Transcript of How long will Happisburgh hang on?

By Tara Loosmore and Lucy Hong Happisburgh Problems and Solutions
in Happisburgh Factfile about Happisburgh:

Where?: North Norfolk
What?: English village and civil parish
When?: Had its first recorded habitants over 800,000 years ago
Area?: 10.78km squared
Population?: 1372 people in 2001 Census
However, Happisburgh is facing a huge problem - the fact that over time, the sea has slowly eaten its way into the coast. This is a dilemma for the habitants, as the sea could eventually break down their houses. Introduction Happisburgh is being faced with severe erosion, and many houses which used to over 20m feet away from the sea are now sitting on the edge of the cliff.
Beach road (which leads to the sea) is being constantly eroded.
Large sections of the sandy cliffs are being broken down and are falling into the sea.
The waves have a long fetch and are very powerful as there is no land nearby. The fetch to Norway is about 1500 km.
Global warming has increased sea level and this increases the power of the waves. Problems Sea walls can be built to stop the waves reaching the valuable land.
A barrier of rock armour (big rocks) can soak up the wave's energy, which means less erosion.
You could build a reef of rocks out at sea, so the waves break away from the beach.
Add more sand to the beach (to build it up), and this is called 'beach replenishment'.
Groynes stop sand being taken away, as the sand absorbs the waves' energy.
Wooden revetments get battered by the waves instead of the cliffs. Solutions They coast monaaay (coast? geddit?)
All of these possible solutions have one thing in common - they all need money to be funded and made.
Government policies now limit funding for coastal protection, so councils do not have that money and the resources needed to make defences, thus Happisburgh is still in grave danger.
However, wooden sea defences were made before (in the 1950's), but over time, they have been destroyed by the sea and wind. As we mentioned before, the government have limited coastal funding. There are also many other places which are being eaten up by the sea, and they all want sea defences that are appropriate. This is a HUUUUGE problem for the government as they can not pay for all of the defence.
So how are the Government coping with this?
They decided to only fund places with the largest population and tourism attractions.
What about Happisburgh?
Sadly :'( Happisburgh is not one of the places chosen to have sea defences put up. It is only a small village with a population of approximately 850. Funding problems 1. Where is Happisburgh situated?
2. What is the fetch from Norway to Happiburgh? (in km)
3. What stop sand from being taken away from beaches?
4. When were the last sea defences made?
5. Why does Happisburgh not have sea defences put up? Quiz :) Problems with the Solutions Happisburgh on the map Happisburgh is right next to the sea
