This diploma thesis elaborates on the influence of constructed wetlands on macrozoobenthos of the respective recipients. Constructed wetlands near the town of Hostětín were chosen for this research project, as well as its recipient Kolelač river delta where cleaned water is drained into. The report also contains analysis of Kolelač's stream area which took place during April 2013 under the auspices of the TA02020128 project by T.G.Masaryk Water Research Institute Brno. Investigation was performed in five sites labeled L1-L5. Of these, L3 was placed in the vicinity below the outfall of constructed wetlands. The research involved a one-time collection of quantitative and qualitative samples of macrozoobenthos by the so called PERLA method. Different characteristics for each facility were analyzed in order to carry out a comprehensive survey. This included for example: abundance, amount of taxons; diversity; taxonomic composition of microzoobenthos; as well as other ecological factors of Kolelač stream quality affected by the constructed wetlands. Macrozoobenthos' studied using abiotic factors demonstrate that the L3 drainage area in closest proximity to constructed wetlands is more polluted than other locations. Analysis by a multi-metric index ranked L3 into the 3rd group, indicating that a medium ecological water quality was present, whereas other locations are ranked into the 5th group with the highest ecological quality of water.
