Manifestation of flood in June 2013, Upper Lužnice River
Jaček, Matouš ; Šobr, Miroslav (advisor) ; Havlíková, Petra (referee)
This thesis is about progression of chosen fluvial lakes in the upper basin of the river Lužnice. Observed changes were mainly caused by flood in spring 2013. This area is located by national border with Austria. This part of the river is very preserve and almost without human modifications. The Lužnice river is floating throw floodplain creating meanders and also many fluvial lakes. This area is very useful for research in flooding and changes they cause. First part of this thesis is focused on work with literature about fluvial lakes, their changes and characteristic, about floods and their effect on landscape and about the river Lužnice itself. The second part is about measuring and evaluating changes on four fluvial lakes. These lakes were mapped and measured and those measuring were compared to the measuring made before flood in June 2013.

Causation of develpment change of selected fluvial lakes of Lužnice River in profile Základna
Jaček, Matouš ; Šobr, Miroslav (advisor) ; Havlíková, Petra (referee)
The aim of this thesis is to evaluate developement of selected lakes in area Základna in upper Lužnice basin. The area of interest is located in nature reservation Horní Lužnice, which extends from state border with Austria to Suchdol nad Lužnicí. This part of the river is very preserved almost without any anthropogenic influence. Eventhough it is the middle part of the river, it has developed floodplain with meandering belt, which is typical for lower parts of rivers. Because of its conditions, this area is very convenient for observing natural spills and studying fluvial lakes, which occure here in huge amount. First part of this work describes characteristic of the study area, fluvial lakes and natural spills and floods in the area. The main second part focuses on research of selected lakes and their developement. During several field researches the lakes were mapped and measured and soil samples were taken from the lake beds. Furthermore flow in floodplain during river spill was measured and data from automatic surface level sensors were evaluated, which show mutual connections of fluctuations of the lakes and the river. In conclusion the results of measurement were compared with previous theses regarding this area. Main results are that common spills cause clogging of lakes but intense floods...
