Bassins versants des stations hydrométriquesCatchment areas of hydrometric stations
This geospatial dataset delineates the topographic catchment areas (watersheds) associated with hydrological measurement stations in the Canton of Geneva, Switzerland. It is published as part of the Geneva territorial information system (SITG) and maintained by the Department of the Territory (DT), Water Ecology Service (SECOE), Water Dynamics Unit. The data supports hydrological analysis and water resource management by linking monitoring stations to the drainage areas that feed them, useful for environmental and water-related studies at the cantonal level.Cette couche de données représente les bassins versants topographiques des stations de mesures hydrologiques du Canton de Genève. L'organisme responsable de cette donnée est le Département du territoire (DT), Service de l'Ecologie de l'Eau (SECOE), Entité Dynamique de l'Eau.
