Observation of annual water level changes on lakes in High Tatra Mts.
Sankotová, Tereza ; Šobr, Miroslav (advisor) ; Janský, Bohumír (referee)
The presented thesis deals with annual lake level fluctuation in the High Tatra Mountains. It focuses on the related issue of the hydrological regime of lakes and the process of observation of level fluctuation depending on the genetic type of a lake. On the basis of the available literature, the thesis aims to determine the causes of annual changes in the level fluctuation and to compare these with other alpine lakes. The findings are applied to the lake level fluctuation data originating from the Skalnaté pleso and Hincové Oká. Through a comparison of level fluctuation of lakes in the High Tatra Mountains and the Šumava Mountains significant differences in the annual running of lake levels were found. By contrast, the comparison with the lakes in glacial area, whose hydrological regime is dependent on other physical-geographical factors, show that the annual running level fluctuations are similar. Key words: High Tatra Mountains, lake, hydrological regime

Biodiversity and ecology of makrophytes in selected standing waters in the floodplain of the Lužnice river
DVOŘÁKOVÁ, Olga
This is a field study describing seven backwaters in the floodplain of the Luznice river. The backwaters include alluvial pools, river arms and oxbows which differ in their genesis, morfology, hydrological régime, macrophyte vegetation and chemistry of water and sediments. This study was carried out in the Trebonsko - Protected Landscape Area and Biosphere Reserve, South Bohemia, Czech Republic. The data of species composition of the vegetation on transects of the backwaters are supplemented by water and sedimet analyses.

Evaluation of flood flows in the basin Jenín
LEHOVCOVÁ, Lucie
The aim of this thesis is to evaluate flood flows in the basin Jenín stream. Part of this work is the description of the territory that I prepare from the perspective of the geomorphological, geological, pedological, hydrological, agro-natural, climatic and biotic. For flood flows, I used data for the hydrological year 2009 that I acquired from Thomson weir, where meters are installed. In the first part of this thesis, I conducted field research the functionality of the drainage group. The result is data that recorded performance shafts. In the next section I dealt with the evaluation of quantitative indicators of precipitation, precipitation operation in relation to catchment flows on the cap and providing a critical period in terms of the spring thaw.
