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.

Title: Methods of processing macroseismic data and their application to the 2008 earthquake swarm in western Bohemia Author: Bc. Pavla Procházková Department: Department of Geophysics Supervisor: doc. RNDr. Oldřich Novotný, CSc. Consultant: RNDr. Pavla Hrubcová, PhD. Supervisor's e-mail address: on@karel.troja.mff.cuni.cz Abstract: Abstract: This work evaluates macroseismic observations of the earthquake swarm which occurred in West Bohemia in 2008. The first chapters are devoted to the explanation of basic terms, the geological description of the region and the history of earthquakes in the region. The historical development of macroseismic scales and a detailed description of the EMS-98, used for the evaluation of the 2008 earthquake swarm data, are contained in the following chapters. The main part of the present work deals with the manual macroseismic evaluation of the swarm followed by a description of the program for the automatic evaluation of data. The program results were found to agree with the manual evaluation. In the next part there is a detailed description of a program for drawing isoseismal lines. In the appendix the reader can find an overview of macroseismic scales, sample questionnaires and suggestions to improve the Czech questionnaire. Keywords: macroseismical intensity, EMS-98...

Petr Kolínský, DiS. author's e-mail address: kolinsky@irsm.cas.cz departments: Department of Geophysics Faculty of Mathematics and Physics Charles University Prague V Holešovičkách 2, Praha 8 - 180 00, Czech Republic and Department of Seismology Institute of Rock Structure and Mechanics, v.v.i. Academy of Sciences of the Czech Republic V Holešovičkách 41, Praha 8 - 182 09, Czech Republic supervisor: RNDr. Johana Brokešová, CSc. supervisor's e-mail address: johana.brokesova@mff.cuni.cz consultant: RNDr. Jiří Málek, PhD. consultant's e-mail address: malek@irsm.cas.cz keywords: surface waves, group velocity, phase velocity, frequency-time analysis, multiple filtering, tomography, inversion problems, Earth crust structure, Bohemian Massif An overview of surface wave analysis methods as well as of inversion techniques is given. Special attention is paid to the multiple filtering method for dispersion curve estimation, which is described by two different ways in detail. The isometric method is used for dispersion curve inversion and its description and tests are presented. Described methods are further used in applications. The applications show examples of surface wave analysis and inversion for 1D and 2D...
