Learning outcomes
|
To give an overview of basic processes in cycling of nutrients (C, N, P, S), organic matter (primary production, humic substances), and other elements (Si, Fe, Mn, Al) within the ecosystem of "catchment-reservoir/lake" and show possibilities how to evaluate these processes.
Insight into influence of catchment and its characteristics (natural conditions, anthropogenic factors) on composition of surface waters, on aquatic ecosystems of reservoirs and lakes and water quality.
