Depositional landforms include: - Beaches : Found on coasts between the high water mark (highest point on the land which the sea level can reach) and the low water mark. They form due to constructive waves depositing sand and shingle.

Objective (s): In this lab, we will use satellite maps to look at the landforms created along the N J shoreline by its longshore current as well as coastal processes in other coastal areas. 1. Describe longshore currents and their significance to longshore drift of sand. 2.
WebbGroynes are wooden or stone barries which are built at right angles to the coast. They trap material being transported by longshore drift to create larger beaches which can then absorb wave energy to reduce erosion rates. New timber groynes were installed on Swanage beach in 2005-6 and have reduced the loss of beach material.
