Project summary

Edit project overview to modify the project summary.


The Beekloop is a mostly man-made stream that originates in the woods between Aalst and Hezen and discharges into the Kleine Dommel near the Hulsterbroek natural area. The stream is located on the edge of the higher Kempens Plateau (Belgium) and a lower area in Noord-Brabant (Netherlands), which results in a relatively large bed slope. The Beekloop was part of several stream restoration projects between 2010 and 2015, some which can be classified as traditional stream restoration and some of which focused on Building with Nature.

One of the main Building with Nature measures that were carried out is the introduction of dead wood in the stream. In addition, specific flora were introduced to improve the flow conditions.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.


In additon to the usual measurement of hydrological, biological, and physical-chemical quality elements, chemical measurements were also taken. The stream was strongly polluted prior to the measures. Therefore, concentrations of heavy metals, micropollutants and pesticides were monitored.
