What is it?
Coastal erosion is the specific form of wind erosion which damages coastal sand dunes. The sand dunes have little material less than 0.1 mm diameter and thus dust movement is rarely associated with this form of erosion. Loss of vegetative cover by over use of such areas allows wind to destabilise the dunes.
