Verification of the "Čirá - Kopanina" fault existence using morphostructural analysis and geophysical surveying
Findžová, Leona ; Tábořík, Petr (advisor) ; Kašing, Martin (referee)
This thesis focuses on the verification of the Čirá-Kopanina fault existence using morphostructural analysis and geophysical surveying. The verification of the fault zone was based on the analyses of the digital relief model, river network parameters and selected relief features that indicate tectonic activity with a high probability. Based on these analyses, the fault was identified and subsequently verified using geophysical methods. The searched tectonic line passes through the village of Čirá in the Jindřichovice upland district (Krušné hory Mts), continues east of the village of Kopanina and heads south into the Cheb Basin along the Libocký Brook. The direction of the Čirá-Kopanina fault was determined as approximately north-south (348ř - 168ř) and thus corresponds to the north-south orientation of the hypocentres of the West Bohemian earthquake swarms. The Čirá-Kopanina fault zone could thus be a potential source area for the earthquake swarms at the boundary of the Cheb Basin and the Krušné hory Mts. crystalline complex. However, its activity needs to be verified by a further research. Keywords fault, tectonics, digital elevation model, morphostructural analysis, geophysical surveying, Jindřichovice uplands, Krušné hory Mountains

Magnetic susceptibility survey within the archaeological prospection
Lázničková, Eva ; Dohnal, Jiří (advisor) ; Kněz, Jaroslav (referee)
Title: Magnetic susceptibility survey within the archaeological prospection Author: Eva Laznickova Department: Institute of Hydrogeology, Engineering Geology and Applied Geophysics Supervisor: PhDr. RNDr. Jiri Dohnal The work is focused on the use of magnetic susceptibility measurement in archaeological prospection and consists of two interconnected parts. The core of the first one is the background research including basic theoretical and practical knowledge of magnetic susceptibility measurement, with an emphasis on field prospecting and the application of this method in archaeological research. The theme of the second part comprises the areal geophysical survey of the segment of the Hussite siege camp by Novy hrad u Kunratic realized by means of magnetic susceptibility measurement and other selected geophysical methods (magnetometry, conductometry). The contents of this part includes the field measurement, data processing and complex interpretation of the results in connection with all other available information.

Rural settlements in the hinterland of Prague in high and late middle ages. Settlement and agriculture development in suburban regions
Beránek, Michal ; Klír, Tomáš (advisor) ; Kypta, Jan (referee)
Master's thesis deals with the micro-region Klánovice's forest and its surroundings on the eastern edge of the City Prague. This area has not been given comprehensive attention yet. The findings are based on a critical review of the humble written and archaeological sources relating to the concerned area. In addition, was made, analysis of archaeological excavation, which was carried out on the deserted village Hol and also geophysical survey from the same site. Based on the lessons learned to better classify and discuss the role of this area in the hinterland of high medieval Prague. Keywords: deserted village, Klánovice forest, Hol, geophysical survey, ceramics, agricultural margins land, high middle ages

Geophysical methods for localization and exploration of deserted medieval villages
Vošvrdová, Eliška ; Dohnal, Jiří (advisor) ; Kněz, Jaroslav (referee)
This bachelor thesis deals with geophysical methods used for localization and exploration of deserted medieval villages. It's comprised of two closely related parts: theoretical and practical. First of which, the thesis reviews the current knowledge about deserted medieval villages, how to locate them and describes practical application of selected geophysical methods such as magnetometry, geoelectrical resistivity survey (symmetric resistivity profiling, electrical resistivity tomography) and electromagnetic (ground penetrating radar, dipole electromagnetic profiling). In addition to the explanation of basic principles and practical use of the methods in archaeological prospection, this part of the thesis presents particular examples of structures and objects that are being sought around the areas of deserted medieval villages. The second part is experimental and its main aim is to describe geophysical research of a selected area called Štítary u Městce Králové. The primary purpose of research was to localize relicts of deserted medieval village. This part of the thesis examines the preparation proces, implementation of the terrain measurment, the data processing and, most importantly, the interpretation of the final results. Key words: archaeology, deserted medieval villages, geophysical methods,...

Geochemical and geophysical prospection of an archaeological locality ( (Hillfort Prague - Vinoř)
Novotná, Žaneta ; Dohnal, Jiří (advisor) ; Klír, Tomáš (referee)
SUMMARY: The diploma thesis is focused on application of natural science methods - geophysics and above all geochemistry - in archaeology. Geophysical and geochemical techniques have become an integral part of non-destructive archaeology over time. While geophysical methods have been practiced in a wide array of archaeological surveys for many decades, geochemical methods have been used to a greater extent up to in recent years. In addition, the application of geochemistry in archaeology is, in most cases, limited only to the analysis of phosphates in soil applied to small spatial units. The potential of geochemistry in dealing with archaeological issues remains still unused due to the limited understanding of the context. This is also reflected in the absence of publications that would allow a good-quality interpretation of geochemical data in connection with archaeology. Geophysical and geochemical procedures were applied during the survey of the selected area in the locality of Hillfort Vinoř, located on the northeastern outskirts of Prague. The aim of this survey was to contribute to the widening of the existing knowledge of the locality with an emphasis on the wider context. Two methods were chosen for the geophysical survey - dipole electromagnetic profiling (DEMP) and electrical resistivity...

Contactless conductometry for shallow parts of geological medium
Podolník, Jan ; Dohnal, Jiří (advisor) ; Kněz, Jaroslav (referee)
The task is focused on the issue of contactless conductometry for shallow parts of geological medium and it consists of two connected parts, search and experimental. The first part includes fundamental theoretical principles of contactless conductivity measurement, summary of presently manufactured electromagnetic devices (ground conductivity meters) and finally it presents the potentialities of using conductometry for detection and monitoring of contaminants. The basis of the second part comprises the field test measurements with the instrument CMD (producer GF Instruments, s.r.o. Brno) on the selected locality, namely for several depth levels. The contents of this part include the field measurement, data processing and complex interpretation of the results in connection with geological conditions of the locality, petrophysical knowledge and with the stability of the device.

The Master's thesis "Geophysical survey in the area of the mediaeval fortress in Popovice" is divided into two parts. The first part is theoretical and summarizes the possibilities of using electrical resistivity tomography method (ERT) in archaeology. The second part deals with the actual geophysical prospecting in the area of the mediaeval fortress in Popovice (Benešov county). General information on the locality including geological setting, past geophysical exploration in the area, history of the object, archaeological findings and overview of construction development are addressed in this part, prior to the description of the field measurements. Methods used on the site are then specified: symmetrical resistivity profiling, dipole electromagnetic profiling, electrical resistivity tomography and ground penetrating radar. Subsequently, the process of field measuring in the area of the fortress is described and the data processing methods are discussed. The results of these measurements and their interpretation on the basis of compiled geophysical maps and sections are presented finally. Key words: geophysical survey, archaeology, fortress in Popovice (Benešov county).
