Holderness + Tees

Question 1

Locational information on holderness

Answer 1

Holderness coast is an area in Yorkshire, on the NE coast of England
Stretches from Flamborough head to the Humber Estuary
It is the fastest eroding coastline in Europe, averaging 2m a year

Question 2

Mappleton erosion

Answer 2

In 1991, £2million was spent on two rock groynes to protect the B1242 coastal road and Mappleton
Blocks of granite imported from Norway, maintaining a wide, Sandy beach to prevent destructive waves from reaching the cliffs
Erosion has been reduced from 2metres to 1metre

Question 3

Aldborough erosion

Answer 3

Was 1m now 2.5m
Due to destructive waves having less sediment, so they have much more force, rather than constructive waves
More hydraulic action
Over 10,000 properties are now at threat because of this

Question 4

River Tees locational

Answer 4

Located in NE England
Source is high in Pennines and river flows eastwards into the North Sea
Source of the River Tees lies in cross fell, 893m above sea level

Question 5

Mandale Loop

Answer 5

In 1810 the Mandale Loop was cut off, shortening the river by 4km
This meant less energy is wasted by meander and flow of water is faster, made it easier for trade

Question 6

Cow green reservoir

Answer 6

In 1970 Cowgreen reservoir was built which can hold 41million cubic metres of water
It meant that we could monitor the rate of water flow
At high water level, we will have higher erosional capacity, we can reduce flow to prevent this
At low water level, we will have blockages of sediment due to low energy of water, can change this to a continuous flow

Question 7

River Tees Barrage

Answer 7

Cost £55million
Provides leisure activities
Prevents flow of sediment by storing it at the bottom of the barrage
Storm events + reduced flooding
