European catchments and Rivers network system (Ecrins), rivers - version 1, Jun. 2012
Description
This dataset contains the “river segments” datasets of Ecrins v1.0.
River segments mimic the surface rivers on a simplified way, allowing simple journeying. As for FECs, but completed because of the process, any segment may have 0, 1 or 2 upstream and single downstream. The reason for single upstream is because spurious branching segments have been removed (~160,000) from CCM source during the Ecrins making.
The segments mimic rivers that are cultural, not simply defined objects. The “dummy rivers” (ID is CGENELIN) branches together all the segments which spring is most distant to the sea, then second most distant and connecting to this first set of segments, etc. the “true rivers” are those sets of segments having the same name, disregarding translation (segments on the Rheine, Rhin, etc. have same river ID). Name of true rivers is hosted in the EcrGaz database.
Dummy rivers maybe sorted out as “main drains” that either connect FECs together (continental FECs) or are the most important in a coastal FEC. Main drains are hence the potential population of “WFD large rivers”, since the FEC average size is ~1/10 of the threshold catchment size of main rivers.
The geodatabases contains two feature classes: C_Tr where all segments lines are. This table links to FECs, since a FEC may contain several segments. Feature class C_node contains all nodes, making implicit the flow direction that is identified in C_tr by FNode (from node) and TNode (to node).
