NEW METHOD TO CLOSE TIDAL RIVERS

Hans-Gerard Kniess

Abstract


The closing of tidal rivers is still a risky project as the tidal flow alternates periodically its direction, velocity and level. On the last essential section of the Eider dam project a new method for closing tidal rivers was invented and successful operated. Contrary to common methods the main channel of the river was closed only by hydraulic placement of sand under protection of two permeable pile walls with perforated steel panels.
