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

Deformometric and leveling measurements in the cadastral area of Dětmarovice village in 2018
Kajzar, Vlastimil
2018 - Czech
Institute of Geonics AS CR, v.v.i. in 2001, in connection with the underground mining of coal reserves and its possible influence on the cadastral area of ​​Dětmarovice, Ostrava was asked in 2001 to assess the possible impacts of undermining on the stability of slopes on selected parts of the cadastral territory of Dětmarovice. Consequences of the mining are, among other things, surface drops, which, due to the existing morphology of the terrain in the cadastral area in question, raised the concern that these declines would not further induce sloping movements.\nIn November 2001, a monitoring monitoring network of four individual profiles was built in the locality. On these lines it was recommended to perform deformometric (longitudinal) and leveling measurements at the same intervals. From the subsequent periodic deformometric and leveling monitoring of these slopes before the development of the descending basin into the monitored area and then during the period of manifestation of the effects of the mining, it is possible to determine whether the slope deformations develop at all and then to point out the possible causes of possible movements (morphological-geotechnical and climatic conditions, mining and anthropogenic activity, etc.). Ústav geoniky AV ČR, v.v.i. v Ostravě byl v souvislosti s uvažovaným hlubinným dobýváním uhelných zásob a jeho možného vlivu na katastrální území Dětmarovice požádán v roce 2001 Dolem ČSA o posouzení případných vlivů poddolování na stabilitu svahů na vybrané části katastrálního území Dětmarovice. Důsledkem dobývání jsou, mimo jiné, i poklesy povrchu, což vzhledem ke stávající morfologii terénu v předmětném katastrálním území vyvolalo obavu, zda tyto poklesy nebudou dále indukovat svahové pohyby.\nV listopadu 2001 tedy byla v dané lokalitě vybudována kontrolní monitorovací síť o čtyřech individuálních profilech. Na těchto přímkách bylo doporučeno provádět ve stejných intervalech deformometrická (délková) a nivelační (výšková) měření. Z následného periodického deformometrického a nivelačního monitoringu těchto svahů ještě před začátkem rozvoje poklesové kotliny do sledované oblasti a dále v období projevů účinků dobývání je pak možné stanovit, zda vůbec k vývoji svahových deformací dochází, a následně na možné příčiny případných pohybů poukázat (morfologicko-geotechnické a klimatické přírodní podmínky, hornická a antropogenní činnost aj.). Keywords: deformometric measuring; leveling measuring; Dětmarovice Available on request at various institutes of the ASCR

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.

Structural mapping of exploration boreholes walls within first phase - Safety boreholes for Boxcut
Waclawik, Petr; Souček, Kamil; Vavro, Martin; Kukutsch, Radovan; Ram, S.
2018 - English
Structural-geological analysis, i.e. core fracturing assessment within the boxcut safety\nborehole was carried out on the basis of optical televiewer record evaluation. In general,\noptical televiewer (OPTV) probe provides a continuous, unwrapped, high-resolution digital\n360° image of the borehole-walls oriented towards the cardinal points. This technique\nprovides information about the strike, dip direction, dip angle and depth of foliation, bedding\nplanes and fractures, as well as the frequency, aperture and infillings of fractures. Information\nabout spatial characteristics of structural elements is one of its indisputable advantages and\nallows for subsequent statistical evaluations.\nThe structural mapping of boreholes of Boxcut safety boreholes were carried out within the\ncontract of IG CAS (Contract No. D/18/156/00) GEOMET, s.r.o. (as a customer, contract No.\n01/2018). The aim of the contractual research was the realisation and interpretation of the\nfractures by digital logging of boreholes walls.

Šňupárek, Richard; Waclawik, Petr; Kukutsch, Radovan
2018 - Czech
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. 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.

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.
