Hautes et basses eaux des nappes souterrainesHigh and low groundwater levels

APIExecutable4/7Query nowOpen workbench Subscribe🇫🇷France

This API provides access to a dataset of point features representing measured depths for high and low water levels of underground aquifers across the territory of Bordeaux Métropole, France. The dataset aggregates information from various sources cataloguing the monitoring structures (wells or boreholes) used to record these groundwater level measurements. It is published as open data by Bordeaux Métropole and can be used for hydrogeological studies, water resource management, and monitoring of groundwater fluctuations within the metropolitan area.Dictionnaire Public Ce jeu de données représente, sous la forme d'objets ponctuels, les profondeurs mesurées pour les hautes et basses eaux des nappes souterraines sur le territoire de Bordeaux Métropole.
