Dataset Direct Download Service (WFS): Non-federal watercourses subject to the Herault Water Act

The classification of watercourses in the case law(1) is essentially based on the following two criteria: — the presence and permanence of a natural bed originally, distinguishing a watercourse from a canal or a ditch dug by the hand of man but including in the definition a natural watercourse originally made artificial, provided that it provides the proof; — the permanence of sufficient debit for most of the year assessed on a case-by-case basis by the court in accordance with local climatic and hydrological data and based on presumptions such as the indication of the “watercourse” on an IGN map or an indication of its name on the cadastre. In order to clarify which parts of the water system are to be considered as watercourses, the interdepartmental instruction of 3 June 2015 requested to establish, at the departmental level, a watercourse mapping and to develop a maintenance guide for river residents. The data entered are derived from the identification of ECs carried out by DDTM 34/SERN/PRNT in collaboration with ONEMA became AFB and the Chamber of Agriculture in 2016. Since then, this mapping has evolved to take into account the findings of the requests for expertise sent to DDTM 34 until 26 November 2018. At this date, a stabilised version is available for download in the Géocatalogue.
