Outline the main geographical processes relevant to Coastal Management.


For Coastal Management, closed to all geographical processes are relevant. One such process is Long Shore Drift/Transportation which is the movement of sand, due to ocean currents and diverging waves and refraction, along a single direction of the beach. The effect on coastal management is that permanent structures along the coast line can sometimes become nearer the water. This then brings in the effect of erosion along coastlines. An example of this is at Dee Why beach where a sea wall was built to replace a previous one which was destructed after storm waves and large amounts of erosion. Erosion is one of the main processes effect Coastal Management as it has one of the greatest effects along the coastline and therefore needs the greatest management. Other processes that have are relevant to Coastal Management include; corrosion, hydraulic action, abrasion, and various types of waves (ie plunging, spilling and surging waves).
