Hartel barrier
The Hartelsperrwerk ( Dutch Hart Elkeringhausen ) in Hartelcanal in Spijkenisse is the same as the Maeslant barrage part of flood protection for the port of Rotterdam and is part of the Delta Plan . Both barriers were built between 1991 and 1997. The barrage in the canal is controlled by the BOS computer system (German decision and support system), which means that both barriers are closed at the same time.
The Hartel barrier consists of two elliptical lifting gates with a width of 49.3 m and 98.0 m, which are suspended vertically movable between three towers. The towers stand on the pillars of the Hartel Bridge. When closed, the water level is three meters above NAP . If water flows over the gates, it is not dangerous for the hinterland, but higher weirs would flood the Europoort and the dikes on the Brielse Maas . Due to the overflushing that may be tolerated, the Hartel barrage is the only one among the Dutch storm surge barriers that has something in common with a weir . The Hartel barrier is checked once a year together with the Maeslan barrier.
On the night of November 9, 2007, the barrage was closed for the first time due to the threat of a storm surge when the Tilo storm hit Central and Northern Europe. The water level at the Hartel barrier rose to a maximum of 2.84 m above the Amsterdam level. At the same time the Maeslant barrage was closed. On January 3, 2018, the Hartel barrier was closed again during the Burglind storm , the maximum water level was 2.60 m above Amsterdam level.
