Deterministic (Census) All reference sites 15 stations designated under 77/795/CEE Decision Now all reference sites. In the near future only a probabilistic selection. Reference network in both cases 15 stations designated Selection criteria depends on RBD: Higher frequency than required by WFD has been defined for the first River Basin District Management Plan in order to satisfy information needs every year. 4) Estimation of transboundary pollutant loads and emissions to the sea Deterministic Main transboundary rivers - Catchment size (> 1 Km2) - Flow (> 1 m3/s) - Major load bearing rivers (control 9% of loads: OSPAR criteria) SURVEILLANCE MONITORING Subprogramme 1 (Overall assesment) Number of WB to monitor Probabilistic design of sampling: i.e. Simple random sampling To estimate a parameter u n = α 2 To estimate trends 2 σ d n u α/2 σ d (1-α) Number of stations (WB) needed Level of significance for a given level of confidence (i.e., u equal to 1,65 for a level of confidence of de 9%) (Statistical tables for a normal distribution).

18 OPERATIONAL MONITORING - Type of statistical design and statistical criteria of design Type of statistical design: Deterministic Target population: All water bodies which on the basis of either the impact assessment or surveillance monitoring are identified at risk. Water bodies in which programmes of measures have been applied to assess changes in the status of such bodies. Water bodies into which priority substances are discharged. Number of WB to control: All water bodies of the target population with possibilities of grouping. There is no need to control water bodies at risk for classification of status because its status is worse than good. Such water bodies will be assessed to establish programmes of measures.
