Cliff stabilization

Cliff stabilization is a coastal management erosion control technique. This is most suitable for softer or less stable cliffs. Generally speaking, the cliffs are stabilised through dewatering (drainage of excess rainwater to reduce water-logging) or anchoring ==External links==The basic cause of cliff instability is normally the marine erosion of the foot of the cliff, mitigation of this is covered under the protection method.

Artificial smoothing of the slope, if there is enough space at the foot as well as at top of the cliff for this. This will help the future with weathering and sliding. Smoothing of the slope by filling with material at the foot of the cliff. If we cover on the cliff with plants it could help to smoothen of the slope. Good vegetation protects against weathering and groundwater seepage, and could prevent sliding. Drainage of groundwater. This can be used if the cliff suffers from sliding due to high groundwater pressure and poor drainage conditions. Horizontal and vertical drains can be used as well as the regulation of the surface runoff.

Cliff slopes are often protected by dumping assorted rubbish, such as branches etc., over the cliff. It is a bad “solution” because it does not stop the risk of sliding.
