The geophysical survey in area of the mediaeval fortress in Popovice (township Benešov)
Vovsová, Jana ; Dohnal, Jiří (advisor) ; Kněz, Jaroslav (referee)
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).

Geophysical survey of subsurface voids at locality Letonice
Bartášková, Lucie ; Blecha, Vratislav (advisor) ; Skácelová, Zuzana (referee)
The Větrníky national nature reserve, located in the South Moravian region north of the village of Letonice, is one of the largest steppe reserves in Southern Moravia. This whole area is characterized by the presence of both stable and active landslides, and the occurrence of suffosion sinkholes has been monitored there in the long-term. The aim of the thesis was to investigate whether it was possible to observe subsurface phenomena, caused by the washing out of fine rock particles by ground water, by means of geophysical methods. This phenomenon is known as suffosion. The measurements took place in the areas where the suffosion manifestation was very distinctive, that is around two sinkholes that were visible on the surface. In order to identify the suffosion structural-geological causes and their manifestations at a given location, the gravimetric and electrical resistivity tomography (ERT) methods were used in the first stage of the research. Measured data was further processed and geologically interpreted. The gravimetric method has proved suitable when identifying rocks affected by suffosion, in which case we assume that their density is lower than the density of the surrounding rocks. Using the ERT method, it was possible, in the vertical profile, to distinguish the sandy-gravelly sediments...

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

The geophysical survey on archaeological locality on the Malý Blaník hill
Málková, Kamila ; Dohnal, Jiří (advisor) ; Kněz, Jaroslav (referee)
Summary: The bachelor's work consists of two parts. The contents of the first one is the detailed background research of existing information about the archaeological locality on the Malý Blaník hill (geology, petrophysics, history, archaeology and other), supplemented by analysis of prospecting potentiality of different geophysical methods. The core of the second part is the areal geophysical survey of the mentioned locality by means of selected geophysical methods (geoelectrical and magnetometric methods). The contents of this part includes the field measurement, data processing and complex interpretation of the results.

Geophysical survey for deep geothermal energy exploitation at the site Nova Paka
Karousová, Magda ; Karous, Miloš (advisor) ; Kobr, Miroslav (referee)
Title: Geophysical survey for deep geothermal energy exploitation at the site Nova Paka Author: Magda Karousová Supervisor: Prof. RNDr. Miloš Karous, DrSc. Supervisor's e-mail address: karous@geonika.com The topic of this thesis is a literature search of geological, geophysical, and geothermal information about wider surroundings of the area of Nova Paka and a complete geophysical survey focused on mapping of deeper fault zones and verification of Permo-Carboniferous sediments thickness. The area has been preliminarily assessed as promising for the use of deep geothermal energy. It belongs to the south-western part of Krkonoše Piedmont Basin. The bedrock of the basin is formed by Proterozoic metamorphites. Heating of surrounding rocks by intrusions of local volcanics during the Younger Tertiary is considered important for geothermal applications. The cover of metamorphic bedrock by sediments may indicate accumulation of the heat from the bedrock at relatively shallow depths of several hundred meters. Geophysical measurements, namely reflection and refraction seismics, gravimetry and resistivity profiling identified two major fault zones of east-west and northwest-southeast direction. The interpretation of the data obtained by geophysical sounding methods, namely seismic reflection and vertical...
