The present study focuses on the analysis of physicochemical and biological water qualityrnparameters: electrical conductivity, nitrate, phosphate, COD, BOD, DO, turbidity , totalrndissolved solids, total alkalinity, total hardness, trace elements and biological parameters likernE- Coli and total...
Tekeze river basin is located in the northern part of Ethiopia. The objective of this paper is to assess surface water potential using SWAT model and estimation of water demands using the Water Evaluation and Planning (WEAP) model in the Tekeze River Basin.rnAccording to the result obtained from...
Tuberculosis (TB) caused by Mycobacterium tuberculosis is a major public health problem and continues to be a world leading killer disease primarily affecting the poor people in developing countries. The necessities of this study to provide information’s against TB about continuous...
Dam safety monitoring tool determines a functional performance of dams with anrnextended service time. One of the main dam safety monitoring tools is seepagernmonitoring system. This research presents assessment of dam safety monitoringrntechnique using seepage observed at Gilgel Gibe III...
The objective of this study is to evaluate the technical sustainability of rural water supplyrnsituation in South Wollo zone in the Amhara Regional State. The evaluation of waterrnsupply in selected rural areas is based on desk study of relevant literature and findings ofrnthe field assessment on...
Macro_ invertebrates are good indicators of human land use impacts because they arernsensitive to habitat alterations. The present study aimed at assessing the ecological impacts ofrnsediment loading on macro-invertebrates with the view to develop sediment sensitiverninvertebrate index (PSI) along...
The main purpose of the study was to make a diagnostic stUdy on the process of implementing basicrneducation in Ethiopia and detect change in the system, identify the level of the problems, the short comingrnof the system, the pressing problem which need to be solved and the area in which more...
Lake Zeway catchment is located in the northern part of the Central Main Ethiopian riftrnvalley bounded in west and north by Awash basin; and in east by Wabi shebelerncatchment. Meki and Katar are the main rivers draining western and eastern part of therncatchment respectively and both feed Lake...
A study on the abundance, distribution, feeding habit, pest status and impacts of mole rats on agricultural productivity was carried out on the farmlands of Masha during July, 2016 ─ February, 2017. Two study sites (Beto and Gembaka Kebeles) were selected based on the abundance and habitat...
In this study, Addis Ababa Water distribution system for case study of Bole Bulbula supply system was assessed. The main objective of this study is to improve the Bole Bulbula water supply distribution system and control its operation, Water CAD software was used as tool to model water distribution...
The objective of this thesis has been to investigate the possibility of tapping energy from a moving vehicle that would have been released and wasted to the ground otherwise. This has been done by designing a mechanical system to be installed across a road way such that vehicles running over it...
Nutrient dynamics plays an important role in establishment and proliferation of macrophytes in freshwater bodies. Recently Lake Tana has experienced some undesirable ecological changes due to decrease in water level, increasing trend of sedimentation and silt load(with loading rate of 8.96-14.84...
Through out history engineers have been looking for ways of designing structures that are simplernand would accurately model real life objects. In order to achieve this, actual structures have tornbe modeled in such a way that they become amenable to analysis. This was mainly achieved by...
Urban part of our country has seen a very dramatic expansions and population growth in the past two decades. Addis Ababa is one of the major city that’s affected by this expansion and population growth. Due to this the water supply demand for the city has also increased dramatically. To meet...
Erosion is a major watershed problem causing significant loss of soil fertility and productivity. Increased sediment loads that shorten the useful life of the reservoir, the lives of other water related structures, and increase the cost of maintenance and sediment remediation are off-site impacts...
Irregularities are not avoidable in the architectural design of building; however, the behavior of structures with these irregularities during earthquake needs to be studied especially for a structure with base isolation.rnBuildings with plan irregularity behave differently as compared to regular...
The main focus of this study is to see how intensity of rainfall changes in the Upper Blue Nile River Basin under the conditions of the changed climate. Predicted future climate change impacts indicate that there will be increases in rainfall, leading to an intensification of the hydrologic cycle....
This study was carried out in the eastern part of Lake Tana (Fogera Woreda) covering both postrainyrnand dry seasons, from October 2015 to April 2016, with the objective to identify and assessrnspecies composition, relative abundance, socio-economic and marketing system of fish andrnfisheries in...
Lateral load can be considered to be those which act parallel to the ground plane and may occur atrnmany angles other than perfectly horizontal generally considered to act transversally to the primaryrnstructural system. And the seismic building codes are used in analysis because of to protect...
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 heavy rainfall events when the network was severely overburdened. This thesis...
