DIVERSION WEIR DESIGN PROJECT FOR (ASHER RIVER [article]

FELEKE GURMECHA
2017
The purpose of this design diversion head work structure is to present the final result. Hence, it discusses the analysis of hydrology, hydraulic and structural design of the headwork and also presents bill of quantity and cost estimation are stated. This Study involves collecting data from different sources and using flow magnitude estimation method identifying maximum irrigable area which is 140 hectares, analyzing data, and changing the rainfall data to runoff using complex hydrograph

Ogee types of weir is selected in order to dissipate the higher energy due to higher discharge. In additional part of the project based on the peak discharge design components of each hydraulic structure, under sluice, head regulator, stilling basin and divide wall. The structural of weir safe due to different load conditions. Besides, Type I stilling basin is selected.
