O článku:
In accordance with the Directive 2008/105/EC Member States may designate regulatory mixing zones adjacent to points of discharge. Concentrations of one or more substances listed in Part A of Annex 1 of this Directive may exceed the relevant EQS within such mixing zones if they do not affect the compliance of the rest of the body of surface water with those standards. As a basis for designating regulatory mixing zone adjacent to an existing point source is the best knowing of the really hydrodynamic mixing zone very important. That’s the reason, why conductivity in the Elbe River dowstream waste water treatment plant (WWTP) Hradec Králové was measured. Numerical analysis of results is described in this paper. WWTP Hradec Králové is located on the left shore of the Elbe River and belong between one of the biggest Czech Republic´s WWTP of a size in excess of 100 000 PE. The region after complete vertical mixing is of interest in this study. Modeling of the two-dimenzional (2D) contaminant spreading of plume from point source in a river based on the method of Fisher et al. (1979) with correction for the effective origin of effluent is used. Comparison of the numerical results with field measurements shows that this method is useable for prediction of the hydrodynamic mixing zone adjacent to WWTP Hradec Králové in case when the effluent is positively buoyant.
