Preparing For Floods In The Netherlands
08 May 2009 | 1 min read
The Water Board has therefore commissioned RPS to redesign the Bergboezem polder as a massive water storage area which can prevent drainage systems becoming over-loaded – and thereby minimise the risk of flash-flooding in the surrounding region.
The Bergboezem polder lies well below sea level. It is surrounded by small dikes and is kept dry by windmills and pumping stations. Unlike the surrounding polders, the Bergboezem polder is used solely for agriculture – and therefore is most suited to deliberate flooding during times of extreme rainfall.
The primary objective is to reshape the polder in such a way that a water holdback capacity of 1.2 million cubic metres is formed. The secondary objective is to turn the reshaped polder into a nature reserve. These objectives are combined in one integral development plan. RPS is currently working on the design of the new polder – including all the engineering aspects. Subsequently RPS will prepare the contract documents and represent the Water Board during the construction phase.
