2m a year

Why is a fast rate of erosion such a problem for the people of Holderness?
costs a lot to protect the coastline by building structures like groynes and sea walls; erodes lands that farmers use which can limit their production; gasline that is in place provides a lot of jobs for local people would be very expensive to move.

What causes the Holderness coast to erode so easily that is to do with the sea?
located next to the North sea which has powerful destructive waves (especially in winter). The sea level is also really deep which means huge waves aren't slowed down by friction when they reach the coast.

What hard engineering strategey were used at Hornsea along the Holderness coast and what effects did it cause further along the coast
wooden groynes were put in place which protected Hornsea however Mappleton was loosing sediment which resulted in the coast eroding by 4m a year in the 90's
