Přirozená retence vody v krajině versus výstavba retenčních nádrží
SEDLÁČEK, Jan
This work is focused on natural water retention in landscape. There are described basic principles of water behaviour in soil, comparing of water retention in different types of land-use and anthropogenic influences including flood-protection and land-use changes. In the practicle part, there is described an experiment which focuses on comparing of retention potential of land-use changes in catchment of water dam Orlík with retention capacity of the dam. This work includes GIS analysis which focuses on areas of each type of land-use in the Orlík catchment.

ResPublica/Civitas Socialis - Strachotín
Ildža, Lukáš ; Klein, Pavel (referee) ; Nový, Vítězslav (advisor)
The aim of the project is to design a public building in the place, where phenomena of Pálava mountains, reflecting water surface and wine tradition meet. It is right in the area of Strachotín village. Project is trying to harness the power of these qualities to create a special attractive house. But also, the house is showing the viewer new perspective on these entities, which would not be seen without it. The location and concept of this wine house is strengthening the link between village and Pálava reflected in water. Therefore, the main part of interior is oriented exactly on the axis between these two poles. Secondarily, house contains the small museum of local history. In terms of technical aspects, we are dealing with the floating house, which is not affecting the building of dyke in no way.

Long Term Discharge Prediction in River Hydrometric Profile
Šelepa, Milan ; Menšík, Pavel (referee) ; Marton, Daniel (advisor)
The diploma thesis is focused on the long term prediction of mean monthly flows in hydrometric profile for purposes of reservoir control optimization and optimization of reservoir systems. Discharges were predicted using by artificial neural network method. Predicted flows were statistically evaluated by relevant coefficients and then compared with the measured flows for given river hydrometric profiles.

The dynamics of sexual reproduction and ephippia production of Daphnia in reservoirs
VANÍČKOVÁ, Ivana
This thesis focused on the dynamics of the sexual reproduction of microcrustacean Daphnia (Cladocera, Anomopoda). Sex in Daphnia is induced environmentally after rounds of asexual parthenogenesis in favorable conditions. The onset of sexual reproduction and the occurrence of sexual individuals was investigated with respect to their distribution in the water column and clonal structure. The produced sexual eggs were genotyped and their density and distribution in sediment were analyzed. The impact of massive floods was investigated. The role of sexual reproduction in stable habitats and its relevance and importance for Daphnia communities is further discussed.

Ecological demands of the selected planktonic algae and cyanobacteria from the order Nostocales. Light intensity and temperature optima of the water-bloom dominant species in the ponds and reservoir in the Czech Republic.
KOHELOVÁ, Hana
This thesis is aimed on cyanobacterial water blooms. It deals with the composition of cyanobacterial water blooms, factors which cause its emergence, effect it has on environment, termination of cyanobacterial bloom and ways of how to restrict it. My thesis contains the chapter devoted to the cyanobacterial bloom characteristic, which gives them advantage over other organisms in plankton and over other cyanobacteria as well. It also contains general description of fishponds and reservoirs and locality description (fishpond Svět and Rod, water reservoir Římov, Jihočeský kraj), which were the sources of species tested in this experiment. The aim of the experiment was to find out the optimal temperatures and light for the growth of seven strains of cyanobacteria and one species of green alga. The experiment was conducted by cross-table gradient of temperature and light method (KVÍDEROVÁ a LUKAVSKÝ, 2001. Data of the strains growth in different combinations of temperature and light intensity was processed in program Statistika (ANONIMUS, 1996). Valence of each strain has its maximum and minimum values. In their mean, there is an optimum for the growth. Charts depicting maximal-minimal values and optimum of strains for temperature and light were created in Microsoft Excel. Details between temperature and light demand of strains were tested by PCA analysis in program CANOCO 4.5 and visualised by CANODRAW (TER BRAAK a ŠMILAUER, 1998). It resulted in particular values, which are comparable with similar laboratory tests.
