During the yearly Coastal Ecology meeting, we visited the managed realignment project (ontpoldering) near Lippenbroek, Belgium. The Belgians allow Scheldewater to enter a former polder area so that a reduced tidal regime is established. Due to the tidal water, a very interesting and diverse (for floodplain standards) intertidal community has established.
