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.

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.

Water exploitation index and trend The maps shows the annual total water abstraction as a percentage of available long-term freshwater resources 2002–2012 (left) and average trend 2007–2012 compared to 2002–2006 (right)
Potential for additional floodplains on the Rhône This map depicts the Rhone river basin land cover within France. This map was created in order to have a higher spatial resolution of this specific area.
Potential for additional floodplains on the Elbe This map depicts the Elbe river basin land cover within Germany. This map was created in order to have a higher spatial resolution of this specific area.
Potential for additional floodplains on the Vistula This map depicts the Vistula river basin land cover within Poland. This map was created in order to have a higher spatial resolution of this specific area.
Water Exploitation Index plus (WEI+) for summer and Urban Morphological Zones (UMZ) The water exploitation index plus (WEI+) compares water use against renewable water resources. The map illustrates the relation between Urban Morphological Zone and the WEI+ at the sub-basin scale for summer months (July, August and September) defined in calendar year.
Water exploitation index plus for river basin districts The water exploitation index plus has been calculated as a multi-annual average per river basin district, for the years 2002-2012, as defined in ECRINS. The ECRINS delineation of river basin districts differs from those defined by Member States under the Water Framework Directive, particularly for transboundary river basin districts.

Water exploitation index plus (WEI+) for river basin districts (1990-2015) This interactive map gives a European overview of water stress conditions. The information presented may deviate from that available in the EEA member countries and cooperating countries, particularly for those countries where data availability is insufficient in the WISE SoE - Water quantity database (WISE 3). Data on hydro-climatic variables were aggregated from a daily to a monthly scale. Water abstraction data were taken from WISE 3 (annual resolution at the national scale), although there are large gaps in the time series. Therefore, intensive gap filling was performed on water abstraction data and proxies were used to disaggregate the data from the national to the sub-basin scale. Information on water use was mainly modelled on the UWWTP capacities, the E-PRTR database and the Eurostat Population change dataset (online data code [demo_gind]) among others. See the methodology chapter for further explanation of gap filling, and spatial and temporal disaggregation, and the data uncertainties chapter for current data availability. This interactive map allows users to explore changes over time in water abstraction by source, water use by sector and water stress level at sub-basin or river basin scale. The WEI+ has been estimated as the quarterly average per river basin district for the years 1990-2015, as defined in the European catchments and rivers network system (ECRINS). The ECRINS delineation of river basin districts differs slightly from that defined by Member States under the Water Framework Directive. The Ecrins delineation is used instead of the WFD because it contains geospatial information on Europe’s hydrographical systems with full topological information enabling flow estimation between upstream and downstream basins, as well as integration of economic data collected at NUTS or country level. In addition to using the WISE SoE - Water quantity database, comprehensive manual data collection was performed by accessing all open sources (Eurostat, OECD, FAO), including national statistical offices of the countries. This was done because of the temporal and spatial gaps in the data on water abstraction. Moreover, a large part of the stream flow data from LISFLOOD has also been substantially updated by the Directorate-General Joint Research Centre. Similarly, a comprehensive update with climatic parameters has been performed by the EEA based on the E-OBS dataset. Therefore, the time series of the WEI+ presented in the current version might be slightly different for some basins compared with the previous version.

Use of freshwater resources in Europe The WEI+ provides a measure of total water use as a percentage of the renewable freshwater resources for a given territory and time scale. The WEI+ is an advanced geo-referenced implementation of the WEI. It quantifies how much water is  abstracted monthly or seasonally and how much water is returned after use to the environment via basins. The difference between water abstraction and return is regarded as water use.
