Watercourses (SVAR2012): View service

Watercourse lines, also known as flow lines, are lines through lakes, watercourses and watercourses describing the network. Each flow line has a unique id (running distance identity) and belongs to a watercourse with watercourse identity and name. EU_CD is an attribute coordinated with water authorities for the identification of water bodies or other waters. A water body is a delimited and significant the presence of surface or groundwater, in this case surface water; Under the WFD, it is defined as: the minimum quantity for the description and assessment of water, excluding groundwater. One the surface water body belongs to a special type, has a specific water quality and is deemed to be exposed to a specified level of impact. Some smaller lakes that form part of the district’s basic structure and environmental monitoring but not meeting the selection criteria to be classified as water body is called: “other water” and also has an EU_CD. However, these are encoded by N in column VF and are: that means no water body. Non-water flow lines have EU_CD starting with the characters “NW”.
