Dataset Direct Download Service (WFS): Watercourses law on water in the Rhône department

Watercourses determined as subject to the Water Act under the Non-Domanial Watercourse Policy provided for in Article L215-4 of the Environmental Code
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distinguishing a stream from a canal or a ditch dug by the hand of man but including in the definition a natural stream originally made artificial, provided that it proves this;
— the permanence of a sufficient flow for most of the year assessed 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.

依据《环境法典》第L215-4条规定的非国有水道政策，被认定受《水法》管辖的水道。
判例法(1)中对水道的分类主要基于以下两项标准：
—— 原生天然河床的存在与持续性：以此区分溪流与人工开凿的运河或沟渠，但若能举证证明，则将原本天然、后经人工改造的溪流纳入定义范畴；
—— 全年多数时段拥有充足径流的持续性：由法官结合当地气候与水文数据，结合推定规则（如IGN地图中标注的"水道"字样，或地籍簿中记载的水道名称）逐案进行评估。
