The risk of flooding to coastal settlements around the UK is high and increasing due to sea-level rise and an increase in extreme rainfall events from the effects of climate change. The Environment Agency has carried out extensive modelling to determine the likely extent and range of the potential flood events over the next 100 years.
The current flood defences in the Adur estuary do not provide a high enough level of protection, and in places are in poor condition. This leaves Shoreham-by-Sea, Lancing and the surrounding areas at risk of flooding. The Environment Agency has been developing a major improvements scheme called the Shoreham Adur Tidal Walls. The scheme will provide protection for extreme events with 0.33% probability (1-in-300-year) of occurring in 1 year, allowing for 50 years of sea-level rise.
The scheme is separated into 10 reaches, or lengths, of the estuarine bank. The design of the defences varies between the reaches.
The Environment Agency held consultation events in 2014 and 2015 to gain feedback on the designs and they have incorporated feedback into the detailed designs.
Images from the scheme can be found in the Environment Agency Shoreham Adur tidal walls Flickr album.

The Environment Agency is working in partnership with West Sussex County Council and Adur District Council to design and build the new defences. The Coast to Capital Local Enterprise Partnership has also contributed funding to the scheme.
