DESCRIPTION - summary of the module content

There are considerable challenges in modelling the hydrodynamic, pollution and sediment transport processes in rivers, estuaries and coastal waters, primarily in terms of addressing issues relating to flood risk, coastal erosion, water quality and marine renewable energy. This course will focus on developing an understanding of the governing equations for these processes and outline numerical methods for solving these equations. You will be introduced to computational models and will apply these to solve practical problems for proposed engineering projects (such as the Severn Barrage) and to study the effect of natural and anthropogenic change,  such as climate change, population growth  and increasing urbanisation on the hydro-environment.

AIMS - intentions of the module

This module aims at introducing you to the hydrodynamics and solute transport processes in free surface flows, including rivers, estuaries and coastal waters, and to a range of numerical solution procedures of these processes. It also offers practical insight into solving these equations and processes for a range of river, estuarine and coastal basin projects.

The course will build on a traditional undergraduate course in civil engineering or similar and prior courses in hydraulics or fluid mechanics would be an advantage.
