Dommel

We consider here the total catchment area of the Dommel River with a surface area of over 2850 km2 and a maximum height difference in the order of 80 m. About 85% of the catchment area lies in the Netherlands and 15% in Flanders. The main (partly) cross-border tributaries in the Dommel catchment are the Tongelreep, Poppelsche Leij, the Rovertsche Leij and the Groote Aa.

The Dommel rises on the Kempisch Plateau at Peer and flows northwards. The watercourse was straightened and regraded over a large length. Via Overpelt and Neerpelt, the Dommel flows into the Netherlands where it drains into the Meuse via Eindhoven and Boxtel at 's Hertogenbosch. Discharges and water levels are measured at Overpelt, Peer and 'Station P01 Dommel'.

The Tongelreep also originates on the Kempish plateau in Belgium as Warmbeek. At three points, the Tongelreep is fed by Maas water brought in via the Bocholt-Herentalskanaal. The Tongelreep drains into the Dommel near Eindhoven.The Tongelreep has retained its original course over much of its length. Discharge and water level data are collected at Ackel and 'Station P03'.

Upcoming research: 

For the Dommel river basin, a joint transnational stresstest will be probably developed and tested from 2025 onwards. With a stresstest, we try to investigate the resilience of the water systems for extreme weather conditions and identify which measures may be considered to become better prepared for these extreme floods and droughts. Read more details about the development of a transnational stresstest approach for Flanders-Netherlands in our magazine.

What-if simulation in Flanders with precipitation July 2021 (Dutch)

This report describes what the impact would be if a water bomb such as the one that occurred in July 2021, and caused a lot of damage due to floods in Wallonia, would fall across the whole of Flanders. Two precipitation events are calculated for which hydrological and hydrodynamic calculations were carried out with the model instruments of the Hydraulic Engineering Laboratory. Flood maps were then calculated along the navigable waterways and damage calculations were made (report only in Dutch).

Resilient Waterland - Weerbaar Waterland (Dutch)

Advice of the expert panel on flood protection to the Flemish government. With 'Weerbaar Waterland', the expert panel formulates an adapted strategy for water security in Flanders, with ten coherent actions and a plan of action to implement it as soon as possible.

Advice on droughts Brabant: Zonder water, geen later (Dutch)

Advice to Brabant's (ground)water partners on the structural adjustments that are needed in the (ground)water system, (ground)water management and (ground)water use from an integral and long-term perspective on drought, and what this requires from all parties that have (direct) influence on this.
