Simple download service (Atom) of the dataset: Watercourses subject to the Nièvre Water Act (58)

The classification as a watercourse concerns the application of Articles L.214-1 to L.214-6 of the Environmental Code and is based on the three cumulative criteria of the definition of watercourses in the case-law of the Conseil d’État of 21 October 2011:
— the presence and permanence of a bed, which was originally natural (i.e. distinguishing a stream from a canal or a ditch dug by the hand of man but including in the definition a natural stream originally made artificial, subject to proof);
— a sufficient flow rate for most of the year (appraised on a case-by-case basis by the judge on the basis of local climatic and hydrological data and on the basis of presumptions such as the indication of the “watercourse” on an IGN map or the mention of its name on the cadastre);
— power from a source.

河道（watercourse）的分类适用《环境法典》第L.214-1条至第L.214-6条，并依据2011年10月21日法国最高行政法院（Conseil d’État）判例中对河道的定义所确立的三项累积性判定标准：
— 具备天然原生且持续存在的河床（即区别于人工开凿的运河或沟渠，但若经证明某天然河道曾被人工改造，则仍可纳入定义范畴）；
— 一年中多数时段拥有充足径流量（由法官结合当地气候与水文数据，参照法国国家地理研究院（IGN）地图中标注的“河道”标识或地籍簿（cadastre）中提及的河道名称等推定依据，逐案进行评估）；
— 具备源头水源补给。
