CENV6126 Coastal Morphodynamics

Module Overview

Coastal morphodynamics is the study of coastal geomorphology and its change under the influence of waves, tides, etc. It is important to understand coastal morphodynamics as natural coastal geomorphology such as beaches provides substantial protection and this needs to be monitored and evaluated. Further, there is increasing interest in soft as opposed to hard approaches to coastal engineering that are inspired by natural geomorphic systems. This module introduces the students to: • The concepts of coastal morphodynamics in a range of settings and regimes, with an emphasis on beaches and the UK situation; • Methods for analysing and predicting coastal change; and • ‘Soft’ approaches to coastal engineering and management. This includes consideration of basic sediment and morphological theory, analytical and numerical models, and relevant contemporary issues, such as shoreline management planning and impacts and responses to sea-level rise.The course comprises a series of lectures and workshops, with one field trip.

Aims and Objectives

Module Aims

To introduce you to concepts of 'soft' coastal evolution in a variety of settings and regimes, and its application to predicting future coastal change as well as soft approaches to coastal engineering, especially beach nourishment. This will include theory, analytical and numerical models, and current issues, such as shoreline response to sea-level rise. The course will cover theory, analytical and numerical models, and current issues, such as shoreline response to sea-level rise.
