Stochastic Simulation of Streamflow and Hydrologic Drought Analysis (Case Study: Upper Blue Nile Basin

Hagos, Yohannes (Addis Ababa University, 2009-06)

This thesis is concerned with the problem of stochastic simulation of streamflow and hydrological drought analysis in the upper Blue Nile basin ( Abbay).Thirteen stations with long record period ranging from 35 to 45 years ...
Stream flow Simulation for The Upper Awash Basin.

Behailu, Shimelis (Addis Ababa University, 2004-07)

The Awash Basin is the most utilized and most developed basin in Ethiopia. After the construction of the Koka dam the feature of the basin is changed in large extent. Heavy rainfall in the upstream catchments causes large ...
Study of Index Properties and Shear Strength Parameters of Laterite Soils in Southern Part of Ethiopia the Case of Wolayita - Sodo

Tibebu, Hanna (Addis Ababa University, 2008-05)

Most geotechnical problems such as bearing capacity, lateral earth pressure and slope stability are related to the shear strength of a soil. The shear strength of a soil can be related to the stress state of the soil. ...
A Study of Movement of Igs Stations Due to Effect of Hydrological Water Loading Using Gps And Grace Data (A Case Study of East Africa)

Mchila, Bakari (Addis Ababa University, 2013-07)

This thesis studies the movement of GPS (IGS) stations due to elastic surface deformation of the earth caused by hydrological water loading as detected by the combined monthly Gravity Recovery and Climate Experiment ...
Surface Irrigation Suitability Analysis of Southern Abbay Basin by Implementing Gis Techniques (A Case Study in Dedessa Sub-Basin)

Tariku, Meron (Addis Ababa University, 2017-02)

The study aims at evaluating physical suitability (land and water resource) for surface irrigation development using GIS techniques. The Dedessa sub-basin was selected as a case study for this thesis work. The Dedessa ...
