This dataset from the Système d'information du territoire genevois (Geneva territorial information system) inventories regulation structures located in watercourses in the canton of Geneva. In addition to general civil engineering information, each record includes an assessment of the structure's ecological impact on the environment. Entries are generally illustrated with a photograph of the structure. The dataset supports water management, environmental monitoring, and infrastructure planning within the Geneva canton.Cette couche recense les ouvrages de régulation situés dans les cours d'eau. Aux informations générales de génie civil s'ajoute une évaluation de l'impact écologique de l'ouvrage sur l'environnement. En général une photo illustre l'ouvrage.
