Bodies of watercourses – Métropole – Version Reportage 2010

A river water body is a distinct and significant part of surface waters such as a river, river or canal, a portion of a river, river or canal, constituting the elementary division of aquatic environments intended to be the assessment unit of the WFD. River water bodies are derived from the BDCarthage® v3 hydrographic theme of the BDCarto®. The criteria for the realisation of river water bodies are: — A body of water belongs to a single hydroecoregion — The dominant fish population based on the fish context (Salmoniculture, Cypriniculture, Intermediate) — Size class (strhler confluence row) The water body code is structured as follows: Water body type code + Basin code (district as defined in dce) + Increment DCE reporting correspondence: this entity corresponds to the concept of River Water Body (RWBODY) of WISE.河流水体（River Water Body）是河流、河道或运河等地表水体中独立且重要的组成部分，为河流、河道或运河的一段，是水生环境的基本划分单元，旨在作为欧盟水框架指令（Water Framework Directive, WFD）的评估单元。 河流水体源自BDCarto®平台的BDCarthage® v3水文主题数据集。 河流水体的划定标准如下： — 该水体隶属于单一水生生态区 — 基于鱼类群落背景（鲑鱼养殖型、鲤科养殖型、过渡型）确定的优势鱼类种群 — 尺寸等级（斯特拉勒汇流等级，Strahler confluence row） 水体代码的结构如下： 水体类型代码 + 流域代码（即dce中定义的区域） + 增量编号 DCE报告对应关系：此实体对应WISE中的河流水体（River Water Body, RWBODY）概念。
