The document provides an overview of coastal erosion and transportation processes. It explains the four main types of coastal erosion: hydraulic action, abrasion, attrition, and solution. It then describes how loose materials are transported along coastlines by processes like traction, saltation, and suspension. Longshore drift is identified as the process by which waves transport sand and pebbles parallel to the shoreline. Deposition occurs when constructive waves deposit more material on beaches than they remove.
