The floodplains are flooded by rain and meltwater from the Alps. Trees and bushes are under water. The floodgates of weirs and sluice gates are up because of the high water.
Hydraulic engineering structure in the Lower Rhine.
The two visor panels (arched steel constructions) of the Amerongen weir and lock complex are up due to the high water.
The weir at Amerongen (and Maurik) must maintain the water level between Driel and Amerongen. When there is little water supply via the Rhine, closing the weir ensures that the water in the hinterland does not drop too low. In this way sufficient fresh water remains available for agriculture and the waterway remains deep enough for shipping. If there is too much water, the weir will be removed from the river so that the water can flow quickly towards the North Sea.
Each weir here is fitted with a so-called visor valve: a semicircular valve weighing approximately 200 tonnes. This gate is lifted by means of cables. The way the valve moves reminds one of the visor of an old knight's helmet.
