Aims & Learning Objectives:
Aims:
To give the students some knowledge and understanding of Water Engineering applied to coastal, estuary and river engineering.
To give the students a knowledge of Public Health Engineering including water supply, drainage and treatment.
Learning objectives:
The succesful student should be able to:
* demonstrate knowledge and understanding of the factors and relationships affecting groundwater, including replenishment, contamination and extraction
* demonstrate knowledge and understanding of the main factors affecting the design of civil engineering works on coasts
* demonstrate knowledge and understanding of the application of open-channel hydraulics to river and canal engineering
* demonstrate knowledge of the factors influencing the design of hydro-electric and tidal power schemes
* demonstrate knowledge and understanding of the main elements of water supply, sewage disposal, and surface water drainage systems.
