Course content

Development of the river ecosystems concepts. Holistic approach to study freshwater ecosystems. Evolving perspective on running water , the history of research and their classification. The consequences of anthropogenic activities in the context of the modern theory of the functioning of river ecosystems. History of the study of running waters. Classification of running waters. Zone conception ( Fric , 1872, Illies & Botosaneanu 1963). The impact of anthropogenic activities on the river ( Berg 1948) . A holistic view of running waters - 60th to 70th years - energy flow , balance of organic matter of individual sections of streams ( Hynes 1970). The interaction of spatial and temporal perspectives . The interdisciplinary character of the study of running waters - 80th to 90th years. The River Continuum Concept ( Vannoy et al . , 1980) , additional views and criticisms of RCC . Related concepts - Nutrient Spiralling ( Newbold et al . , 1981) , Serial discontinuity (Ward & Stanford 1983) , Stream Hydraulics ( Statzner & Higler 1986) , Patch Dynamics (Townsend , 1989, Pringle et al . 1988) , Flood pulse ( Junk et al . 1989) , four -dimensional nature of film products ecosystems (Ward 1989).The final chapters of the course are devoted to the issue of circulation of substances in running waters. Theoretical lectures are followed on the practical experience gained during the all-day field exercise in the beginning of the course.
