MANAGEMENT AREA STATEMENT

MANAGEMENT AREA 4
"SEA" - WALCOTT TO WINTERTON NESS

Processes

Greatest exposure to waves is onshore-offshore but a strong longshore wave energy exists, producing a net southerly drift of material but highly variable directional between storms. Erosion is particularly apparent over the central sections of this area, with the exposure of underlying clays and beach downcutting. Retreat of the natural beach and loss of dunes in front of low lying flood plains is a major feature in the Area.

Key Strategic Issues

This area sees a change in the coastal area from low lying cliffs in the north to low lying flood plain to the south, with the coastline in retreat throughout. The northern end is mainly agricultural land, with the exception of the village of Happisburgh. Continued erosion will result in the loss of some assets and ultimately could pose a threat to the flood plain further south. To the south any further retreat of the coastline would result in widespread flooding of the Broads. The present seawall has prevented any natural rolling back of the natural dune system over much of this stretch. The strategy here must be to continue to prevent the occurrence of flooding in this area.

Management Units

This Management Area has been sub-divided into three Management Units as follows:

SEA 1 - Walcott, Ostend Cottages to Happisburgh, Caravan Park
SEA 2 - Happisburgh, Caravan Park to Eccles, Cart Gap
SEA 3 - Eccles, Cart Gap to Winterton Ness

Developed Strategy

The resultant defence strategy developed for this Management Area is as follows:

SEA 1: MANAGED RETREAT OF THE EXISTING LINE
SEA 2: HOLD THE EXISTING LINE
SEA 3: HOLD THE EXISTING LINE
