Version 1, Jun. 2012 - Ecrins is acronym for European catchments and Rivers network system. It is a geographical information system of the European hydrographical systems with a full topological information. Ecrins is a composite system made from the CCM developed by the JRC, Corine land Cover, WFD reporting elements, etc. It is organised from a layer of 181,071 “functional elementary catchments (FECs)” which average size is ~62 km2, fully connected with explicit identifier (ID) relationships and upstream area. Catchments are grouped as sub-basins, river basin districts (actual and functional to meet hydrographical continuity). The catchments are as well organised according to their sea shore of emptying to meet Marine Strategy delineations. Catchments are drained by 1,348,163 river segments, sorted as “main drains” (connecting together the FECs) and secondary drains (internal to a FEC). river segments mimic the natural drainage, however fulfilling the topological constraint of “0,1 or 2 upstreams, single or 0 downstream”. Each segment is populated with distance to the sea, to ease further processing. They are connected to elementary catchments and nodes documented with altitude. Segments are as well documented with a “dummy river code”, fully populated that earmark each segment with the most distant to the outlet in each drainage basin and, everywhere this has been possible, with a “true river” ID based on river naming. A layer of lakes and dams has been elaborated. Lakes polygons (70,847) are taken from Corine Land cover , WFD Art. 13 and in some cases, from CCM “water layer”. Lakes inlets and outlets are set with the segment ID and where relevant, the dams making the lake is documented. All lakes which depths and volume was found have been updated. Version 1.0 here presented still contain some topological errors (e.g. incorrect segment branching), because inaccurate geometry. They are noted and a correction procedure is underway.

Data sources: Statement: Product is based on CCM River and Catchment Database, version 2.1 (vector, lines and points data sets). Coastal definition has been substituted by SeaVox se delineation adjusted to CCM shore line. Lakes polygons are taken from Corine land Cover 2006, XFD Art 13 deliveries and to a lesser extend from CCM water layer. Lakes relevance has been checked against ERM Euroregional maps(layers 2010). River names taken from many sources: ERM, Wikipedia, WFD deliveries and water bodies deliveries, EEA data base on dams, etc. Dams have been taken from several sources: Icold, French ministry of energy, public web sites. Their position has been found by the EEA using a web based tool applied to GoogleEarth, completed by Eionet deliveries. Corrections are proposed by innumerable source, of which EU member states (as provision of the water bodies) and consultants, primarily Pöyry during systematic calculation of discharges at segment level.
