Remediating a Coastal Landslide?

[robmclellan]

What is the best to remediate a coastal landslide? The area that i am looking at is Lyme Regis, UK, where the towns stability is failure. Also the famous Black Ven Landslide Complex is nearby. Would it be to place an embankment 50m offshore to decrease the energy of the waves?

Thanx

Hi Rob

A PhD student at the University of Portsmouth was studying the landslides of the Dorset/Hampshire coast and may well be able to point you in the right direction.

His name is Andy Gibson. Possibly Dr Andy Gibson by now!

The university number is 02392 876543 - ask for Andy Gibson in the geology department. If he is not there then either Mike Chaplin or Andy Poulsom might know his contact details.

My tuppence would be to say that lowering the energy of the waves would certainly reduce the erosion of the toe of the feature but would not account for loading at the top end nor the effects of hydrostatic pore pressure (which can 'lubricate' the failure plane and allow movement).

Another (ex-Portsmouth university) expert in this field is Dr Bill murphy, although his interest in landslide activation is more earthquake-oriented.

You might like to contact MTRCA in Toronto Ontario. This might be similar to the Scarborough Bluffs situation. Also you might try a search in geotechnical journals of an author named MAJ Matich. He wrote a couple of papers I believe on remediation at the bluffs.
