The sand spit that makes up Dawlish Warren is of strategic importance for the flood risk management of low lying areas along the River Exe estuary, particularly communities at Starcross, Lympstone and Exmouth, as well as the main Penzance-London railway line.
As part of the Exe Estuary Flood and Coastal Erosion Risk Management Strategy, a beach management scheme is being undertaken in 2017 by BMMJV for the Environment Agency and Teignbridge District Council.
The scheme is designed to reduce the risk of erosion to the narrow section of the spit (the 'Neck') and includes dredging works to replenish the beach, the repair and replacement of timber groynes and the installation of a geotube hard defence within the dune system.
Richard Cox, the Environment Agency Project Manager for the scheme, will introduce the presentation. Dr Paul Canning of Atkins will discuss the flood risk and design considerations of the scheme, while Lawrence Jones, a Chartered Civil Engineer and Sub Agent with BAM Nuttall Ltd, will explain the nature of the beach management scheme currently under construction. The talk will include the significant public interaction involved and the environmental considerations associated with working in a SSSI and SAC nature reserve.
