To Investigate How The Nature of The Cliffs Affects The Rate of Retreat

Data required

        

  • Geology Of The Cliffs

  • The Height Of The Cliffs

  • The Volume Of Material

        

Method

The Geology of the cliff will be explained by the use of a simple diagram showing the rock composition and by a table about the different components and properties of the rocks e.g. appearance, colour, texture, hardness and permeability.

        

To find the height of the cliff we use a simple mathematical method called trigonometry. I will also compare the height of the cliff at various points with corresponding points along the beach.

The volume of material removed from the cliff is found by doing a simple calculation using data already collected, see Fig xx.

Volume Removed = Disappearing Cliff x Height Of Cliff

        To make sense of the data collected we consider some influencing factors and again compare with other parts of the beach.
