The Holderness Coastline

The infamous Holderness Coastline is located on the East coast of

Yorkshire, stretching from Flamborough Head to Spurn Point. In the

last 2000 years the coastline has retreated by almost 400m and since

Roman times over 28 villages have disappeared into the sea between

Bridlington and Spurn Head. About a million years ago the Yorkshire

coastline was a line of chalk cliffs almost 32km west of where it now

is. During the Ice Age deposits of soft boulder clay were built up

against these cliffs to form the new coastline. It is this soft sand

and clay which is easily eroded by the action of waves, as the ocean

slowly claims back the region it used to occupy.

There are several factors which have resulted in this region

experiencing one of the fastest rates of erosion. One already

mentioned is the material which is being eroded, or the geology of the

land. The boulder clay deposited 20,000 years ago as a result of the

last retreating ice age is a soft rock of little resistance. Although

it also cannot quite be classed as a rock as the process of diagenisis

has not been completed (the transformation of sediment into a

sedimentary rock) classing it as an 'unconsolidated rock'. This

boulder clay is also impermeable, holding water it its pore spaces.

This causes heavily water logged sea cliffs, which often results in

rotational slumping as the saturated cliff face slides forwards onto

the beach, and is eroded away. In some places the clay cliffs are

eroded as fast as 6 metres per year, but the average is 1.8 metres per

year, which is ten times greater than that of chalk. Regions where

erosion is at a fast rate, it i...

now only a few feet. The loss of the Gas Terminal would result in the

loss of hundreds of jobs and the loss of a very expensive structure.

This would cause a great change upon human activity in the area, and

there seems little that can be done to economically protect it.

Land and house prices along the coastline have fallen dramatically,

and some people have opted to pay thousands to have their houses moved

back from the coastline to savour at most a few more years' occupancy.

The overall population of the area is falling, as there are few

attractive prospects to either keep existing people there or attract

new people.

Many businesses are losing out, as tourism in the region decreases, so

does income, and therefore profit. This is affecting shops, holiday

parks, and hotels.
