Breach - no control

Breaches can be made in a sea wall to allow the sea to enter whilst retaining the majority of the wall. This provides greater protection in the early stages of realignment as the intact part of the seawall acts as a wave break and facilitating the development of a saltmarsh sward. This technique is more frequently used as for example at:

Guidance: From the examples in the south east of England, the size and spacing of the breaches are important. A width of 50m seems to be favoured with the positioning set to correspond to the former location of tidal channels on areas where the realignment site is on enclosed, former saltmarsh.
