016-11)

The runoff generation in Bole area Addis Ababa is increasing due to a combination of larger rainfall intensity and more impervious areas. As a consequence several properties have been affected by basement flooding during ...
Modeling for Inter-Basin Groundwater Transfer Identification between Middle Abay River Basin and Upper Awash River Basin

Dure, Mulatu (Addis Ababa University, 2017-06)

Groundwater flow models are important for the identification of inter-basin groundwater transfer between adjacent basins. Numerical groundwater model, TAGSAC has been used to study the inter-basin groundwater transfer ...
Modeling of Sediment Yield at Kesem Dam and Identifying Soil and Water Conservation Measures

Dawit, Lenjiso (Addis Ababa University, 2019-04)

Soil erosion reduces not only soil productivity of the area but also reservoir capacity. The information on sources of sediment yield within a catchment can be used as a perspective on the rate of soil erosion occurring ...
Modeling Sediment Yield Using Arcswat And Analyzing The Most Prominent Remedial Measures: Cases of Melka Wakena Reservoir, Ethiopia

Tolosa, Dereje (Addis Ababa University, 2015-07)

Sediment accumulation in a reservoir is a serious problem that threatens sustainability of the reservoir and has severe consequence on reservoir productivity during its operation time. Therefore, this study was initiated ...
Modeling Sediment Yield, Transport and Deposition In The Data Scarce Region of Ethiopian Rift Valley Lake Basin

Alemu, Osore (Addis Ababa University, 2018-12)

Knowledge of sediment yield, transport and deposition processes taking place in a river basin is necessary to find suitable mitigation measures for reservoir sedimentation and to estimate lifespans of reservoirs. This ...
Modeling The Water Balance, Reservoir Operation and Simulation Analysis for Cascaded Hydropower Plants: A Case Study of Upper Genale-Dawa River Basin

Sora, Denge (Addis Ababa University, 2019-06)

This research is intended to assure the equilibrium between energy production and consumption from hydroelectric energy. Hydroelectric power plant development on GenaleDawa River basin is, a part of development ...
Numerical Groundwater Flow Modeling Of the Gerado River Catchment

Kidest, Ayalew (Addis Ababa University, 2018-12)

In this study, a one dimensional groundwater flow model under steady state condition was constructed as a tool to understand the aquifer system of Gerado River catchment using numerical groundwater flow modeling. The ...
Numerical Groundwater Flow Modeling of the Meki River Catchment, Central Ethiopia

Birhanu, Dereje (Addis Ababa University, 2011-10)

The Meki river catchment aquifer is located in the central Ethiopian rift valley. This unconfined aquifer is one of the most important groundwater reservoirs of the country. A total catchment of 2319 km2 was selected to ...
Operation Modeling for Tendaho Reservoir Using HEC-Ressim

Asrat, Biruk (Addis Ababa University, 2010-12)

In this study it has been intended to develop operation modeling for Tendaho reservoir using HEC-ResSim software. The input data considered for the model are daily inflow, monthly irrigation and environmental diversion ...
Operation Modeling For Zarima May Day Dam Reservoir

Biruk, Woldetsadik (Addis Ababa University, 2021-08)

The Ethiopian government is involved in the development of massive irrigation projects for sugar production in different parts of the country. One of these schemes is the Wolkayite sugar development project, located in ...
Optimal Design and Scheduling of Irrigation Pumps by Using General Algebraic Modelling Systems (Gams) A Case Study of Fentale-Qawa Pump Station

Etana, Girma (Addis Ababa University, 2015-03)

Traditionally, design engineers tend to be conservative in calculating pump station decision variables by focusing on peak demands that occur about1% of the time. On the other hand, optimal design and operation of pumping ...
Optimal Reservoir Operations on Water Resource Projects At Wabi Shebelle River Basin

Amir, Abdulhamid (Addis Ababa University, 2017-10)

Wabi Shebelle River Basin is one of the twelve river basins in Ethiopia with catchment area of 202,697 Km2 and covering parts of the regions Oromia, Harari, Somali and a small area at the source of the Wabe River in SNNPE. ...
Optimization Analysis of Water Supply Distribution System The Case Study of Awash Sebat Killo Town Distribution System

Gezahegn, Hailemariam (Addis Ababa University, 2018-10)

Water supply distribution systems estimated to account of 80 to 85% of the total cost for the whole Water supply project (International Journal of Mechanical Engineering and Technology, 2014), that include source ...
The Performance Assessment and Remedial Measures of Bridge Structure

Mandaferow, Aba (Addis Ababa University, 2019-06)
