Groynes increase erosion down the coast, e.g. Cowden Farm south of Mappleton at risk
6 of 8
Give three ways less material moving down the coast effects erosion
Less to slow flood water increases risk of flooding in Humber Estuary / Less increases rate of coastal retreat down Lincolnshire Coast / Spurn Head at risk of being eroded away as less new material added

Why do the defences get more expensive to maintain once put in place?
Protected areas form headlands which are more heavily eroded so more expensive to maintain defences
