context_page_description: The Hartelkering is a storm surge barrier in Spijkenisse, Netherlands. The barrier is part of the Europoortkering, itself part of the Delta Works project and is designed to close the Hartelkanaal in case of a storm surge.
  The barrier consists of two vertical lift gates, 49.3 metres and 98 metres in length. The gates have a height of 3 metres above NAP when closed. The waterlevel at this location can become higher, but in order to prevent flooding of the Europoort-area the gates were designed to allow the water to overtop the gates in extreme situations. The amount of water would be too small to cause any problems in the protected area but it does limit the surgelevel in the unprotected areas.
  In the raised position the bottom of the gates is at 14 metres above NAP, slightly higher than the bridge next to the barrier. The barrier is equipped with a construction to fend off floating debris, which could damage the gates.
  The Hartelkering was constructed at the same time as the Maeslantkering. The barrier is expected to close once per five to ten years. The decision-making algorithm that sequences storm surge-triggered events in the Maeslantkering is run entirely by computer.

  The barrier consists of two vertical lift gates, 49.3 metres (162 ft) and 98 metres (322 ft) in length. The gates have a height of 3 metres (9.8 ft) above NAP when closed. The waterlevel at this location can become higher, but in order to prevent flooding of the Europoort-area the gates were designed to allow the water to overtop the gates in extreme situations. The amount of water would be too small to cause any problems in the protected area but it does limit the surgelevel in the unprotected areas.
  In the raised position the bottom of the gates is at 14 metres (46 ft) above NAP, slightly higher than the bridge next to the barrier. The barrier is equipped with a construction to fend off floating debris, which could damage the gates.
  The Hartelkering was constructed at the same time as the Maeslantkering. The barrier is expected to close once per five to ten years. The decision-making algorithm that sequences storm surge-triggered events in the Maeslantkering is run entirely by computer.
