  14. 14. European Union Water Initiative plus for Eastern Partnership © iStockphoto.com/ansonsaw  WFD covers all waters independent of size and characteristics  Key purpose of the WFD: protect, prevent deterioration or improve the status of aquatic ecosystems  The success of the WFD in achieving this purpose will be mainly measured by the status of “water bodies” (SWB)  SWB are therefore the units that will be used for reporting and assessing compliance with the objectives.  SWB are a tool, not an objective in itself STARTING POINT 14
  15. 15. European Union Water Initiative plus for Eastern Partnership © iStockphoto.com/ansonsaw  WFD: ”Body of surface water” means a discrete and significant element of surface water such as a lake, a reservoir, a stream, river or canal, part of a stream, river or canal, a transitional water or a stretch of coastal water.  CIS Guidance No. 2: The “water body” should be a coherent sub-unit in the river basin (district) to which the environmental objectives of the directive must apply. Hence, the main purpose of identifying “water bodies” is to enable the status to be accurately described and compared to environmental objectives. STARTING POINT 15
  16. 16. European Union Water Initiative plus for Eastern Partnership © iStockphoto.com/ansonsaw  Obviously, the status of the SWB is a key descriptor  If SWB do not permit an accurate description of the status of aquatic ecosystems, it will not be possible to apply the Directive’s objectives correctly STARTING POINT 16
  17. 17. European Union Water Initiative plus for Eastern Partnership © iStockphoto.com/ansonsaw STARTING POINT 17
  18. 18. European Union Water Initiative plus for Eastern Partnership © iStockphoto.com/ansonsaw  At the same time, an endless sub-division of water bodies should be avoided in order to reduce administrative burden   option of aggregation of water bodies, in particular for smaller SWB STARTING POINT 18
  19. 19. European Union Water Initiative plus for Eastern Partnership © iStockphoto.com/ansonsaw  SWB are a tool  SWB have to be based on certain criteria (status, pressures…)  The definition of SWB has administrative (and financial) consequences STARTING POINT 19

  22. 22. European Union Water Initiative plus for Eastern Partnership © iStockphoto.com/ansonsaw  Lakes  Rivers  (Coastal Waters)  (Transitional Waters) CATEGORIES 22 What about impounded rivers?  part of the river SWB?  separate SWB, but HMWB? in the assessment treated as a river?  separate SWB, but HMWB? but “lake character”? in the assessment treated as a river?
  23. 23. European Union Water Initiative plus for Eastern Partnership © iStockphoto.com/ansonsaw Example 1: River Nile / Lake Nasser 23 Lake Nasser (Egypt): A = 5,250 km2 doubtless “lake character” Should be 1 (or more) separate SWB Should be defined as HMWB Assessment following lake methods

  25. 25. European Union Water Initiative plus for Eastern Partnership © iStockphoto.com/ansonsaw Example 2: River Danube 25 Example Danube: chain of impoundments + 2 free flowing sections # Impountments and free flowing sections are separated # Impountments can be grouped to 1 HMWB # Assessment follows river methods
  26. 26. European Union Water Initiative plus for Eastern Partnership © iStockphoto.com/ansonsaw Example 3: Chain of small impountment 26 # Small impoundment with A = 0.2 km2 # no separate SWB, but part of the river # define river section with several small impoundments as 1 SWB

  30. 30. European Union Water Initiative plus for Eastern Partnership © iStockphoto.com/ansonsaw What are types for? Types … … define groups of rivers and lakes with common reference conditions … help to characterize and delineate surface water bodies (SWB) … are the anchor of the ecological classification FROM TYPOLOGY TO RBMP 30 Step 1 Typology of surface waters (System A) Ecoregion Geology Catchment area (rivers) Depth (lakes) Altitude
  31. 31. European Union Water Initiative plus for Eastern Partnership © iStockphoto.com/ansonsaw How to achieve a national typology?  System A defines types by ecoregions, catchment area (rivers), depth (lakes), geology and altitude … good starting points, but rather strict at finer scales  System B permits the use of additional factors and has usually a higher degree of differentiation than System A  Most EU countries use a combination of System A and B by performing a regionalization (System A), as first step, and defining subsequently a proper, fine-adjusted typology (System B) No matter, which system is used – a validation by biology is an absolute prerequisite!  Step 1 – a priori abiotic typology (System A / B)  Step 2 – biological check as a posteriori approach  Step 3 – final definition of types according to the results of step 2 FROM TYPOLOGY TO RBMP 31
