Structural and tectonic analysis of the mesa in Polická basin
Dergunova, Alexandra ; Hartvich, Filip (advisor) ; Mertlík, Jan (referee)
The area of the Polická basin is in fault and tectonic structures region. Neotectonic and recent long-term movements occur along the geomorphological systems. Endogenous and exogenous processes are the main reason of tectonic activity in the area. Polická basin and its look is influenced by geomorphological processes and represents a perfect region for the study of active fault structures. This area is influenced by physical-geographic characteristics of the region and reflects with long-term processes which determine the development of this area. Two large systems of Polický and Skalský fault run across the selected area. The course of these systems is confirmed by previous studies, and it is indicated in geological maps. The area of faults crosses is area with the most affected geomorphological elements of the relief. Ostaš, Hejda and Kočičí skaly mesas is greatly influenced by Polický fault zone, mainly due to fault close location to the selected geomorphological surface forms. Result of the fault zones pressure is observed on various structures and their form. During the relief and surface features analysis and examination were used various methods, which confirmed the influence of fault zones. The fracture systems showed the same orientation as the Polický fault orientation (SSE - NNW)....

Tidal phenomena in groundwater hydraulics
Ondovčin, Tomáš ; Mls, Jiří (advisor) ; Šembera, Jan (referee) ; Novotný, Oldřich (referee)
Manifestations of the tidal force have been known to humanity since an- tiquity. The oldest extant remarks on the origin of the tidal force are in the Natural History of Pliny the Elder. He also left us remarks on periodic changes of water-level in wells. This phenomenon does not necessarily have to be connected to the proximity of seas. As such, it is a subject of research since the end of 19th century. Exploring the mechanisms with which the tidal force affects the groundwater level requires combining the findings of geology and hydrogeology but also the knowledge of hydraulics and geomechanics of porous media and certain understanding of astronomy. This thesis contribu- tes to the knowledge of the mechanism of tidal oscillations in groundwater measured in a borehole near Teplice nad Metují in Police Basin. It utilizes models based on the knowledge of geological and hydrogeological structure of the surroundings of the borehole. It investigates the relation between the physical properties of porous media and the amplitude and phase of the tidal oscillations and presents solutions of the models.
