Upon successful completion of this course, students will have acquired basic knowledge concerning the running water ecosystems , springs, rivers and torrents.
They will understand the cycle and the distribution of water in nature, the classification of rivers and river zones.
They will have knowledge about the abiotic and biotic factors that are important for running waters, including general information about their living organisms that colonize them, ie the plankton, the benthos and the fishes.
They will have gained knowledge about the food chains, the productivity and the trophism of running waters.
