The present work gives the characteristics of the bottom macrofauna against the background of the changing chemical composition and pollution of the water of the Vistula in a section of about 45 km of its upper course. A fairly rich and differentiated bottom macrofauna was found. The variability in bottom macrofauna throughout the area was the result of changes in the environmental conditions, while...
An algal growth test was used to show the trophic state of the water of the Dobczyce Reservoir and its direct tributaries. The Dobczyce Reservoir showed a lower trophic level than its affluents. So far, the reservoir has been mesotrophic, but shows a tendency to increase from year to year. The trophic level of its water was less than that of the Goczałkowice Reservoir, which was eutrophic.
The bibliography contains scientific works and popular scientific articles on the River Vistula since the second half of the 19th century to 1993 concerning the following fields were included: morphology and paleogeography of the riverbed, hydrology, hydrogeology, and morphogenetic processes (erosion, transport, sedimentation, siltation of dam reservoirs), chemistry of the water and bottom sediments,...
