7. JÚCAR PRB FIRST RESULTS

8. Adaptation of Jucar River Basin Hydrologic Information System to WFD requirements Adaptation of monitoring networks to WFD requirements Characterization of surface water bodies Characterization of groundwater bodies Economic Analysis Analysis of pressures and impacts Main activities

9. Adaptation of Jucar River Basin Hydrologic Information System to WFD requirements

11. Adaptation of monitoring networks to WFD requirements

12. Improvements on groundwater water level monitoring network Existing monitoring sites (160) New monitoring sites (129) Aquifers

13. Improvements on groundwater water quality monitoring network Existing monitoring sites (127) New monitoring sites (25) Aquifers

14. Biological monitoring network 254 points In operation from 1999

15. Biological Quality elements Macro invertebrates Fishes Diatomeas Macrophytes Hydromorphological quality elements Hydrological regime Flow velocities Structure and substrate of the river bed Structure and condition of riparian zones Physic-Chemical quality elements Temperature Oxigenation Salinity Acidification Status COD BOD5 Phosphate Potassium Chloride Sulphate Calcium Magnesium Sodium Silica Monitoring network biological indicators

16. Ecological status classification: Macro invertebrates Index (BWMP’) at Jucar river

17. Characterization of surface water bodies

18. Júcar river at Alzira Rambla de Cervera del Mestre Rambla de la Castellana River typologies

19. Types of river reaches Identification of type of river reach (field work by river police)

20. Digital terrain model (100 m x 100 m) Delineation of surface water bodies: rivers Drainage network with basins > 100 l /s and drainage area > 10 km2

21. Surface water bodies Rivers Coastal waters Reservoirs

22. Characterization of groundwater bodies

23. Aquifers Shared aquifers (Segura) Shared aquifer (Tajo and Ebro)

24. Preliminary estimation of available groundwater resource

25. Differences between resources and abstractions in Júcar River Basin aquifers (year 2000)

26. RESOURCE AVAILABLE RESOURCE Environmental restrictions Environmental Restrictions : Ecological discharges, groundwater outflows to the sea Rate of overall recharge of the body of groundwater less the long term annual rate of flow required to achieve the ecological quality objectives WFD introduces the concept of available groundwater resource

27. Environmental minimum flows associated to each aquifer

28. Differences between resources and abstractions (year 2000) Differences between available resources and abstractions (year 2000) Comparison between resources and abstractions

29. Economic Analysis

30. Available resources for water supply: River Basin Authority. Water use fee (for canals) Water regulation canon (for reservoirs) Water distribution: Municipalities and User Communities. Sewage and water treatment: Autonomous Government. Control of discharges: River Basin Authority Charges and Fees

31. Main river basin hydraulic infrastructures (cost recovery)

32. Canon for water regulation (Benageber and Loriguilla Reservoirs) Hydropower stations

33. Main users of Benegeber and Loriguilla reservoirs

34. Non recovery due to Flood Regulation is approximately 33%. Recovery of regulation canon for Benageber and Loriguilla reservoirs

35. Analysis of pressures and impacts for surface water and groundwater bodies

36. Morphological alterations Identification of small dams (field work by river keepers) Validation at Water Planning Office (use of ortophotos) Incorporation to GIS

37. X,Y=714.668, 4.415.295 X,Y=715.114, 4.415.080 Morphological alterations Validation of small dams and river channelling

38. Accumulated Irrigated area (has) Digital terrain model (100 m x 100 m) Irrigated surface Accumulated irrigated surface
