Walloon river system
The Walloon Hydrographic Network (Réseau Hydrographique Wallon) centralises information on rivers in Wallonia, Belgium, together with associated uncertainty zones around their mapped courses. It is a vector geospatial dataset referenced in the 2008 Belgian Lambert projection and covers the entire Walloon territory. The dataset combines known administrative classifications with up-to-date planimetric geometry, allowing rivers to be located and identified precisely. It is maintained by the Service public de Wallonie and made freely available without authentication, serving as a reference layer for water management, hydrography, and spatial planning applications across the Walloon region.},The Walloon Hydrographic Network (WHN) centralises information on Walloon rivers and associated uncertainty zones.
