(WN) Human management:

• The main reason to prevent cliff erosion is to stop the destruction of homes and buildings but mainly the Walton on the Naze tower which is considered as more valuable as it is a national heritage.
• The rock armour has slowed cliff retreat almost entirely directly behind it, however, erosion has continued at 1-2 meters a year further North and it is inevitable that either the armour will need to be extended or the sea will encircle it.
• The groynes to the south trap sediment from moving North and therefore starved the newly formed beaches of sediment.
• In 2011, 16000 tonnes of rock armour was placed at the foot of the cliff nearest to the Tower to construct Crag Walk.
• The 110 metres of rock armour protects the base of the cliff from hydraulic action and abrasion. It costed £1.2 million.
• In 1999, beach nourishment was added to the beach at the base of the cliffs however the majority of this sand was taken away by longshore drift.
