Subject aims expressed by acquired skills and competences

The goal of the Subject is to clarify the status of Hydrobiology of the Life sciences. In addition, students learn the basic and functional aspects of aquatic ecosystems, understand and be able to analyze the structure of community of standing and flowing waters, functional and trophic relations and regulatory mechanisms that determine the types of aquatic ecosystems, evaluate the types and degree of loading of waste water treatment and other anthropic influences (problems of acidification, eutrophication of water) and finally become with the issue of revitalization of water streams and rivers.

Summary

After completion of this subject students will understand basic characteristics of water environment, the evolving and categorization of freshwater communities, the pollution of water ecosystems by wastewater and some additional issues (acidification, eutrofication etc.).

Subject syllabus:

1. Limnology, the emergence and development of Hydrobiology, geological and biotypological distribution of water, the water cycle in nature. 2. Groundwater - rocks and their properties, types of rock permeability, circulation of groundwater, the distribution of groundwater, chemical and physical properties of groundwater, groundwater recovery. 3. The process of groundwater pollution, animal responses to various types pollution, ways of detecting pollution of groundwater remediation methods groundwater. 4. Standing water - the basic physical and chemical properties (density, viscosity, surface tension, electrical conductivity, redox potential, pH, alkalinity, hydrostatic pressure, solar radiation, transparency, color, heat mode). 5. Circulation of substances - oxygen cycle, biogeochemical cycles of carbon, forms CO2 in water, carbonate equilibrium and its significance, alkalinity of water, nitrogen cycle in water, N2 fixation, assimilation of NH4 + and NO3-, nitrification, denitrification, the cycle of phosphorus in the water and ecological importance P limitation of water, sulfur water cycles, the cycle of iron and manganese, silicon and its forms in water, organic substances dissolved in water. 6. The structure of stagnant water biota. Settlement extreme stagnant water (bogs, fens, periodic pools). 7. Running water - the basic physical and chemical properties. Life environment and structure of biota (plankton, drift, phytobenthos, zoobentos, nekton), changes in the longitudinal profile of communities in natural flow conditions. 8. Pollution of surface waters - sources and types of pollutants (Mineral and putrid sludge, toxic substances, radioactive substances, warmed waste water, waste water and oily substances and petroleum products, waste water with pathogenic organisms). 9. Self-cleaning water flows and physical and chemical processes of self-cleaning, the influence pollution on the occurrence of aquatic organisms, successional stage self-cleaning, dealing with emergency situations in the flow. 10. Assessment of purity of surface waters - saprobic systems. 11. Changes in flow and the influence of flow adjustments. 12. Acidification of aquatic ecosystems-sources of pollutants, and short-term long-term changes in water acidity, the extent of acidification, catchment and water chemistry, development phase of acidification, direct and indirect effects of acidification on aquatic biota, indication of acidification, acidification examples. 13. Eutrophication of standing waters - definition, extent, causes eutrophication, ratio of nutrients, phosphorus source for eutrophication, development of primary producers, reduction of external nutrients. 14. Waste water treatment - waste water, origin, composition. Biological wastewater treatment (septic tanks and septic tanks, irrigation and soil filtration, stabilization tanks and ponds, reed). Wastewater treatment technology (1 mechanical stage, 2 biological level - bio spray, rotary biodiskové reactors, activation, anaerobic technology, sludge and sewage gases, 3 tertiary treatment plants - secondary treatment plants). 15. Water Biology - water resources, and leads pretreatment of raw water, Water plants, evaluating the effectiveness of water treatment, organoleptic failure of drinking water quality requirements for drinking water, hygiene of drinking water.
