Project summary

Edit project overview to modify the project summary.

The Channel of Deurne and the parallel Helenavaart transport water from the river Meuse. The channels were originally dug out to facilitate peat transport and now mainly serve to maintain a sufficiently high water level in the surrounding area. Floating debris caused flooding problems in downstream areas. Rather than mowing all the vegetation, the water authority decided to only mow a 4 meter wide strip of the main channel.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

The number of species causing an increase in upstream water level has declined.
