Project summary

Edit project overview to modify the project summary.

The Heiligenbergerbeek is a short stream that runs between Woudenberg and Amersfoort. Its stream valley mainly receives its water from seepage from the Utrechtse Heuvelrug, an ice-pushed ridge. The Heiligenbergerbeek also receives water from the sewage plants in Ede and Veenendaal. When water levels are low, it receives water from the river Rhine to flush the canals of Amersfoort, maintain sufficiently high water levels in the agricultural areas and keep the stream flowing. To ensure the stream keeps flowing, there are several weirs present. When water levels are high, part of the water is discharged by the Vosheuvelbeek and bypasses the city of Amersfoort. To meet WFD criteria, the mowing regime was altered to main channel mowing. Additonally, the stream was made wider in several locations, to allow for wider nature-friendly banks.
