Project Description Summary

This project involved the installation of one pipe in seawall: 45cm diameter. Water exchange volume approx. 3,000m3. Water retained at low tide using a concrete drop board sluice (to keep water levels of 50cm at low tide). Concrete weir set back approx. 20 feet from the seawall allows further water control if considered necessary. As part of this scheme a built perimeter bund was included (none of the bunding works are connected to the sea wall). Concrete weir is in the RSPB's bund wall into the lagoon. Constructed 6 islands, made traversing ancient chalk road into 7th island.
