The coastline of Holderness

Image H11 : Sea defence at Mappleton 
(Ref: TA  229 439)

The sea defence at Mappleton was designed to cut down the erosion.  Large boulders (called 'rock armour') were placed along the foot of the cliff, and built out into the sea to form a groyne.  The plan was to create an obstruction which would lead to the deposition of a beach - which would absorb the power of the waves and protect the cliff.  To the left of this photograph we see the success of the groyne in developing the beach.
