specific contamination, sediment, cadmiumThe analysis is based on analysis of surface water and sediment chemistry data from the longterm regular monitoring network completed by the own samples taken on the network of profiles set up within the research project. The standard methods were used to analyze the sediment chemistry - water quality classification using the ČSN 757221 standard, sediment contamination classification using the geoaccumulation index and comparison of observed concentrations of heavy metals in sediments. Unlike numerous water basins where the contaminated sediments were washed out and the pollution load levels dropped, the Střela River Basin did not record significant changes in pollution level related to the flood
