Shoreline management plan and intergrated coastal zone management Flashcards
What is a shoreline management plan?
each sediment cell in england and wales defines distinct management zone for which a shoreline management plan has been written which identifies the natural processes, human activities and management decisions. SMPs are extremely detailed an comprehensive documents and are based on the sediment cell principle that intervention will be largely self-contained within each cell having little or no knock-on effects elsewhere. Each sediemnt cell is treated as a ‘closed cell’
SMPs are recommended for all sections of the coastline in Engalnd and Wales
1) Hold the line - maintaining the current position of the coastline (often using hard-engineeing methods)
2) Advance the line - extending the coastline out to sea (by encouraging the build- up of a wider beach, using beach nourishment methods or groyne construction)
3) managed retreat/strategic realignmnet -
allowing the coastline to retreat in a managedway (e.g. creating salt-marsh environments by deliberately breaching flood bank s that protect lowquality farmland)
4) Do nothing/ no active intervention - letting nature take its course ad allowing the sea to erode clidds and flood low lying land and allowing existing defences to collapse
what is an integrated coastal zone management
The process that brings together all those involved in the development, management and use of the coast . The aim is to establish sustainable levels of economic and social activity; resolve environmental, social and economic challenges and conflicts; and protect the coastal environment
This means complete sections of the coast are now being managed as a whole rather than by individual towns or villages. This is because human actions in one place affect other places further along the coast. Essentially, this is because of the transfers (flows)within the sediment cell, moving sediment from one place another. What is eroded in one location eventually becomes a protective beach elsewhere
