Tidal & Coastal Case Studies

Cain Bio-Engineering have undertaken numerous tidal protection, enhancement, erosion control and management projects over the last 30 years. In our tidal case studies section you will find more information, photos, videos and documentation about some of our favourite projects.

Tidal Case Study: Abbotsbury Swannery

by Jake Dew on October 12, 2012

Project type:  Erosion Control
Location:  Abbotsbury Swannery, Dorset
Length: 320m
River: Chesil Fleet
Client:  Strangways Enterprises
Installation date:  2012

Project Brief

The ancient dry stone wall which had once acted as a breakwater to protect the Swannery had fallen into disrepair. This resulted in frequent tidal inundation and loss of land behind the dilapidated wall. Consequently the bank margins of the decoy pond became heavily eroded which was exacerbated by the wildfowl population. High levels of siltation were recorded within in the decoy pond, and nationally important reed bed habitat was lost.
