Students' questions about geological map
Flašar, Jan ; Hanus, Martin (advisor) ; Matějka, Dobroslav (referee)
The analysis of student-generated questions (SGQ) is a method to investigate the way of understanding and solving a problem. The style, frequency, type, etc. of the questions can help analyze the target topic, but we can also study differences in understanding and way of thinking among individual groups of respondents. This study was focused on the analysis of the questions generated by high school students working with the geological map of the Czech Republic and the local geological map (map of Prague). The main goal of this study was to find out whether the questions generated by students differ between individual groups of respondents (according to their age, gender, grade, etc.) and whether they differ for individual types of maps. The questions obtained were classified into categories and the frequency of questions in different categories was determined. Furthermore, individual questions were assigned to the corresponding map skills that are necessary for the formulation of the question. Younger students were found to ask significantly more questions about the map display; while older students are also interested in the geological content and the way the map was created. There was also a difference between the geological map of the Czech Republic and Prague. The students were able to obtain...

Late Cenozoic response of the selected fluvial systems of the Bohemian Massif to tectonics.
Flašar, Jan
Despite its intraplate tectonic setting, the Bohemian Massif underwent relatively intense tectonic activity during the Cenozoic. This activity has significantly formed the terrain morphology and river geometry, which can easily be observed from the present status of the streams and relief. Although the effect of tectonics and climate on the terrain morphology has been already researched in previous studies, the effect on the geometry of the river systems has not been surveyed complexly. The author's previous master thesis found two remarkable areas within the Bohemian Massif, where the effect of climate and tectonics on the river system geometry and its changes is very probable - the area of western Bohemia along the Mariánské Lázně Fault and the area of the Novohradské hory Mountains and their foothills. The focus of this thesis is to study the mutual interactions between the tectonic activity and the geometry of selected river systems in the Bohemian Massif. The goal is not only to prove the connection but also to test and evaluate the set of methods that can be useful for localizing those places with recent tectonic activity and which can be applied in similar areas in the future. Both areas - along the Mariánské Lázně Fault and in the Novohradské hory Mts. and their foothills - were surveyed by...

Response of selected rivers of the Bohemian Massif to lithological and structural conditions
Flašar, Jan ; Nývlt, Daniel (advisor) ; Kalvoda, Jan (referee)
Three groups of streams were selected in the area of the Bohemian Massif: the Berounka river with its source streams; the Vltava river with its tributaries the Malše and the Lužnice; the Labe river with its tributaries the Cidlina, the Bystřice and the Javorka. The lithological and tectonical influences to several parameters of the streams were studied. These parameters include: stream gradient, orientation of the stream and sinuosity of the stream. Data were obtained from digital elevation models, aerial photographs, topographical and geological maps. The longitudinal profiles of the streams (in the combination with geological cross-sections), the SL indexes and the gradient/sinuosity graphs were created on the basis of the obtained data. These tools were used for evaluation of the influence of lithology and the tectonics to the streams. The evolution of the streams and the stream-groups was evaluated and compared as well. A strong influence of lithology on the stream gradient was found on most of the analysed streams. The tectonic situation, on the contrary, had strong influence on the orientation of the streams, especially in the resistant rocks. Also, there were selected areas, where was a higher probability of quaternary vertical movements influencing the streams (mountainous areas of the Novohradské...
