INSPIRE - Atlas of Walloon Karst - Underground flows in Wallonia (BE)

Description

This INSPIRE data layer is based on the tracing of groundwater circulations in the Atlas of Walloon Karst. This INSPIRE compliant data layer comes from the Atlas data of the Walloon karst - Underground flows. In Wallonia, 30% of the subsoil is made up of soluble carbonate rocks (limestone, dolomite, chalk, gypsum, etc.). By infiltrating these rocks, runoff generates a dissolution of these rocks, which gives rise to particular phenomena both underground (caves, underground rivers) and on the surface (chantoirs, sinkholes, collapses, cavities, etc.). These phenomena are called "karstic". By extension, the word "karst" also refers to a limestone region, or more broadly a region of soluble rocks whose landscape is marked by the effects of dissolution. We therefore speak of "rock", "region" or "landscape" karst. The Atlas of Walloon Karst is the reference document for karst phenomena in Wallonia. This data layer is integrated and symbolizes the tracing of groundwater flows in the karst between an infiltration point and an emergence point (loss/resurgence type relationships. This information is one of the major features of karst hydrology. The data layer distinguishes underground flows that have been recognised by tracing (injection of a dye - code 1) from those that are hypothetical (not established with certainty - code 0). On the map, a continuous line represents a traffic recognized by tracing. Hypothetical plots are represented in a discontinuous line (see legend). Each underground flow is uniquely identified. The name of the river is indicated, as well as the loss. A hyperlink allows you to consult the corresponding material safety data sheet. In the Karst Atlas, loss/resurgence links (whether hypothetical or trace-verified) are very generally represented by straight lines between the "incoming and outgoing" of the underground environment. They therefore do not indicate in any way the route taken by the waters to reach the resurgence loss points, which will depend on the nature of the aquifer of the type of terrain, the presence of tectonic accidents and the orientation of the groundwater collector which may, in the karst, be completely independent of the surface relief. In addition, some injection points refer to piezometers and therefore do not correspond to a karst phenomenon. The data layer is continuously updated by the Walloon Commission for the Study and Protection of Underground Sites (CWEPSS) with the help of many collaborators. It is managed by the Geological Service of Wallonia (SPW - DGO3 - DEE - DRIGM)
