2 Serial number: 3 Reporting sheet code: QNT_SW Reporting sheet name: State and quantity of water resources What should be reported? Why is it needed? How should it be reported? Data Determinands Treatment of data before reporting Station selection and information Date/ event: 12 June 2006/ 6 th SOE DG meeting Author: Maggie Kossida - NTUA

3 Date/ event: 12 June 2006/ 6 th SOE DG meeting Author: Maggie Kossida - NTUA Activitities in relation to water quantity Task 8, 9, 10 Working Database -Checking of 2006 delivery - Test 2007 update Eurostat data tables Task 5 SOE Reporting sheets Task 26 CSI18 Update (use of freshwater resources) Task 23 Background notes 1)Household water use 2)Tourism water use 3) Agriculture water use 4) Water pricing 5) Desalination & reuse CIS WG on Water Scarcity 2008 report on water resources Task 14 Climate change & water demand (CC impact on flow regime, sectoral water demand etc.) 2008 report on climate impacts Task 11 SOE data flow in WISE Task 30 IRENA Update (water use, water abstr, agr. share of water use) Outputs

4 Reporting sheet QNT_SW (3) Overall purpose: provide representative periodic assessments of the status and trends in the availability and use of freshwater resources adequately monitoring the progress along with the European policy objectives improve water facts today to facilitate policy decisions and issues Three main questions to adequately capture the drivers, pressures and state of freshwater resources are important: What variables are useful? What spatial and temporal scales are appropriate? How to build on existing effort and where to expand? What is needed ? Date/ event: 12 June 2006/ 6 th SOE DG meeting Author: Maggie Kossida - NTUA

5 Reporting sheet QNT_SW (3) Why is it needed ? Adequately formulate indicators Assess the state & trends of the WR and associated pressures Monitor the progress with European policy objectives Broader assessment of specific water-related issues in the relevant conceptual ecosystem frameworks Assess the impact of specific sectors, driving forces & responses The information needed in relation to water quantity can generally be described as: Drivers: natural availability of WR, hydrometeo parameters Pressures: water demand, water abstraction by source & sector State: assessment of trends by source Impacts: ecosystem integrity, use value Need for more detailed and less aggregated data Date/ event: 12 June 2006/ 6 th SOE DG meeting Author: Maggie Kossida - NTUA

Reporting sheet Water resource and abstraction Aggregated by RBD Water resource and use at country level SoE reporting -Trend in water abstraction - Water use by sectors - Indicators Hydrological services Reporting sheet River flow Selected gauging stations Information used by other organisations Water quantity information in WISE Reporting sheet QNT_SW (3) Date/ event: 12 June 2006/ 6 th SOE DG meeting Author: Maggie Kossida - NTUA

7 Reporting sheet QNT_SW (3) How should it be reported ? 1.Data on Freshwater Resources Availability Status and trends in the hydrometeorological parameters and the hydrological freshwater resources budget Spatial aggregation: RBD level (scaled down to reflect spatial variability of WR and support adequate analysis) Temporal aggregation: monthly basis (allow distinguishing seasonal patterns and assessing dry periods within a hydrological year, as well as investigating additional indices such as the Dry season flow index, WRI) Some additional data will be collected on surface water storage volume for the natural or man-made reservoirs in the RBD, and groundwater levels and storage for the main aquifer systems (comprehensive of the water resources availability trends over long-term and deeper assessment of water scarcity issues) Streamflow data will be also compiled for selected gauging stations on a daily time step (provide a more complete national picture and assess additional hydrological trends, such as flood patterns, changes in the 7-day low flow etc.) Date/ event: 12 June 2006/ 6 th SOE DG meeting Author: Maggie Kossida - NTUA

8 Currently vs. RBD Data on Freshwater Resources Availability Date/ event: 12 June 2006/ 6 th SOE DG meeting Author: Maggie Kossida - NTUA River runoff Per capita /country Source: Jucar pilot river basin report Source: Meteonet CHI NTUA

9 How should it be reported ? 2. Data on surface water & groundwater RBD level enhance the assessment, complimentarily with the OECD/Eurostat work, by including the aspects of seasonality, temporal and spatial variability Annual assessments at national level do not reflect regional trends and patterns… thus a regionalization at RBD level is required, and a monthly scale analysis is needed to accurately capture the evolution of water abstractions by source and sector Reporting sheet QNT_SW (3) Date/ event: 12 June 2006/ 6 th SOE DG meeting Author: Maggie Kossida - NTUA

Groundwater Groundwater levelMASMonthly, Annual Changes in groundwater storageMASMonthly, A nnual long term annual average (LTAA) Water Resources Availability Streamflow at selected gauging stations_Specifications: Daily data for the representative gauging stations (minimum of 10 years continuous measurements is desirable). Each representative GS and year should be described by a set of summary statistics (mean, maximum, mean annual minimum flow (MAM), etc.) Representative GS: such as downstream stations at the main catchments and main tributaries. Stations may also be selected to describe natural flow such as stations unaffected by reservoirs or water abstractions. One GS/1000 km2 may be used as an indicative density Reporting sheet QNT_SW (3) Date/ event: 12 June 2006/ 6 th SOE DG meeting Author: Maggie Kossida - NTUA
