1. When waves approach an irreegular coastline, they are refracted and become increasingly parralel to the coastline
2. The part of the wave that is still in deeper water moves faster causing the wave to bend around the headland. Wave energy becomes concentrated on the headland - causing greater erosion
3. The low energy part of the wave spills onto the beach causing deposition. As waves pile against the headland, there may be a slight rise in sea level that results in long shore currents from the headland, moving some of the eroded material towards the bay, contributing to beach build up.
