Atmospheric deposition as a possible source of surface water pollution (Results of the project, part 2. – polycyclic aromatic hydrocarbons)
From October 2020 to September 2021, in two forest micro-catchments in the Czech Republic, the quality of wet atmospheric deposition (bulk and throughfall) was monitored simultaneously with the surface water quality in the local watercourse, humus, and the moss species Pleurozium schreberi. An evaluation is presented of the 15 polycyclic aromatic hydrocarbons (PAHs) burden of the above-mentioned matrices. The first site was chosen in the Beskid Mountains in the Moravian-Silesian region, in the cadastre of the village of Bystřice in the upper basin of the Suchý stream (altitude 590 to 835 m a.s.l.). This area is affected by industrial activities. The second reference site was chosen in the Bohemian-Moravian Highlands near Košetice observatory (altitude 520 m a.s.l.).
Atmospheric deposition as a possible source of surface water pollution (Preliminary results of the project, part 1 – heavy metals)
Concentrations of selected heavy metals in collected atmospheric precipitation
and surface water were monitored at pilot sites in the Jizera Mountains, the Moravian‑Silesian
Beskydy Mountains and the Bohemian‑Moravian Uplands (CZ) over the course of one year to determine the significance of the impact of precipitation on surface water quality in an otherwise relatively low anthropogenically influenced environment. The measurements show that for some
metals, atmospheric deposition in heavily loaded areas can cause significant inputs to streams and reservoirs, but the resulting balance is strongly influenced by the environment and its past loading.
Drinking water supply as well as its quality form one of the basic pillars of modern society. This corresponds to the goal of the International Water Association (IWA) – good, safe and drinkable water, which enjoys consumer confidence and can be not only drunk without fear, but in which the consumer also appreciates its taste and… Read more »

The Výrovka river basin as a suitable area for monitoring and comparing hydrological and landscape characteristics
The Výrovka river basin, as a compact area covering 542.5 km2, is very suitable for monitoring hydrological characteristics and comparing them in different landscape types. It is located on the border of the Lower Vltava and Upper and Middle Elbe sub-basins, extending in a range of 175–555 m above sea level, with a total of six landscape types according to the typology of the contemporary landscape of the Czech Republic. Simultane-ously, there is a varied mosaic in terms of geological subsoil and soil types. There have also been major changes in land use in this basin, mainly due to intensive agricultural activity and related watercourse modifications and amelioration. Monitoring activities within the project SS02030027 ”Water systems and water management in the Czech Republic in conditions of climate change” are currently taking place in the Výrovka river basin.
Environmental protection is one of the important societal needs. Appropriately oriented applied research is also necessary for its fulfillment.
River Basin Management Plans data processing enables obtain not only detailed summary of results, but also appreciates relations between partial results and their significance to achievement of specified objectives.
Surface water body typology category river in the 1st and 2nd cycle of River Basin Management Plans and its consequence to ecological status assessment
Surface water body delineation and setting a typology are one of the initial steps during Water Framework Directive implementation (WFD) . The first delineation and typology was prepared in 2004–2005 for the first plans, but all the results were significantly changed in the second cycle 2009–2010.
Reporting of River Basin Management Plans under Water Framework Directive in 2016 in the Czech Republic
In 2015 the River Basin Management Plans (RBMP’s) for the 2nd planning cycle under Water Framework Directive were designed and approved. According to the Directive the copies of the RBMP’s were sent to the Commission by 22. 3. 2016.
