Demonstration sites for temporal water retention
The site is situated South of Breda within the catchment of the river Mark. Historically, the river Mark has been strongly embanked. Normalized rivers are straightened and over-dimensioned in width and depth, by which they drain water excessively. During dry periods, low base flows and poor water quality are observed. This has potentially strong implications on water provisioning (water extraction by Waterschap Brabantse Delta). In the Markdal River Basin the structure of the normalized rivers will be restored along a total trajectory of 1 km. By restructuring these rivers (meandering, making drainage basis less deep) water will be stored in the upstream valleys. ln periods of droughts, this water provides the essential base flow to downstream parts of the catchment, improving water quality and quantity.
