Development of Pleistocene glaciation of the Czech part of the Šumava Mts. (Case study of the Černé and Čertovo Lakes)
 Vočadlová, Klára ; Křížek, Marek (advisor) ; Kalvoda, Jan (referee) ; Minár, Jozef (referee)
This Ph.D. thesis presents new facts about a paleoenvironmental development of the northern part of the Bohemian Forest (area of Černé Lake and Čertovo Lake) in the Late Pleistocene and Early Holocene. The main goals of the research are: characterize the glacier landforms in the Bohemian Forest and define the variance of these landforms; determine factors influencing formation and development of the glaciation in the study area; describe environmental settings and its changes during deglaciation and in Early Holocene by using environmental proxies. This research proceeds from original data obtained by geomorphological mapping, morphometric analysis and proxy data analyses originated from a sediment sequence in a peat bog in the Černé Lake vicinity. The common attributes of the Bohemian Forest cirques and cirque variability was determined using morphometric and morphologic characteristics of the cirques on the Bavarian and Czech side of the mountain range. These characteristics were compared with other cirques of the Bohemian Massif and other chosen mountain ranges of the world. The cirque overdeepening was defined on the basis of headwall shapes and it emerged that overdeepening of the cirques in the Bavarian Forest and in the High Sudetes reflects a different extent of the Pleistocene glaciation....

Schmidthammer test as a tool for determining of the relative age of glacial sediments
 Procházková, Barbora ; Křížek, Marek (advisor) ; Vočadlová, Klára (referee)
The bachelor thesis is concerned with the use of the Schmidt Hammer as a relative age dating tool of glacigenic landforms. The Schmidt Hammer test is based on the assumption that there is a mutual relation between the degree of weathering of a particular surface and the duration of its exposure. Information about the degree of weathering is expressed by the rebound value (R value). With increasing weathering of a surface the mean R value decreases. Relationship between the R value and the absolute age of a tested surface obtained by numerical dating methods is expressed by the age calibration curve. Principles, conditions and limitations of the Schmidt Hammer test in glacigenous environment were characterized according to the literature. The majority of tested sites were localized in Europe, especially in Scandes. According to the results of statistical analyses, the R value significantly correlates with the altitude and climatic characteristics (mean annual air temperature, mean annual amount of precipitation). For the moraines built-up by granitic material, R value increases with increasing altitude. On the contrary, the R value decreases with the increasing amount of precipitation and mean annual air temperature. Granite proven to be the most suitable material for testing due to small standard...
