Project summary

Edit project overview to modify the project summary.

The Deurningerbeek is a tribuatary of the Oude Bornsche Beek, which is in turn a tribuatary of the Linderbeek. This stream is already a site for traditional stream restoration. The bed was realigned to a meandering trajectory. In addition, the water authority wants to experiment with a thirty year suspension of maintenance.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

Water quality indicators are monitored for compliance with Water Framework Directive goals. In addition, the hydrological and ecological effects are monitored as part of the 'Building with Nature in streams' project. So far, suspended maintenance has led to the establishment of an alder carr (Dutch: Elzenbroekbos). It is likely that the dry summers of 2018 and 2019 have caused some ecological damage due to the stream running dry.
