Learning outcomes

On the completion of this module students will

have a sound knowledge of the fundamental energy inputs to coastal processes
have an appreciation of the diversity of landforms to be found around the British coastline
be apprised of data sources that can be utilised in coastal investigations
have an awareness of the role of Man in attempting to control or manage parts of the coastal zone

Aims

This largely lecture-based module aims to introduce the physical processes operating at the coast and the range of landforms that result, as a vital background for biological or other specialists undertaking studies within the coastal zone. Lectures are initially focussed on basic energy inputs, but continue by dealing systematically with the various types of depositional and erosional features to be found in a range of coastal and estuarine sub-environments. Two further lectures then concentrate on the role of Man in managing the coast- variously looking at engineering structures which may influence physical process and form and at the role of conservation in a coastal dune environment. A supplementary handbook is provided outlining data acquisition and measurement methods appropriate to specialist investigations in coastal environments.

The course concludes with two field half-days in the local area, one appraising the beaches of Aberystwyth and the other looking at the management of the Ynyslas coastal dune system.

The introductory nature of this module is regarded as being highly suitable for both biological and physical scientists.
