ABPmer supports detailed engineering design of Southsea Coastal Defences

Find out about our involvement in latest phase of the Southsea Coastal Scheme, reducing flood risk for over 8,000 homes and 700 businesses.

The Southsea Coastal Scheme stretches for 4.5km from Old Portsmouth to Eastney and will reduce flood risk to over 8,000 homes and 700 businesses. Designed not only to protect people and property, its design will improve the seafront for future generations.

ABPmer was part of a specialist team that designed the Principal Scheme in 2018, providing wave transformation modelling, overtopping analysis, weather downtime, coastal process studies and supporting sediment transport modelling. We also provided beach design criteria through a Beach Philosophy Document using width as the prime metric of beach condition, and the trigger for intervention if and when required.

We have been retained to support the detailed engineering design, providing updated extreme wave and water level data based on the latest scientific data, along with coastal and metocean scientific advice when required.

Heidi Roberts, Design Support Business Manager, said:

“We are very pleased continue supporting East Solent Coastal Partnership, Portsmouth City Council and its consultant engineers Royal HaskoningDHV and Atkins on such an important project.
Understanding beach change and extreme flood events under a changing climate is key to the long-term sustainability of the project, and we are excited to continue providing support in this area.”

ABPmer regularly undertakes numerical modelling of waves, tides and sediments along with studies on beach and estuary geomorphological change.
