1. Reporting sheet no.3 State and quantity of water resources

2. EEA/European requirements for its assessments on water resources and water use The European information needed in relation to water quantity can generally be described as: How much is there? (Runoff, availability, demands, water stress.........) – Climate change impact on water availability Getting better or worse? Pressures on the environment (abstraction and water use by sectors) Are they working towards targets? such as are water-pricing policies used to provide adequate incentives for users to use water resources efficiently The main policy objectives in relation to water quantity are To ensure the rates of extraction from our water resources are sustainable over the long term and to promote sustainable water use based on a long-term protection of available water resource

3. Framework for assessing water issues

4. The core of information on water availability is the water balance P areal precipitation Qi external inflow ETa actual evapotranspiration Qo total outflow from the territory (Qo = Qo,s + Qo,n) R net recharge into the aquifers C consumptive water use P-ETa = D internal flow (often also referred to as internally generated depth of runoff)

6. Country information on water balance

7. Water availability River runoff Per capita per country

8. Water exploitation index. Total water abstraction per year as percentage of long-term freshwater resources in 1990 and 2002

10. Water Framework Directive (WFD) – assessments change from country basis to River Basin District (RBD) Need for River Basin data on: Available water resource (long term annual average (LTAA) values/annual values) Precipitation (tables; description; trend graphs & maps); Evaporation (tables; description); Renewable water resource/water balance (tables; description; & graphs/diagrams); River run-off (selected gauging stations – LTAA – daily values) Localisation and characterization of reservoirs (e.g. volume) Salinisation plants
