CREATING MARSHLAND FROM MUDFLATS
- can be encouraged by planting vegetation
e.g. glassworts.
- vegetation stabilises sediment & stems & leaves, reducing wave speed.
- therefore, waves' erosive power & how far they reach inland are reduced, leading to less flooding of the area around the marsh.
COASTAL REALIGNMENT (MANAGED RETREAT)
- breaching existing defence, allowning the sea to flood the land behind.
- e.g. breaching sea walls @ Holderness.
- over time, vegetation will colonise the land & it will become marhsland.
