This interactive map allows users to explore changes over time in water abstraction by source and water use by sector at sub-basin or river basin scale. The WEI+ has been calculated as the quarterly average per river basin district, for the years 2002-2014, as defined in the European catchments and rivers network system (ECRINS). The ECRINS delineation of river basin districts differs from that defined by Member States under the Water Framework Directive, particularly for transboundary river basin districts.

Waterbase - UWWTD: Urban Waste Water Treatment Directive – reported data Urban Waste Water treatment Directive concerns the collection, treatment and discharge of urban waste water and the treatment and discharge of waste water from certain industrial sectors. The objective of the Directive is to protect the environment from the adverse effects of the above mentioned waste water discharges.

Waterbase - Water Quantity Waterbase is the generic name given to the EEA's databases on the status and quality of Europe's rivers, lakes, groundwater bodies and transitional, coastal and marine waters, and on the quantity of Europe's water resources

Water statistics (Eurostat) Population connected to waste water collection and treatment systems. Yearly data on waste water treatment (connection rates of resident population to waste water treatment and treatment capacities of waste water treatment plants), collected biennially by means of the OECD/Eurostat Joint Questionnaire - Inland Waters.

European catchments and Rivers network system (Ecrins) 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.

Water use and environmental pressures Europe's waters are affected by several pressures, including water pollution, water abstractions, droughts and floods. Major physical modifications to land (e.g.drainage, soil erosion and floodplain changes) and to water bodies (e.g. channelisation and barriers) also affect morphology and water flow.
