1
The Erosion Threat Aims: To understand the physical and human factors that cause the Holderness Coast. To know there are variations in erosion rates. To know why the construction of dams cause erosion.
3
The geology is key to understanding why
locations such Flamborough Head stick out as a ‘headland’ = resistant rock type along the coastline there is less resistant rock which is easily removed by the waves and transported as longshore drift
4
Coastal protection
5
Hornsea coastal protection
Withernsea coastal protection Easington coastal protection Mappleton coastal protection
6
State the physical factors that are causing some coasts to recede faster than others.
7
How do human actions interfere with the sediment cell and give a named example as part of your answer Bottom of p134 and top of 135
8
Under the variations in erosion rate – p135
Using a named example, explain why erosion rates vary in time and space on a stretch of coastline Under the variations in erosion rate – p135 Many factors to add here from the Holderness coast
9
Why did the construction of the Aswan High Dam on the River Nile cause sediment volume to fall?
p136
10
Describe and explain how the Akosombo Dam in Ghana has reduced sediment and increased erosion.
11
Briefly describe how a coastlines erosion can be measured
Briefly describe how a coastlines erosion can be measured. You may bullet this detail with older methods and new technology. Skills focus – p137
12
Looking at the maps 10.11, describe the differences between 1940 and 2015
Skills focus - 137
