The qualification of a watercourse is based on three cumulative criteria which must therefore be used to characterise a watercourse: 1 the presence and permanence of a bed, which was originally natural; 2 a sufficient flow rate for most of the year; 3 power from a source. The instruction of 3 June 2015 recalls that the methodology for identifying watercourses is based on the case law of 21 October 2011 of the Conseil d’État. Namely: “is a watercourse, a flow of running water into a natural bed originally fed by a source and having a sufficient flow of much of the year”. The list of rivers already determined by other regulations has been included in this identification, since they have previously been classified as having an interest in ecological continuity, as biological reservoirs, etc. The automatically integrated streams are as follows: — Lists 1 and 2 of L214-17 for ecological continuity — The biological reservoirs of the SDAGE — Bodies of watercourses — Rivers to be preserved primarily by the SAGE Ill Nappe Rhin — Full features named — Natura 2000 rivers As a result, river mapping will be updated according to its evolution in September of each year. It will represent new hydrographic areas validated with rivers and expert ditches. In addition, information will be provided on which flow it will be mandatory to set up a grassed strip (GAEC: Good agricultural and environmental conditions) of 5 metres.河道的认定需基于三项累计标准，且必须通过这三项标准对河道进行特征刻画： 1. 天然形成的河床的存在及其持续性； 2. 一年中多数时段具备充足径流量； 3. 拥有稳定的水源补给。 2015年6月3日发布的指令重申，河道识别方法需依据法国国务委员会（Conseil d’État）2011年10月21日的判例规则，具体定义如下：“河道指由水源补给、拥有天然河床且一年中多数时段具备充足径流量的流动水体”。 此前由其他法规划定的河道名录已纳入本次识别范围，因上述河道此前已被归类为具有生态连续性价值、可作为生物蓄库的水体等。 自动纳入识别范围的溪流包括： — 用于生态连续性评估的L214-17条款第1、2类清单 — 流域水环境综合治理规划（Schéma Directeur d'Aménagement et de Gestion des Eaux，SDAGE）划定的生物蓄库 — 河道水体 — 莱茵河地下水层流域管理规划（Schéma d'Aménagement et de Gestion des Eaux，SAGE）划定的需优先保护的河道 — 已明确标注完整属性的水系 — 纳入自然2000（Natura 2000）保护体系的河道 据此，河道测绘图将于每年9月根据河道的动态变化进行更新，新版测绘图将涵盖经审核验证的新增水文区域及专业认定的沟渠。此外，还将明确需强制设置5米宽草带的径流区段，该草带需符合农业与环境良好作业规范（Good Agricultural and Environmental Conditions，GAEC）。
