AR30250 Civil engineering hydraulics

Credits: 6

Level: Honours

Semester: 2

Assessment: EX100

Requisites:

Before taking this unit you must take ME20134

Aims:
* To develop the student's knowledge and understanding of open channel flow beyond that covered in Fluid Mechanics, and give the student a knowledge of civil engineering structures in which that understanding is applied.
* 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 Outcomes:
The successful student will be able to:
* demonstrate knowledge and understanding of the design of a range of open channel hydraulic structures.
* 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.
Skills:
Analytical and design skills related to the material covered.
