Chesil Cove Curved Seawall
Chesil Cove, Dorset, UK · Original construction 1962-1967; Repairs 2011; Proposed repair/update 2026
The judgement call
Account-gated at launchThe original seawall was constructed in 1965 as a means to protect against ground slippage. - The Shoreline Management Plan mandates a "hold the line" approach for Chesil Cove, requiring maintenance or replacement of existing defences. - Previous repairs in 2011 have been undermined, indicating the persistent challenges of coastal erosion in the area. - The proposed repair and update in 2026 will fall under a new Floods Investment Framework, highlighting evolving funding mechanisms for coastal protection.
Key engineering challenges
Deflecting waves and preventing major slumping of the land above (West Weares). - Sustaining damage from consistent heavy wave attack, coastal erosion, beach loss, foreshore lowering, and structure undermining. - Addressing rotational movement at the southern end of the wall. - Protecting the main A354 road, coastal paths, homes, chalets, and utilities at risk from ground slippage.
