Annexes hydrauliques et zones de frayères des voies navigables morbihannaisesHydraulic annexes and spawning grounds of Morbihan navigable waterways
This API provides data on hydraulic annexes and spawning grounds along the navigable waterways of Morbihan, France. These waterways are classified as heavily modified water bodies under the EU Water Framework Directive (WFD). Achieving good ecological potential, as defined by the WFD, requires actions such as restoring functional riparian aquatic habitats. The dataset supports environmental monitoring and water management efforts in the Morbihan department, and is published via the Brittany regional open-data portal (data.bretagne.bzh).Les voies navigables morbihannaises sont classées en masse d'eau fortement modifiée par la Directive Cadre sur l'Eau (DCE). L'atteinte du bon potentiel écologique, tel que défini par la DCE doit mener à conduire des actions qui visent à : - restaurer des habitats aquatiques riverains fonctionnels...
