Habitat Creation
This project involved the installation of four twin pipe structures (2: 0.6 and 0.45m; 1: 0.53 and 0.3m; 1: 0.3 and 0.22m diameter).
Invert levels approximately at MHWS.
Pipe has slope towards the river to encourage drainage of fields to mimic saltmarsh drainage.
Site only floods on springs (neap tides dont get as far up the estuary).
Average spring water exchange volume: 8,800 m³.
Part of this scheme involved the excavation and reinstatement of relic saltmarsh creeks to move water around the fields (remnant creeks in larger field, new channels in smaller fields).
Fencing and cattle access improvements (opened up old cattle creeps under the old railway line, which is now the Camel Trail).
Grazed site extensively before flooding (to get grass levels low, so if there was a lot of grass die off it would not be so dramatic).
