Tourist interest in illicit zone of ice caves
Nováková, Eva; Kuda, František; Kubalíková, Lucie
2018 - English
Ledové sluje (Ice Caves) in the Podyjí National Park represents one of the most spectacular sites within the area. It consists of the large boulder field and several pseudokarst caverns on the north-western slope of the ridge that are very important from the ecological and geomorphological point of view. The access to the site is restricted for the visitors of National Park as there exists a risk of damage and disturbance of these unique phenomena; tourist can use the marked paths leading around the site, they can reach the top part of the ridge.\nCurrently, there are only several persons who have legal access to the site (employees of the National Park Administration and other researches with the permission issued by NP Administration). However, the installed sensor that counts the passages proved that the site is visited more frequently than it should be. The number of people who visit this site (situated within the first zone of National Park where there is no marked path and so the access is forbidden by decree) is quite alarming. Based on these findings, some proposals for the solution of this unfavourable situation are proposed and other possibilities how to avoid this undesirable phenomenon are discussed.\n Keywords: Podyji National Park; restricted area; passages monitoring Available in a digital repository NRGL

Cultural heritage and geodiversity of landforms in the landscape of the Archdiocese of Olomouc
Kirchner, Karel; Kuda, František; Kubalíková, Lucie; Havlíček, M.; Machar, I.; Pechanec, V.
2018 - English
Within the framework of the NAKI II project – Cultural heritage of landscape of the Archdiocese of Olomouc - research, presentation and management (DGB 16P02B014), we focus on the results that will contribute to the sustainable development of regional cultural identity through applied cultural heritage research in the cultural landscape of the area of interest. As part of the material cultural heritage, we include the landforms that originated from the conscious activity of man - the anthropogenic relief forms. These landforms complement the geodiversity of the landscape and are referred to as secondary geodiversity. Therefore, their identification and interpretation will make it possible to complement and enhance the diversity of cultural heritage and to specify the development of the cultural landscape. The first results from the area of Central Moravia will be presented with the using of the historical maps, the digital model of the relief DMR5G and the field research.

European Countryside and its Perception. Book of Abstracts
Zapletalová, Jana; Vaishar, A.; Šťastná, M.
2018 - English
Rural area was traditionally connected with agriculture. To compare with urban, rural areas were considered to be backwarded, retarded, not worthy of an intensive research. But the situation has changed during the last years. Although cities are still centres of development within the globalization process, people in Europe abandon them as a result of the trends of suburbanization, counter-urbanization, naturbanization. We intend to pay our attention on transformation trends of the European countryside where focusing on more processes occurring there as: transformation from productive to non-productive function,from central planned to the market oriented countryside, from the mono-functional to the multifunctional one, from the national to European and globalized scale. Such a transformation generates many impacts on natural, economic and social processes occurring \nin present European countryside. Their combination creates a set of different countryside types. Keywords: countryside; geography; Europe Fulltext is available at external website.

Stabilita chodeb při dobývání uhlí metodou komora-pilíř ve velkých hloubkách
Šňupárek, Richard; Waclawik, Petr; Kukutsch, Radovan
2018 - Czech
Za účelem ověření napěťo-deformačních projevů dobývání metodou chodba-pilíř v hloubce až 900 m pod povrchem byl implementován rozsáhlý systém geotechnického monitoringu a sledování deformací a pohybu povrchu. Na základě výsledků napěťo-deformačního monitoringu byla provedena podrobná analýza stability chodeb z hlediska konvergence, deformačního chování okolního horninového masivu a funkce použité výztuže ve dvou sledovaných oblastech s rozdílnými geologickými i provozními podmínkami. In order to verify the stress-strain state of mining using the room and pillar method at a depth of up to 900 m below the surface, an extensive system of geotechnical monitoring and observation of deformations and surface movement was implemented. Based on the results of the stress-strain monitoring, detailed analysis of roadway stability from the point of view of the convergence, deformation behavior of the surrounding rock mass and the function of the reinforcement used in the two monitored areas with different geological and operational conditions was carried out.

2018 - Czech
V rámci projektu NAKI II - Kulturní dědictví krajiny Arcidiecéze olomoucké - výzkum, prezentace a management (DGB 16P02B014) se zaměřujeme na výsledky, které přispějí k udržitelnému rozvoji regionální kulturní identity prostřednictvím aplikovaného výzkumu kulturního dědictví v kulturní krajině studované oblasti. Součástí hmotného kulturního dědictví jsou tvary reliéfu, které vznikly vědomou činností člověka - antropogenní tvary reliéfu. Tyto antropogenní tvary doplňují geodiversity krajiny a jsou označovány jako sekundární geodiversita, jejich identifikace a interpretace umožní doplnit a zvýšit rozmanitost kulturního dědictví a upřesnit rozvoj kulturní krajiny. První výsledky z Arcidiecéze olomoucké jsou prezentovány.

Assessment of anthropogenic landforms for the geotourism purposes (case study: Velké Opatovice fortification site, Archdiocese of Olomouc, Czech Republic)
Kirchner, Karel; Kubalíková, Lucie; Machar, I.
2018 - English
The human impact on the relief is often very devastating: natural landforms are modified, damaged or destroyed and the intensity of human-induced processes even surpasses the natural ones. However, people also create new landforms which are interesting from geoconservation, educational, cultural and historical points of view. Thanks to these aspects, they also have a potential for geotourism, geoeducation and recreation. For the assessment of anthropogenic landforms (respectively anthropogenic geosites and geomorphosites), a method based on the concept of geomorphosties and taking into account the holistic approach to geotourism, is proposed. The article presents an example of anthropogenic landforms on geo-cultural site "Velke Opatovice fortification site" situated in the western part of the Archdiocese of Olomouc. Based on the detailed fieldwork, the inventory of landforms and other features, the assessment and some proposals for geotourist use of the site are presented.

Implicit constitutive solution scheme for Mohr-Coulomb plasticity
Sysala, Stanislav; Čermák, M.
2017 - English
This contribution summarizes an implicit constitutive solution\nscheme of the elastoplastic problem containing the Mohr-Coulomb yield cri-\nterion, a nonassociative \now rule, and a nonlinear isotropic hardening. The\npresented scheme builds upon the subdifferential formulation of the \now rule\nleading to several improvements. Mainly, it is possible to detect a position\nof the unknown stress tensor on the Mohr-Coulomb pyramid without blind\nguesswork. Further, a simplifed construction of the consistent tangent opera-\ntor is introduced. The presented results are important for an efficient solution\nof incremental boundary value elastoplastic problems.
