Aims: To give students a knowledge and understanding of channel flow as applied to civil engineering structures; water engineering applied to coastal, estuary and river engineering; public health engineering related to water supply, drainage and treatment.
Learning Outcomes: On successful completion of this unit, the student should be able to demonstrate knowledge and understanding of: * design of a range of hydraulic structures. * factors and relationships affecting groundwater, including replenishment, contamination and extraction. * the main factors affecting the design of civil engineering works on coasts. * factors influencing the design of hydro-electric and tidal power schemes. * the main elements of water supply, sewage disposal, and surface water drainage systems. Skills: Intellectual skills * Ability to apply the concepts and principles of fluid mechanics to the solution of engineering problems. * To understand taught material and design issues and constraints. Professional/Practical skills * To deal with civil engineering hydraulic issues in a systematic yet creative way, and to communicate the conclusions clearly. Transferable/key skills * Ability to collect, analyse, synthesise and present technical information. To demonstrate communication and team working skills.
