Low river discharges and ongoing soil erosion

Low river discharges and ongoing soil erosionThe long-term drought of 2018 in the Netherlands makes it clear that low river discharges and the ongoing soil erosion on the Waal and IJssel river lead to major depth limitations for navigation. And it is expected that such circumstances will occur more often and longer in the future.

An integrated approach is needed to meet the challenges for flood risk management, water availability, nature and shipping; integral river management. The Plan for Living Rivers of the World Wildlife Fund (WWF) and five other nature conservation organizations is a possible implementation of this integrated approach.

The Dutch television program Nieuwsuur devoted attention to this on 8 November 2018, see (only in Dutch available) https://nos.nl/nieuwsuur/artikel/2258400-bodems-nederlandse-rivieren-slijten-steeds-verder-weg.html.

HKV advised the nature organizations on drafting the vision. Currently, in collaboration with Deltares, we are investigating whether large-scale redevelopment of rivers with flowing secondary channels and longitudinal dams can indeed slow down ongoing soil erosion while at the same time enhancing nature and flood protection.
