WebHydraulic Action Hydraulic action is the first type of coastal erosion that occurs when destructive waves that strike a cliff face compress air found in the crevices of these cliffs. The pressure exerted by the compressed air erodes the surrounding rocks, causing sediment and materials to break off. Abrasion WebThere are four main processes of coastal erosion.
