Soft engineering approaches (beach nourishment, cliff regrading and drainage, dune stabilisation) attempt to work with physical systems and processes to protect coasts and manage changes in sea level.

2024年10月3日 · Reducing the angle of the cliff to stabilise the slope. Drainage of water also stabilises the cliff against mass movement. Planting species like Marram grass so that the roots bind the dunes. The dunes absorb wave energy and protect the land behind them. This is a form of do-nothing or managed retreat.

Artificially reducing the cliff angle with bulldozers at the cliff behind the beach to reduce cliff height and slope angle, reducing mass movements. Geography Coastal environments

-regrading - Reducing the angle of a cliff to stabilise it-drainage - removes excess water to prevent landslides and slumping

Soft engineering techniques involve working with nature to manage the coastline. Techniques include cliff stabilisation, dune regeneration and managed retreat. Beach nourishment involves adding sand and shingle to a beach from elsewhere.

- Cliff Regrading and Drainage: Inserting pipes within a cliff to remove excess water. Cliff is still open to wave erosion but technique prevents mass movement and clay build-up. - Beach/Dune Stabilisation: Widen the beach/dunes to dissipate wave energy. Sustainable management aims to meet the needs of today without destroying the needs of the ...

Cliff Regrading - Soft Engineering -Restructuring the cliff face by extending it, making the slope longer and less steep to reduce mass movement/make the beach safer. Pros: Cliff more stable, less prone to unexpected movement and gives locals confidence they won't lose their home.

what is cliff regrading and drainage? Cliff regrading reduces the angle of the cliff to help stabilise it. Drainage removes water to prevent landslides and slumping. what is sustainable management? what is ICZM? what are SMPs? what is meant by the term 'hold the line'? maintaining or upgrading the level of protection provided by defences.

Cliff profiles are influenced by geology, especially the resistance (to erosion) of the rock, and the dip of rock strata in relation to the coastline. Joints are fractures in rocks created without displacement. They occur in most rocks, often in regular patterns, dividing rock strata up into blocks with a regular shape.

Cliff regrading and drainage is especially useful when the cliff is made of clay or other material because this material erodes easily and can slip when wet. Drainage does not cost much money and can get great results because it reduces the amount of the water in …
