Thermal and moisture regime of patterned ground in the High Tatras
Pechačová, Blanka ; Křížek, Marek (advisor) ; Engel, Zbyněk (referee)
6 ABSTRACT Thermal and moisture regime of patterned ground is closely associated with the presence of the regelation phenomenon. Generally, the regelation includes all processes leading to the water freeze-thaw alternations in soil or bedrock. As a result of cyclic freezing and thawing of soil water under specific conditions, processes, such a moisture migration, ice segregation or frost heaving, operate. Termal and moisture regime is the main factor of these processes and consequentely, of the patterned ground formation. The submited diploma thesis is concerned with thermal and moisture regime of patterned ground in the High Tatras. The main aims of the thesis was to characterize thermal and moisture regime of patterned ground, to evaluate and confront the patterned ground regelation activity depending on the diverse soil depths and different types of the patterned ground and to evaluate the soil temperature relationship to the air temperatures, soil moisture content and the water level regime of the nearest lakes. The partial purpose of the thesis was to assess the applicability of different methods of the regelation cycle determination based on the soil temperature measurements. During the study period 2007 - 2012 the regelation activity of sorted paterned ground (Hincove oká, Lúčne sedlo and Skalnaté...

Regelation of patterned ground in the High Tatras.
Pechačová, Blanka ; Křížek, Marek (advisor) ; Voják, Karel (referee)
Regelation (freeze-thaw cycles) is the collective term used for a process of alternate freezing and thawing of water and solutions into the soil or bedrock. The series of geomorphological and pedological processes such as migration of soil water, formation of segregated ice or frost heaving, is connected with regelation. Condition of freezing-thawing process is a phase transition of water that leads to an important phenomenon - a release or consumption of latent heat. This phenomenon can be observed from the data obtained by measuring the temperature in the soil profile. In the present bachelor thesis, here are investigated sites of sorted patterned ground (Hincovo pleso, Lučné sedlo) and earth hummocks (Kopské sedlo) in the High Tatras for the purposes of the study regelation process. In addition to detailed description of the physical-geomorphological processes associated with phase changes of water in patterned groud, the main aim of the thesis is to set regelation cycles and their characteristics using different methods for determination of regelation on the basis of temperature measurements in patterned groug of the foregoing locations. The results indicate differences in regelation in the individual shapes within the locations, among the sites, but also between different types of patterned groud -...
