An explanation of longshore drift and how it is affecting one farm in Holderness on the east coast of England. A group of children conduct an experiment to see how longshore drift works. Longshore drift is where particles of clay are transported down the coast. The particles are finally deposited further down the coast and new land is formed. The coastline is therefore always changing. The seaside town of Withernsea in Yorkshire uses coastal protection in the form of a large sea wall and groynes. This is known as a hard point.
