1 Reporting sheet 3 QNT_SW Reporting sheet 3 QNT_SW State & quantity of surface water resources Maggie Kossida ETC/W National Technical University of Athens - NTUA Joint EIONET NRC Freshwater & SoE DG Meeting 3 rd October 2007, Copenhagen

2 Serial number: 3 Reporting sheet code: QNT 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: 3 October 2007/ NRC-SoE DG Meeting Author: Maggie Kossida – ETC/W, NTUA Note: this reporting sheet covers both SW and GW resources

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: 3 October 2007/ NRC-SoE DG Meeting Author: Maggie Kossida – ETC/W, 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 Water Scarcity and Drought Communication 18 th July Communication from the COM to the EU Parliament & the Council addressing the challenge of ws & drought in the EU {SEC(2007)993}{SEC(2007)996} Need for more detailed and less aggregated data The issue: reliable info is indispensable for decision-making, shared definitions are necessary, WISE provides the ideal platform to integrate and disseminate such information Way forward: present an annual EU assessment, based on agreed indicators and data provided by MS and stakeholders to the COM or EEA on a yearly basis Date/ event: 3 October 2007/ NRC-SoE DG Meeting Author: Maggie Kossida – ETC/W, NTUA

6 WFD Art. 5 & 2010 National montoring and characteri- zation Eurostat/ OECD Joint Q. 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, drought monitoring Reporting sheet River flow Selected gauging stations Information used by other organisations Water quantity information in WISE Reporting sheet QNT_SW (3) Date/ event: 3 October 2007/ NRC-SoE DG Meeting Author: Maggie Kossida – ETC/W, 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: 3 October 2007/ NRC-SoE DG Meeting Author: Maggie Kossida – ETC/W, NTUA

8 Currently vs. RBD Data on Freshwater Resources Availability River runoff Per capita /country Source: Jucar pilot river basin report Source: Meteonet CHI NTUA Date/ event: 3 October 2007/ NRC-SoE DG Meeting Author: Maggie Kossida – ETC/W, 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 seasonal scale analysis is needed to accurately capture the evolution of water abstractions by source and sector Reporting sheet QNT_SW (3) Date/ event: 3 October 2007/ NRC-SoE DG Meeting Author: Maggie Kossida – ETC/W, NTUA

10 Currently vs. RBD Data on surface water & groundwater abstractions WEI = Total water abstraction/year (as % of long-term FWR in 1990 and 2002) Water use by sectors – RBD Loire-Britany Date/ event: 3 October 2007/ NRC-SoE DG Meeting Author: Maggie Kossida – ETC/W, NTUA

12 B. Surface Water StreamflowGSDaily, Monthly Surface water Reservoir storage (natural and man-made) RMonthly, Annual long term annual average (LTAA) C. 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: 3 October 2007/ NRC-SoE DG Meeting Author: Maggie Kossida – ETC/W, NTUA

13 Water Abstraction by source and sector DeterminandSpatial scale Temporal Scale Volume of freshwater abstraction from surface waterRBDSeasonal (M), Annual long term annual average Volume of freshwater abstraction from groundwaterRBDSeasonal, Annual long term annual average Volume of freshwater abstraction for each sectorRBDSeasonal, Annual long term annual average Sectors: public water supply (if possible separate between domestic, commercial, tourism and industrial purposes) Agriculture manufacturing industry split by abstraction for industrial processes production of thermoelectric power (cooling) Tourism Mining Hydropower Livestock Fish farms Reporting sheet QNT_SW (3) Date/ event: 3 October 2007/ NRC-SoE DG Meeting Author: Maggie Kossida – ETC/W, NTUA

14 main MS comments Water Resources availability: Water abstractions: The code QNT_SW refers only to SW, move GW to QNT_GW as pressure data, also problem w/monthly we need seasonal trends LTAA, ref. period WMO , also specify standards For internal flow (water budget) assumption that MS have calibrated model Tourism and Industry are mentioned twice not always connected to PWSS Data availability, Monthly is difficult, agencies may gather info once a year at least seasonal is important Data availability – not scored as a non delivery Transnational RBD MS part (if not conflict w/ int. conventions) No water scarcity problems communication 18/07, water accounts Methods and standards of measurement should be discussed in more detail Hydrological vs. Calendar year review periods of MS General: Date/ event: 3 October 2007/ NRC-SoE DG Meeting Author: Maggie Kossida – ETC/W, NTUA Austria, France, Hungary, Netherlands, Sweden, Eurostat, WMO

15 Test data exchange for quantity during 2008 JFMAMJJASOND Based on the reporting sheet EEA prepares reporting format (data dictionary and table) for a test data exchange via Reportnet reporting of available info aggregated to RBD level – test scheme; no evaluation of performance EEA analyse the reported information and prepares a background document on data availability and possibilities of streamlining reporting Joint Eionet/SoE Group/Eurostat meeting (quantity experts) with experts, possibly together with COM on drought indicators 2009: Regular reporting of quantity data according to the agreed structure Date/ event: 3 October 2007/ NRC-SoE DG Meeting Author: Maggie Kossida – ETC/W, NTUA
