This dataset corresponds to the atlas of the hydrographic network of the Brussels-Capital Region, in accordance with the Decree of 23 May 2024 classifying non-navigable watercourses, designating regional ponds, determining the content, scope, procedures and deadlines for drawing up the Atlas of the hydrographic network of the Brussels-Capital Region and adopting this Atlas. It is made of ten geometric classes: classified watercourses, unclassified watercourses, bank crests, regional ponds, ditches, engineering structures, sluice walls, watercourse points of origin, cross profiles, embankments.

Brussels-Capital Region : This flood hazard map identifies areas where flooding could occur due to stream overflow, runoff from rainwater, overflowing sewers or a temporary rise in the water table, even in places where no flooding has been observed until now. The absence of a flood hazard zone on the map does not guarantee that flooding will never occur as it does not take into account certain causes of flooding such as a local failure of the sewage network, etc. Please note that these maps have no regulatory value, they have been produced in accordance with the European Directive 2007/60/EC to determine the prevention and protection measures. The maximum scale is 1/10.000 as the modelled data are not representative on a larger scale.

Brussels-Capital Region :

This dataset corresponds to hydrography in the Brussels-Capital Region. It is made up of nine geometric classes: drainage basins, arched watercourses, open watercourses, surface water (ponds, marshes, swamps), surface water bodies, springs, right-of-way zone for arched watercourses, non aedificandi zone.

Brussels-Capital Region : location of the different surface water quality monitoring sites under the Water Framework Ordonnance and Directive. Surface waters concerned are surface water bodies: Canal, Senne and Woluwe. Monitoring involves a series of chemical, physico-chemical parameters... The code and the name of the monitoring site are given.
