These depositional landforms (such as beaches, sand dunes, salt marshes and mudflats) act as a dynamic sediment store and sediments are transported onshore, offshore, and alongshore to create them. The material in a sediment cell can be considered as a sediment spending plan, with misfortunes and additions. This transported material is called sediment. If the rock layers are horizontal, small overhangs of more resistant rock form in the cliff face. Around the coast of England and Wales there exist 11 sediment cells: largely self-contained sediment systems around which sediment is recycled. Sediment cells are areas along the coastline and in the nearshore area where the movement of material is largely self-contained. Sediments Fresh sediment is usually loose material that is full of open spaces, or pores, filled with air or water. Sediment is solid material that is moved and deposited in a new location. She or he will best know the preferred format. The river picks up sediment and carries it downstream in different ways.
