Project summary
Dike realignment took place utilising an area of former brickwork factory. The floodplain was widened by 200 meters and a new secondary channel created. The works also improved habitat connections, by increasing vegetation in the floodplain which will mature over time. The site is now popular for recreation, specifically for water sports, with Arnhem residents.
The channel capacity has increased to allow for significant changes in flow. There has been little effect on biological quality with regard to Water Framework Directive targets, as fish and benthic invertebrates were not monitored before the works were carried out.
