Groundwater tracing in Burgundy-Franche-Comté: traffic identified

The geographical database includes all groundwater tracings carried out in Burgundy-Franche-Comté since 1829, with the aim of identifying groundwater circulations in the karst zone. It lists more than 2,600 tracing operations carried out by various organisations (research offices, university laboratories, etc.). This data may be used to: - look for a trace on a commune, - visualise groundwater circulations over a geographical area. The data visualised is divided into 8 layers, each of which is detailed in the “learn more” concerning it. About the layer of identified circulations (“tracages_trait_inj_rest”): each line connects an injection point to a monitoring point where restitution is observed. This visualises effective circulation. It indicates that underground traffic exists between the two points but without giving information on the route taken by the water. The column ‘output yes/no’ shall be filled in: Yes.
