Hydromorphological survey of the Bilina River
Kyselka, Jan ; Matoušková, Milada (advisor) ; Langhammer, Jakub (referee)
The main aim of this thesis is assessment and presentation of results of the hydromorphological survey of the Bílina river, which belongs to rivers with the biggest anthropogenic impact in the Czech Republic. The method Hydroecological monitoring (HEM, Langhammer, 2007) was used for the survey. This method is compatible with the Water Framework Directive 2000/60/EC. 53 parts of the river with the lenght 31,99 km were assessed. The thesis also includes assessement of the rainoff regime and information about protection of water ecosystems and sources in the Bílina river basin. Keywords: hydromorphology, HEM, Bílina river

Changes of ecosystem loads in longitudinal profile of anthropogenic polluted river

Disertační práce Změny zátěže ekosystému v podélném profilu antropogenně ovlivněného toku Kateřina Kohušová Changes of ecosystem load in longitudinal profile of antropogenically influenced river ABSTRACT To determine anthropogenic load of the Bílina river ecosystem we monitored concentrations of selected heavy metals (As, Cd, Hg, Pb, V, Zn) and specific organic substances (PAH, PCB, HCH, HCB, DDT) in three different matrices: surface water, biofilms and sediments. In the longitudinal profile of the river, four sampling profiles were determined (B1 - B4), mapping different parts of the river. The monitoring took place from 2005 to 2008. Concentrations of the substances monitored in surface water showed a decrease in load compared to the values from ten years ago. The concentrations found in surface water showed clear tendency of pollution in the longitudinal profile; the load increased downstream and profiles B3 and B4 mid- and downstream had the highest concentration. In the case of some concentrations of substances in surface water there is a trend of the majority of values being below the detection limit by the given methods of analysis. This shows a decrease of load in the river but the positive trend was invalidated by variations in maximum concentrations. Even though these variations were rare and...

V příkladové studii na Bílině se ryby na úrovni společenstva projevily jako dobrý a rychlý indikátor ekologického stavu toku, avšak pro indikaci chemických látek v řece je nutné hodnotit specifické parametry na úrovni jedince.
