Description
The module introduces unsteady open channel flow and sediment transport in open channels.
Aims
The aim of this Module is to provide the student with the knowledge required for solving unsteady open channel flow problems and for evaluating and predicting sediment transport rate and scouring at bridges.
Learning Outcomes
By the end of this module the student should be able to:
1. Critically analyse approaches for solving unsteady open channel flow problems.
2. Predict sediment transport rate and loads.
3. Evaluate scour at bridges.
