Water Engineering 1

Description

Overview: To introduce design calculation methods in water engineering and hydrology. To be able to perform design calculations for uniform channel flow and for steady flows in pipes and in pipe networks. Perform design calculations in engineering hydrology, to develop competency in calculations for the unit hydrograph, flood frequency analysis, reservoir routing. To have an understanding of the geological controls on groundwater resources and groundwater flow. Syllabus: Boundary layers, shear flows Pipe flow ? Stanton & Moody diagram Flow and pressure distribution in pipes and pipe networks Frictional head loss in pipes including part-full pipes Pipe network analysis Flow and pressure distribution in pipes and pipe networks Pipe network analysis Uniform flow in channels - Manning?s equation Hydrology: Groundwater; the Unit Hydrograph; reservoir routing; flood frequency analysis. Flooding and flood prevention. Learning Outcomes: Understand significance of Manning n value & concept of resistance in rivers and channels.
