ENGLISH

The goal of the Dutch Room for the River Programme is to give the river more room to be able to manage higher water levels. At more than 30 locations, measures will be taken that give the river space to flood safely. Moreover, the measures will be designed in such a way that they improve the quality of the immediate surroundings. The Room for the River programme will be completed by approximately 2016.

MEASURES: HOW WE WILL MAKE ROOM FOR THE RIVER

Every river is different and requires an individual solution in order to make room for the water. This page provides an overview which measures and techniques we use to make room for the river.

Uiterwaardgraving

Lowering the flood plain

Lowering the flood plain

Lowering sections of the flood plain gives the river more space during periods of high water. Over the past few centuries, the natural process of sedimentation has gradually raised the level of the flood plain. Excavating the top layers of the flood plains makes them lower, which in turn contributes to making room for the river.

Zomerbedverlaging

Deepening the summer bed

Deepening the summer bed

The bed of the IJssel river will be dredged to make it deeper over a length of 7.5 kilometres between the Stadsbrug in Kampen and the Eilandbrug near the Ketelmeer. This will create more room for the river.

Waterberging

Water retention

Under exceptional circumstances, such as when the storm surge barrier is closed and the river is discharging large volumes of water to the sea, the Volkerak-Zoommeer lake will serve as a temporary water storage area to retain the excess river water.

Dijkverlegging

Dyke relocation

Dijkverlegging
Dyke relocation

Relocating a dyke land-inwards increases the width of the flood plains and provides more room for the river. This entails exposing land that had once been protected by the dyke to high water in order to expand the river’s winter bed. 

Kribverlaging

Lowering perpendicular groynes and building attracting groynes

Lowering perpendicular groynes and building attracting groynes

By lowering the groynes in the river and building parallel barriers, the river will be able to drain excess water easier. A perpendicular groyne is constructed at a right angle to the flow of the river. These groynes will be lowered or removed. Attracting groynes are constructed parallel to the flow of the river.

Hoogwatergeul

High water channel

High water channel

A high water channel is a branch of a river used to drain high water via a different route. The channel is not excavated below the water table, but rather formed by building two dykes in the landscape.

Ontpoldering

The dyke on the river side is moved land-inwards, so that the river can flow into the area during periods of high water.

 

Obstakelverwijdering

Removing obstacles

Obstakelverwijdering
Removing obstacles

Removing or modifying obstacles in the river wherever possible helps increase the flow rate for the the river water. Removing obstacles includes work such as lowering or eliminating ferry pier banks, widening bridge openings and removing or lowering quays and flood-free areas.

Dijkverbetering

Strengthening dykes

In several areas where widening of the river is not an option due to lack of space, the dykes may be strengthened instead.


Room for the River in three minutes

Room for the River Corporate Clip

Room for the River, Corporate Clip. The river will be given more room at more then 30 locations covered by the 'Room for the River' programme. The main objectives of this programme are to complete the flood protection measures by 2015 and to improve the overall environmental quality in the river region.
