Local geoheritage: its importance and potential for geotourist and recreational activities (a case study from Lomnicko area)
Kirchner, Karel ; Kubalíková, Lucie ; Bajer, A.
Geodiversity, respectively its valuable part – geoheritage is considered an important resource for the geotourism and recreation purposes. In the C.R., there are a lot of examples of such use of geoheritage: sandstone rock cities, karst areas or polygenetic relief at mountain areas and others. These geoheritage features are usually significant on the national level, their existence assure the attractiveness of the given area, enables the geotourist and recreational activities and support the local and regional development. However, in the local scale, the geodiversity (respectively geoheritage, represented by particular geosites and geomorphosites) can also serve the above mentioned purposes. The paper presents the example from Lomnicko area which can be seen as an “average” area from the geodiversity/geoheritage point of view on the national level, but on the local and regional level, there is a considerable number of geosites and geomorphosites with a potential for geotourism and recreation.

Study of present-day geodynamic processes in the area of Hronov-Poříčí Fault Zone
Stejskal, Vladimír ; Vilímek, Vít (advisor) ; Stemberk, Josef (referee) ; Kirchner, Karel (referee)
The presented PhD thesis deals with present-day geodynamic processes in the south- western part of Broumov Highland, with a special attention paid to the seismoactive Hronov- Poříčí Fault Zone (HPFZ). Compared to the rest of the Bohemian Massif the studied area exhibits relatively increased level of tectonic activity, which is evidenced by local seismicity and by presence of CO2-rich mineral waters. The present-day activity of geodynamic processes is studied by means of various geomorphological, geotechnical, geophysical and hydrological methods. Following processes and features were studied: activity of slope movements, seismic activity, present-day tectonic movements, relations between landforms and joint and fault tectonics. Based on the previous experience obtained by the author in the seismoactive area of Western Bohemia, groundwater observational network was set up in deep boreholes, in order to detect anomalies related to the tectonic activity of the studied area. The thesis represents a contribution to the deeper understanding of the studied area and also a contribution in respect of possible applications of some new methods that can be used in research of zones with relatively increased tectonic activity inside of stable areas of Central Europe. From geomorphological point of view, the...

Dynamics and spatial extension of recent landslides at the foot of Krušné Hory Mts.
Burda, Jan ; Vilímek, Vít (advisor) ; Kirchner, Karel (referee) ; Šilhán, Karel (referee)
Dynamika a rozšíření recentních svahových pohybů na úpatí Krušných hor | Abstrackt 1 ABSTRACT Recent mass movements currently comprise one of the main morphogenetic processes in the extensive anthropogenic relief of the foreground of the Krušné Hory Mountains in the Czech Republic. These mass movements result in several types of deep- seated slope failures, depending on the type of movement, lithological, structural, and geotechnical conditions and the water saturation of the landslide material. This thesis presents broad set of various methods of geomorphology, geophysics, engineering geology, dendrogeomorphology and geodesy in an attempt to fully understand the problem of slope failures in the Jezeří area located at the boundary between the Krušné Hory Mountains and the Most Basin (Czech Republic). An interdisciplinary approach has enabled an in-depth review of both the dynamics and development of recent slope failures as well as morphology and structure of slope failures. There are two sectors - Southeast and Southwest - with different types of slope failures. In the Southwest sector, mass movements occur in thick colluvial mantle and weathered Tertiary claystones. The main factors influencing their development include rainfall culminations, groundwater flowing from the valley of Šramnický Brook and...

Geodynamics development of the Losenice valley, Šumava Mts.
Hartvich, Filip ; Vilímek, Vít (advisor) ; Kirchner, Karel (referee) ; Minár, Jozef (referee)
Topic and aims of the thesis Presented PhD thesis summarizes broadly conceived research of the relief development in the valley of the Losenice, a minor stream descending the steep outer slopes of the Šumava(Bohemian Forest) Mts. The thesis presents an overyiew of the knowledge' gathered throughout ,"u..uí years ofintensive research in the target area, as well as in řts surroundings in the Šumavaand Pošumavíregions. The conception of the thesis is based on a set of reviewed scientific publications, *hi"h were published during the almost six years and which were supported bý several consequent research grants and projects' systemátically almed at th9 research of geodynamics and curient processes in selected parts of the Sumava Mts' The chief aim of the work was to establish a valid hypothesis on the development of the outer s1ope of the ŠumavaMts., particularly in the catchment of the Losenice River' To fulfil this aim' following partial goals were set: ' - t; perform a complete, systematic uld ^ detailed geomorphological mapping of tire target area, analyse the forrns and i.o""'."' wiň particular aim at current and recent dynamics Based on ihe character, intensity and spatial relationships between the processes formulate hypotheses on the development of the area' - to design, build and run a monitoring...

Geodiversity values as a basis for geosite and geomorphosite assessment: a case study from Žďárské vrchy Highland
Bajer, A. ; Kirchner, Karel ; Kubalíková, L.
Paper presents geodiversity values, geodiversity is understood as a set of geological, geomorphological and pedological components, including systems consisting of this components and geological, geomorphological and pedological processes. Geodiversity values are analyzed in relation to ecosystem values (e.g. cultural, functional value). Geodiversity values were used as basis for a methodical approach to geosite and geomorphosite assessment. Methodological approach is presented at selected sites in the top part of the Žďárské vrchy Highland. The acquired results can serve as a basis for geoconservation of PLA Žďárské vrchy, development of geotourism as well as an offer for extension geoeducational activities.\n

Current environmental threats and their impact in the landscape
Zapletalová, Jana ; Kirchner, Karel
Workshop Current environmental threats and their impact on the landscape was organized in the framework of the Strategy AV21 of the Academy of Sciences, the program Natural threats.\nThe papers were oriented both on natural threats (geological and geomorphological threats - slope deformation, erosion, hydrometeorological extremes floods, droughs, biological invasions) and their evaluation and prediction, and social and legal implications of natural and human activities caused by threats and their impacts on the landscape (e. g. changes in the urban environment, anthropogenic impacts in the mining areas). Important topics were focused on the assessment of natural and environmental threats and their solving in selected emergency and crisis situations using geoinformation technologies. \n

Secondary geodiversity and its potential for geoeducation and geotourism: a case study from Brno city
Kubalíková, Lucie ; Bajer, A. ; Kirchner, Karel
Geodiversity is considered to be the most important resource for geoeducational and geotourist activities. Usually the geoeducation and geotourism are developed within natural areas and they are based on the primary geodiversity (natural landforms). Nevertheless, so called secondary geodiversity or man-made/anthropogenic geodiversity (represented by the anthropogenic geosites as old quarries, pits or underground landforms) can be also viewed as a remarkable resource for these activities. Brno city is rich in these landforms; some of them already serve as excursion localities for the university students or they are used for recreation and leisure, some of them are unique (from the geoscience point of view) and they have also certain added values (historical, archaeological or ecological), however, their potential is not fully developed. The article presents examples of these geosites and outlines possibilities of the rational use for the geoeducation and geotourism purposes.
