AIMS

This module aims at providing a solid framework of knowledge required for the proper management of coastal erosion. Reference is made to integrated coastal management and how coastal erosion is embedded in it. Thus the contents of this module support the formation of a primary tool for coastal engineers and other scientists in applying planning and other managerial interventions to the coastal zone respecting the principles of sustainability.

INTENDED LEARNING OUTCOMES

1. Subject Specific Knowledge, Understanding and Skills

By the end of this module, the students should:

• be able to specify coastal zones and to identify coastal erosion as a prime factor in the framework of integrated coastal zone management;
• be able to identify and understand the basic properties of the main environmental factors playing a role in coastal erosion;
• understand the physical processes related to wind wave generation and shoreward propagation; coastal currents and long waves; sediment transport in the coastal zone.
• Have acquired basic knowledge and understanding on coastal geomorphology, including estuaries;
• be able to identify and initialise the layout of possible interventions, including mild ones, to prevent coastal erosion;
• understand the main factors and processes underlying coastal flooding;
• acquire basic information regarding the European coastal zone management perspective.

2. Core Academic Skills

By the end of this module, the students should:

• be able to identify, formulate and analyse coastal erosion problems;
• be able to propose interventions toward solving coastal erosion problems;
• have acquired a sound understanding of the impact of coastal erosion on the integrated coastal erosion management;
• have acquired some practical experience in using simple modelling techniques related to coastal physical processes.

3. Personal and Key Skills

By the end of this module, the students should have:

• improved further the necessary skills for independent learning;
• enhanced reporting skills;
• improved some IT skills.
