Regulated tidal exchange
Mainland coast of East Friesland (Niedersachsen)
Demonstration or Pilot Project
This involved the installation of one sluice: 1.3m diameter, invert at 0NN (-1.8mMHW); average water exchange volume: 7,000m3 (12.000m3 at spring tides)); creek water levels maintained at .3 NN; max. flow velocities: 0.77m/s. As part of this scheme the existing creeks were deepened; thresholds/pipes were installed in several creeks to help raise overall water levels.
