I predicted that the pebble size at Hurlstone point will be smaller than at Gore point. Waves are longsjore and have the most energy when the wind is strong and has been blowing for a long time. The material will be eroded from Gore point which will make the beach smaller and transported by longshore drift to Hurlstone which will make a bigger beach.

This happens when the waves are full with energy. Hydraulic action also breaks off angular rocks of the cliff which is gathered on to the beach.

The longshorf bit of my investigation was to find out if the pebble shape becomes rounder as it goes from the West to East. The swash moves beach material along the beach and the backwash, under gravity, pulls the material back down the beach at right angles to the coastline.

During the weekend we also carried out a study at Minehead to analyse the coastal management. For example, the prevailing wind along the Holderness Coast is north-easterly. This leads to a lack of beach material and therefore protection for the soft, boulder clay cliffs. As the pebbles from Gore Point are moved to Hurlstone Point by long shore drift, erosion is happening.

Pebble sizes are going to get smaller going from Gore point to Hurlstone point longshord due to longshore drift, the pebbles are going to hit the sea bed as it travels from West to East so parts of the pebble will chip off making the pebbles smaller as it gets to Hurlstone.

When the waves move back, pressure is released causing the water to expand.
