Possible assessment of runoff variability at experimental catchments in Šumava Mountains
Kalkus, Jan ; Kliment, Zdeněk (advisor) ; Královec, Václav (referee)
Main aim of the thesis is to make an outline of possible indicators of runoff variability and options how to use these indicators to compare catchments of different attributes, based on literature review. Further is mentioned general information about experimental catchments and sorts of researchers which were made there. Applicative part aims at application of selected methods for central Šumava catchment (Ptačí creek, Rokytka river) and upper reaches of Blanice river (paired catchments of Tetřívčí and Zbytinský creek). Results of this part confirm some of previous research results made in the same locations. Keywords: runoff variability, runoff regime, experimental catchment, Šumava Mountains

Use of stable hydrogen and oxygen isotopes in hydrology of small catchments in the Czech and Slovak Republic
Šanda, M. ; Vitvar, T. ; Holko, L. ; Blažková, Š. ; Bůzek, F. ; Císlerová, M. ; Fottová, D. ; Kostka, Z. ; Kulasová, A. ; Kvítek, T. ; Šnytr, O. ; Tachecí, P. ; Tesař, Miroslav ; Vícha, Z. ; Žlábek, P.
The contribution summarizes the development of isotope hydrology and hydrogeology in the Czech and Slovak Republic over the past 40 years. Records of 18O and 2H in nine experimental catchments and their interpretation provide a description of runoff component mixing from various soil and rock environments, as well as a calculation of mean water residence time of 7 to 25 months. The 18O and 2H content in two profiles of the Jizera River and two boreholes in the lower reaches shows little communication of river water with the groundwater supply resources in the Lower Jizera area; the communicaton increases with pumping intensity. The 18O and 2H content in wetlands and groundwater in two catchments of the Jizera Mts. shows the differences in recharge to the wetlands via groundwater or precipitation. The isotope hydrology and hydrogeology perspectives in the ČR and SR include capacity building, cooperation of laboratories and conjunctive use of izotopic and hydrogeochemical approaches.
