Noordwaard polder is flooded under water in The Netherlands | Water mangement

The Noordwaardpolder in the Biesbosch near Werkendam is full of water from the Boven-Merwede. The polder, which collects the water from the river to lower the level at Gorinchem, is completely submerged. The Noordwaard has been a so-called through-flow area since 2015. The dikes are 2 meters above sea level. When the water rises, it automatically flows into the polder. It is arranged in such a way that the roads and houses remain dry. It is some clever watermanagement in the Netherlands to make sure the water doesn't rise too much in rivers and cause floods in unwanted areas (like cities).
