7530. Sedimentation Modeling (case Study Gololcha Dam Reservoir Upper Wabe Shebelle River Basin Ethiopia)
Sedimentation of reservoirs is a critical problem that jeopardizes service life of hydraulic structuresrnby reducing their active storage capacity. This investigation is intended to estimate sediment yieldrnof Gololcha dam watershed, Wabe shebelle River basin, Ethiopia and to detect the sub basins...
7531. Channel Stability Assessment And Stabilization Measure Of Mersa River Ethiopia
Channel dynamically changes in response for the variation of flow and sediment transport. rnSediment variation is because of land use change, composition of channel bank and bed materialrnwhile for variation of discharge is because of climate change, as a result channel become altered.rnThis...
7532. Assessment And Modeling Of Urban Drainage System Performance (a Case Study Of Mojo Town)
The drainage system is one of the most important factors to be considered in the urbanrndrainage infrastructure plan. Now inadequate urban stormwater drainage problemsrnrepresent one of the most common sources of compliant numerous towns of Ethiopia.rnDrainage problem in mojo town the worst issue...
7533. Studies On The Status Of Stored Grain Insect Pests Of Major Cereal Crops In Sebeta Awas Woreda Oromia Regional State Ethiopia
Cereals crops are mostly cultivate for the purpose of consumptions and commercial uses. Cereals crops also are cultivated for the industrial raw materials. The study insects pest and local community perception on their pest status in Sebeta Awas Woreda, Oromia Regional State was carried out from...
7534. Comparison Of Two Model Approaches To Investigate Hydrological Processes In Five Selected Catchments In The Upper Blue Nile River Basin Ethiopia.
The successful application of hydrologic models depends not only on the model structure, therndifferent time and space scale associated, but also on the accuracy of the simulated discharge. Thernkey issue for operational users of hydrologic models is whether physically-based...
7535. Ethnobotanical Study Of Medicinal Plants In Enemay District East Gojjam Zone Amhara Region Ethiopia
An ethnobotanical study of medicinal plants was conducted to investigate and document traditional medicinal plants and associated indigenous knowledge used to treat human and livestock aliments in Enemay Wereda. A total of 100 informants between the ages of 20 and 80 were selected to collect...
7536. Evaluation Of The Performance Of High-resolution Satellite Rainfall Products For Stream Flow Simulation (case Study Genale Dawa River Basin)
Precipitation data is the most important input parameter to simulate rainfall-runoff processes,rnsince it's strongly hooked into the accuracy of the spatial and temporal representation of thernprecipitation. In regions where rainfall stations are scarce, additional data sources could alsornbe...
7537. Predicting Discharge At Ungauged Catchments Using Rainfall-runoff Model (case Study Omo-gibe River Basin)
This paper deals with predicting discharge at ungauged catchments, the case of Omo-Gibe riverrnbasin, using the WATBAL conceptual lumped rainfall-runoff model. Parameters calibrated withrnthe model are extrapolated from gauged catchments to ungauged catchments of similar physicalrncharacteristics...
