Outline the Main Geographical Processes Relevant to Coastal Management

The main geographical processes relevant to coastal management are; attrition, abrasion, erosion, hydraulic action, corrosion and longshore drift. In order for coastal management to be successful and efficient, it must combat these geographical processes. The most common way these geographical processes are addressed is simply with a sea wall for example, the one at Manly. This then slows the rate of hydraulic action in cliff faces, driving the coastline backwards as well as the other processes. Another mangement process is the TRESB project at the Tweed River which shipped the sand moved by longshore drift back to where it was needed, slowing the rate of erosion. Abrasion and attrition can also be fought with a sea wall.
