3 Water bodies categories  ‘Surface waters’ are inland water bodies: ‘Rivers’ are bodies of inland water flowing for the most part on the surface of the land. ‘Lakes’ are bodies of standing inland surface water. ‘Transitional waters’ are bodies which are partly saline in character as a result of their proximity to coastal waters but which are substantially influenced by freshwater flows. ‘Coastal waters’ are surface water on the landward side of a line, every point of which is at a distance of one nautical mile on the seaward side from the nearest point of the baseline from which the breadth of territorial waters is measured.  ‘Groundwaters’ are all water which are below the surface of the ground in the saturation zone and in direct contact with the ground or subsoil. 1. WFD: TERMS AND DEFINITIONS ( Article 2, Article 5, Annex II) ‘River basin’ is the area of land from which all surface run-off flows through a sequence of streams, rivers and, possibly, lakes into the sea at a single river mouth, estuary or delta.

4 Water bodies nature  ‘Artificial water body’ is a body of surface water created by human activity.  ‘Heavily modified water body’ is a body of surface water which, as a result of physical alterations by human activity  ‘Natural water body’ 1. WFD: TERMS AND DEFINITIONS ( Article 2, Article 5, Annex II) For these water bodies reference conditions for determining the maximum ecological potential are taken For these water bodies, reference conditions for determining the good ecological status are taken

5 Water bodies typologies 1. WFD: TERMS AND DEFINITIONS ( Article 2, Article 5, Annex II)  If system A is used, the surface water bodies within the river basin district shall first be differentiated by the relevant ecoregions in accordance with the geographical areas identified in Annex XI.  If system B is used, values for the obligatory descriptors and such optional descriptors, or combinations of descriptors, are required in Annex II.

6 2. EUROPEAN IMPLEMENTATION STRATEGY  The European Commission decided to create a way on the participation of all Member States and candidate countries. So, the Common Implementation Strategy (CIS) of the WFD was born. As its name establish, the CIS was a springboard to support the implementation of the WFD and all the directives related, since 2000. European Guidance Guidance Document No. 2. Identification of Water Bodies. Produced by Working Group 2.1. WATER BODIES. Guidance Document No. 4. Identification and Designation of Heavily Modified and Artificial Water Bodies. Produced by Working Group 2.2 - HMWB. Guidance Document No. 5. Transitional and Coastal Waters - Typology, Reference Conditions and Classification Systems. Produced by Working Group 2.4 - COAST. Guidance Document No. 10. Rivers and Lakes - Typology, Reference Conditions and Classification Systems. Produced by Working Group 2.3 - REFCOND.  Directive 2007/2/EC establish an Infrastructure for Spatial Information in the European Community (INSPIRE) We must use information on datum and geographic coordinates of European Terrestrial Reference System 1989 (ETRS89)

7 Identification of SWB  For rivers: the hydrographic network has been segmented considering a minimum length of water mass of 5 km, a catchment basin > 10 km 2 and an annual average of basin input water of > 100 l/s.  For lakes, considering those lakes, ponds and wetlands with a surface > 50 ha, regardless of the depth, or with a surface > 8 ha and depth > 3 m.  For transitional waters has been as follows: The internal limit has been the space that is expected to be flooded by high water at spring equinoctial tides which is reflected by the presence of the characteristic halophytic vegetation. The limit to inland waters, has been established using the maximum penetration of the tide in the estuary, which coincides with the boundary between maritime and terrestrial public domain. The limit to coastal waters has been set using physiographic criteria.  As outer boundary of coastal waters is defined by a line at a distance of one nautical mile offshore from the straight baseline. 3. CONSORTIUM EXPERTISE

8 Identification of GWB  For groundwaters: Generally, as a criterion of partition the following aspects have been considered: impermeable layers, effluent river course, influence of human activity, isolation of areas with obvious risk of overexploitation. Some masses have been defined as large wraparound in areas with groundwater supplying more than 50 people, or 10 m 3 /day. 3. CONSORTIUM EXPERTISE Masas de agua río y lago Transitional and coastal WB Rivers and lakes WB Groundwaters

9 Characterisation of SWB types The methodology involves progressive segregation of subsets of the masses, by setting thresholds for variables. An ecological type can be defined by a maximum of six variables, according system B (WFD-Annex II).  These variables have been discriminatory in the case of rivers: specific runoff of the basin and annual average circulating flow, average slope of the basin, latitude and altitude, slope orientation, degree of mineralization, and annual average temperature.  Typing in the case of the lakes was based on the following discriminatory variables: altitude, maximum depth, hydroperiod, humidity, conductivity, alkalinity, surface and geology.  The definition of transitional waters was performed according to hydromorphology which affect biological communities; depth, substrate type, oscillation of the tide, salinity and wave exposure.  In the classification of coastal waters, determinants have been the tidal range and the influence of river flooding periods. 3.

11 Designation of AWB and HMWB 3. CONSORTIUM EXPERTISE  Preliminary designation of Artificial WB and Heavily Modified WB in the river basin characterization (according Article 5) AWB Ponds with a surface area > 0.5 km 2. Reservoirs for urban water supply or for other uses that have a surface area > 0.5 km 2. Water channels that allow the maintenance of dependent ecosystems and having a length > 5 km and an average annual flow of at least 100 l/s. Gravel pits with a surface area > 0.5 km 2. HMWB Dams and waterwheels River bank defences and channels Dredging and extraction of natural products Artificial level fluctuations Changes in the connection with other WB Infrastructures in the WB Ports and port infrastructures Occupation of intertidal zones Artificial beaches Coastal defense infrastructures  Final designation of Artificial WB and Heavily Modified WB in the RBMP (according Article 4.3 and Article 13) - Disproportionate cost analysis

12 Transboundary water bodies coordination Spain - Portugal AGREEMENT: Convention on “Cooperation for the protection and sustainable use of the waters of the Luso-Spanish river basins”, signed in Albufeira, on November 30, 1998. Total river length: 7.157 km3.085 km Area of lakes, transitional and coastal waters: 1.000 km 2 345 km 2 Area of groundwater bodies 22.484 km 2 400 km2 SpainPortugal Population: 1,45 millones hab0,26 millones hab Surface: 55.528 km 2 11.620 km 2 Transboundary masses COORDINATION ASPECTS: ― Water bodies delineation ― Nature of water bodies ― Typology of water bodies ― Pressures ― Monitoring and control networks ― Status of water bodies ― Protected areas ― Program of measures ― Environmental objectives 3. CONSORTIUM EXPERTISE

13  Activity 2.3.1 in Tender: Delineation of the river basin districts.  Activity in the ToR: activity 1.1.2, delineation of the water bodies.  Aim of the activity: The delineation of river basin districts is the first step towards making a characterization report for the basins. Only after this delineation it is possible to make further steps in river basin management planning.  Methodology: It might be that the river basin district does not completely coincide with the hydrological district and in that case important decisions have to be taken. For the river basins districts that were not yet identified, the identification will take place in this activity. This task reaches great importance in the transboundary basin (MERIÇ- ERGENE). River basin delineation 2. EXPECTED WORKS

14  Actions: As a first step, the latest versions of the maps of the hydrological river basins will be collected. As a second step the river basin districts that will be used for WFD river basin management planning, will be identified.  Outputs: - GIS maps showing the hydrological river basins and GIS maps showing the WFD river basin districts. River basin delineation 2. EXPECTED WORKS

15 Water bodies  Activity 2.3.3 in Tender: Review of the delineated water bodies and typology (surface water bodies and groundwater bodies) and review the categories, classes and types of water bodies.  Activity in the ToR: activity 1.1.2 Delineation of water bodies (both surface waters and groundwaters) and typologies thereof in the pilot basins (update).  Aim of the activity: Water bodies are the main management unit in the WFD and also the unit about which the member states have to report. This activity aims at taking these first steps in the river basin management planning. The WFD requires surface waters to be split into categories (rivers, lakes, transitional waters, coastal waters and the groundwater bodies). The next step is to identify the nature of water bodies (natural, artificial and heavily modified water bodies). In a third step, the types of the water bodies will be identified. 2. EXPECTED WORKS

16 Water bodies  Methodology: For all these steps there will be made use of the previous projects where categories and nature of water bodies have been identified and a typology system has been developed. We will use this as a starting point and review this to see if it needs to be updated. It will be done by desk study and, by liaising with experts from the Ministries in Ankara and in the basins. If deemed necessary, revisions will be carried out.  Actions: Desk study and interviews with experts  Outputs: - Report on the provisional delineation of water bodies categories and on the provisional identification of classes and types of surface water bodies. - GIS maps for the four river basins with categories, nature and types of water bodies. 2.
