Marche-en-Famenne: Hydrological and hydraulic study for Hedrée to avoid future floods

Since then, the city has already acted by planning a temporary immersion zone between the villages of Harsin (Nassogne) and Hargimont (Marche), adjacent to the place called Marengo.

The city of Marche has also just responded to a call for projects from the Walloon region, again with the aim of creating a temporary diving area, but this time on the Hedrée level, a second-category course that flows into the Wamme. “We want to fight the floods and do everything in our power so that a disaster like the one experienced in July 2021 can be avoided in the future.” points out First Elder Nicolas Gregoire. The proposed solutions aim to act on the peaks of flow arriving at Wamme. The Commune will therefore entrust Idélux Eau with an exploratory mission to establish the hydraulic functioning of the Hedrée as well as the hydrological functioning of the contributing catchment.”

This study should also propose technical solutions aimed at regulating the flow and thus reducing the occurrence of floods.

Unanimity, of course, among Marchois’ advisers.

However, Jean-Pierre Georgen (MR-min) suggested that the majority combine this study with the Wamme study, as the two rivers are clearly closely connected. Senior Nicolas Grégoire replied that this would probably be done through the design bureau appointed by the Walloon region.
