12129. Evaluation Of The Performance And Cost Of Pavement Marking Materials The Case Of White Lane Line Marking In Addis Ababa City Arterial Streets
Most Addis Ababa City arterial streets furnished with inappropriate faded pavement markings which increase the exposure are road users for the accident. Understanding the durability performance of pavement marking material over time is important to establishing an optimum pavement marking strategy....
12130. Studies On Voltage Control Of Distribution Substations Using Static Var Compensators (case Study Addis Ababa Kality Ii 13215 Kv Substation)
Voltage control of power distribution systems is very important to ensure quality power supply to the customers. The potential applications of flexible AC transmission system (FACTS) devices, such as the Static Var Compensators (SVCs) play a major role in voltage regulation due to its fast response...
12131. Assessing Transmission Line Loss In Ethiopian Electric Power System Under Contingency Conditions
Ethiopian Electric Power (EEP) is comprised of large interconnected power systems with far apart and geographically remote generators and loads connected by long transmission lines. This results high transmission line loss and transmission line contingencies frequently. Contingency of any one of...
12132. Study And Evaluation Of Lightning Over Voltages For Protection Of Transmission Lines Case Study Of Gerd-diddesa-holeta Transmission Line
Lightning is one of the most significant sources of over voltages in overhead transmission lines. The lightning over voltages could lead to failure of the devices connected to the transmission line. A fundamental constraint on the reliability of an electrical power transmission system is the...
12133. Dam Heightening (case Study Gefersa-iii Dam)
Sediment problem is a major problem which highly reduces the live storage capacity of the reservoir. Gefersa-I/II dam is one of the major embankment dams in our country Ethiopia which trap huge amount of sediments in each year. Due to this reason AAWSA decide to heighten the existing dam up to 5m...
12134. Evaluation Of Global Water Resources Data Products For Local Water Management Application In The Upper Blue Nile Basin In Ethiopia
Under the condition of water scarcity and competing water uses, improved knowledge of basin wide hydrology is pivotal for various water resources management and applications. Availability and quality of hydro-meteorological data sets determine understanding of the hydrology and sustainable planning...
12135. Planning And Operation Of Hydropower Reservoir In Tekeze Basin Considering Hydrological Variability And Climate Change
Reservoirs are built to manage surface water resources used to balance between water resources and demands. Water in the arid, semi-arid and other climate regions like Ethiopia has available finite, but the demand increases. Hence reservoirs should be optimally operated in this semi-arid area to...
12136. Evaluate The Effects Of Watershed Characteristics On Stream Flow The Case Of Blue Nile River Basin Beshilo Watershed Ethiopia.
Land degradation is a series problem in Ethiopia highlands, particularly in Blue Nile River Basinrnreflected in the form of soil erosion and soil fertility decline from time to time. Beshilo watershed isrnone of the major Blue Nile River Basin tributary, which covers 5,700 km2. The effect of...
12137. Simulation Of Oedometer Test Using Finite Element Method
One-dimensional consolidation test is one of the commonly conducted laboratory tests used to determine the stiffness and compression properties of fine grained soils. Study on predicting bearing capacity and compressibility of clay soils is still attracting interests of geotechnical researchers....
12138. Assessment Of Potential Groundwater Zone Using Integrated Gis And Remote Sensing Techniques In Sekota Wereda Northern Ethiopia.
