Tomíčková, Lucie ; Křížek, Marek (advisor) ; Létal, Aleš (referee)
The diploma thesis analyzes the positional and morphometric characteristics of tors in Hrubý Jeseník Mts. and their surface weathering. As a part of the distance mapping, tors' spatial distribution was determined using 5th generation digital elevation model and aerial orthophotos. Selected morphometric information (elevation, slope, aspect, and solar radiation) were determined using the digital elevation model. During field work, descriptive morphometric properties of tors (maximum height, width, and length) and their surface weathering were evaluated. Surface weathering was analyzed using Schmidt Hammer test and the method of measuring the veins and weathering pits morphological characteristics. Based on statistical analysis, the weathering characteristics were evaluated in relation to tors' morphometric and topographic characteristics. A total of 511 tors were identified in Hrubý Jeseník Mts. by distance mapping. Tors occurrence and distribution is related to the slope, lithology, orientation, and solar radiation. The majority of the tors are located below the summit at elevation of 900-1000 m a. s. l. There is more than 60% of metagranite and gneiss tors. Tors' height ranges from 1.6 to 30 m. Surface weathering have been measured in 58 tors. Microforms morphology measuring revealed the influence...
