Remote Sensing Based Assessment of Water Resource Potential for Lake Tana Basin

Daniel, Yohannes (Addis Ababa University, 2007-04)

1. Remote sensing techniques have been applied to augment estimation of hydrologic variables. Thus rainfall, evaporation, flooded zone delineation and runoff estimation has been carried out. TRMM monthly rainfall products ...
The Effect of Topography on Rainy season Rainfall Variability over Blue Nile River Basin

Habte, Shambel (Addis Ababa University, 2013-05)

The effect of topography on rainfall variability in the East Africa highlands is less studied rainfall processes. 37 rain gauges and 5 complete weather sensors along four transects in the complex terrain region of the Blue ...
Prediction of Soil Water Characteristic Curve Based on Gsd and Pi for Red Clay and Expansive Soils Found In Addis Ababa

smail, Nuru I (Addis Ababa University, 2013-08)

Many researchers have done researches on unsaturated soil mechanics worldwide to bring the unsaturated soil mechanics in to practices. Among those researches some of them focused on simplifying the complex and expensive ...
Error in High–Resolution Satellite Rainfall Products in Streamflow Prediction in Birr Watershed, Ethiopia

Solomon, Nebiyu (Addis Ababa University, 2013-05)

The main objective of this study is to evaluate the performance of high – resolution satellite rainfall products (TMPA 3B42RT, 3B42V6, and 3B42V7) under sparse ground based data and complex topography medium sized watershed ...
Development of Synthetic Unit Hydrographs for Watersheds In The Upper Awash and Upper Tekeze Basins

Azeze, Mulugeta (Addis Ababa University, 2004-10)

Hydro-meteorological data are very indispensable for the assessment and development of water resources. However, most catchments in Ethiopia are ungauged and direct streamflow observations are not available at most sites ...
Flood Generated from Tana Lake Basin

Tamiru, Mossie (Addis Ababa University, 2008)

The computation of runoff usually consists of applying a stage- discharge relation to daily gage heights to determine mean daily discharges. However, for this particular study a hydrologic model, HEC-HMS is applied to ...
Ensuring Functional Sustainability of Water and Sanitation Developments in Rural Areas (Southern Ethiopia)

Israel, Fiseha (Addis Ababa University, 2014-04)

Ensuring functional sustainability of water and sanitation developments throughout the design period is vitally necessary. It helps to identify the main causes of non functionality and indicate the troubleshooting for ...
Comparison of Pseudo-Static and Dynamic Response Analysis of Sibilu Dam

Getachew, Fantahun (Addis Ababa University, 1979)

Dynamic loads induced by earthquakes are often major factors in the design of earth dams. Earthquake induced stresses are major factors in determining the angles of the dam slopes and significantly influence the selection ...
A Study of Flexural and Compressive Strengths of Jute Fibre-Reinforced Concrete

Bantie, Enyew (Addis Ababa University, 2010-03)

The problems associated with low efficiency in tensile strength of structural elements, brittle mode of failure, rapid crack propagation and increased overload are common in the concrete construction industry. Whereas ...
Water Use and Operation Analysis of Water Resource Systems in Omo Gibe River Basin

Asefa, Daniel (Addis Ababa University, 2011-05)

In this study, HEC-ResSim (Hydrologic Engineering Center-Reservoir System Simulation) model was used to simulate water use and operation of existing, ongoing and planned hydraulic infrastructures, and irrigation schemes ...
