AB  - The applied method - combination of the factor analysis and Fourier transformation is not routinely used in the water management. Due to the fact that the statistic program Prognost is able to do the analysis only from limited number of the quantities, only selected surface water quality indicators were included in the analysis. Therefore it wasn't possible to prove the influence of all eventual natural and anthropogenic impacts in the catchment area that affect the water quality in the reservoir Vranov nad Dyjí. By the selected indicators it was possible to cover especially the effects of the intensive agriculture, the settlement, the recreation (especially from the point of the view of the draining and cleaning of the waste water), climatic influences (precipitation) and partly the nature background. The selected indicators don't evaluate for example the impact of the industry. The water quality in the reservoir is influenced by the water quality from the tributaries and by the biochemical processes in the reservoir itself.
