Project summary

Edit project overview to modify the project summary.

Water authority Vechtstromen took several measures to improve the ecological quality of this stream and improve its function as a link between the Boerskotten natural area and the river Dinkel. After a succesful experiment with sand suppletion in the upper part of the stream, they implemented the same measure further downstream. This makes this section more shallow. Locally, they created a less straight trajectory. Gravel suppletion was added to the sand suppletion in some locations.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

The original stream valley vegetation types have started to recover after the measure was implemented. The water retention capacity of the stream has improved as well.
