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.

Barriers preventing the leachate mobility from MSW landfills
Hošek, Michal ; Ettler, Vojtěch (advisor) ; Šebek, Ondřej (referee)
This bachelor thesis summarizes the current knowledge on precautions releted to the leachate migration outside the municipal solid waste (MSW) landfill. It is mainly focused on the characteristics of the engineered barriers, consisting of functional layers and providing better protection of the environment in the vicinity of the landfill with respekt to leached pollutants. These barriers, supported by natural geological barrier in the ground, are typically forming a sandwich construction. Materials called geonets are used for the bottom lining functioning primarily as a drainage layer. They are characterized by their low compressibility tunder conditions of overpressure of waste deposited above. Geomembranes with chemical and mechanical stability serve as barriers against leachates and other emissions. Natural clays are also used due to their sorption capacity, however their application depends on their exact mineralogical composition. Geosynthetic clay liners (GCLs) have permeability at least 4.5 × 10-11 m.s-1 and serve as a protective layer against contamination of groundwater, but also protect the lining in the layers below. To increase the efficiency of this layered system, a drainage layer is commonly added, which also helps to minimize the pressure effects of landfill leachate on the...

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
