Analýza, interpretace a prezentace kulturní krajiny - povrchové krasové útvary jako součást genia loci Moravského krasu
Opletalová, Kateřina
Bachelor's thesis on the topic: Analysis, interpretation and presentation of the cultural landscape - surface karst formations as part of the genia loci of the Moravian Karst under the supervision of Ing. Eva Žallmannová, Ph.D. The work is focused on selected sinkholes in the Moravian Karst PLA. The introduction contains a general description of karst phenomena and a general overview of sinkholes. The following field survey methodology is described here. Part of the work is also devoted to the design of a tourist route through selected sinkholes. The thesis presents the results in the form of tables and maps in the appendices.

The potential of karst conduits development in the area between the Úštěcký and Košátecký stream basins and the delimitation of the catchment areas of the main spring groups
Pátek, Karel ; Bruthans, Jiří (advisor) ; Kůrková, Iva (referee)
The main objective of the work was to determine the extent to which the rocks forming the outcrops in the area between the Úštěcký and Košátecký Creek basins are subject to decay and karstification. This was studied by means of acid leaching. The study area contains some of the most important groundwater reserves in the Czech Republic and understanding the local conditions is crucial for proper groundwater management. Samples were collected from exposed rock outcrops in the vicinity of Košátecký Creek and the soluble component (calcite content), degree of disintegration, rock density and porosity were determined by leaching the samples in 10% HCl solution. In general, it was observed that at a low calcite content, the degree of disintegration of the samples during leaching was low, but the porosity of the samples increased. When calcite content exceeded 40%, most samples started to disintegrate at least from 50%. The results showed that there are layers with a high calcite content and high disintegration degree in the study area, which may host karst preferential pathways. Such layers are thin and embedded in thick layers of quartz sandstone. In the second part of the work, the distribution of hydrogeological basins was estimated on the basis of a new base flow map, measured stream flows and groundwater...

Contaminant transport in karst environment and tracer tests in karst system near Turnov
Malechová, Kateřina ; Slavík, Martin (advisor) ; Weiss, Tomáš (referee)
Karst areas are an important source of drinking water but they are at significant risk of contamination. The theoretical part of the thesis focuses on different types of contaminants, their sources and their ways of transport in karst areas. Due to the high velocity of water flow in karst areas, most contaminants are transported rapidly and spread over long distances. Therefore, it is necessary to actively address the issue of contamination in karst environments, focusing mainly on contamination prevention and water flow studies. In the practical part of the thesis, a quantitative tracer test was carried out in the karst system near Turnov using NaCl as a tracer. The measurements confirmed a high water flow velocity of several kilometers per day and the dominance of advection as the main transport process. These results are consistent with previous research. The connection between the sinking stream Šálení smyslů and the Slapy and Bezednice springs was also reconfirmed, with a total recovery of around 50%. This implies that water from the Šálení smyslů most likely flows to other, yet unknown, locations. No communication with the Bartošova pec cave or with the springs used as a source for the local brewery has been demonstrated, so the question remains where all the water from the sinking stream...

Effect of effluent from wastewater treatment plants on karst rivers
Schrimpelová, Kateřina ; Gruberová, Eva (referee) ; Malá, Jitka (advisor)
Karst rivers are special type of rivers because of their hydrography conditions. They usually flow from non-karst area and as soon as they reach in to the karst area they disappear underground. There, they flow through cavities until they reach the surface again. The aim of this thesis is to assess the impact of water outflow from wastewater treatment plant on karst rivers. The study was done in the central area of CHKO Moravský kras where the impact of two WWTP on a cave system Rudické propadání – Býčí skála is evaluated. As a part of this study a half-year monitoring was carried out, which consisted of water sampling once every two weeks. In total, 13 water samples were taken from 8 sampling points. Also 4 additional one-time samples were taken from the cave system. Moreover, flow rate, temperature, conductivity, oxygen concentration and pH were measured at the sampling point. Afterwards, the content of undissolved solids, CODCr, BOD, N-NH4+, N-NO2-, N-NO3-, P-PO43- and total phosphorus were determined in the samples. The change of parameters in time and during the flow in the river was observed from the measured values. The balance of pollutants in particular parts of the river was calculated. The outflow values from waste water treatment plants were compared to the emission limits for surface waters and the parameters of rivers were compared to the environmental quality standards. According to the results, it can be observed that the water quality improves after passing through the cavities. It was proven that the outflows from the observed waste water treatment plants are negatively influencing the water streams. The most serious problem is the wash up of sludge from WWTP Rudice and its consequent sedimentation in the river and/or outflow to the Rudické propadání.

Effects of Municipal Wastewater Treatment Plant at Lopac Sinkhole Cave System
Ondruš, Martin ; Gruberová, Eva (referee) ; Malá, Jitka (advisor)
The aim of this thesis is to assess the impact of water outflow from wastewater treatment plant on karst rivers. The study was done in the northern area of Moravský kras protected landscape, where the impact of WWTP Ostrov u Macochy on a cave system Lopačské propadání was studied. As a part of this study a half-year monitoring was carried out, which consisted of water sampling every two weeks. In total, 13 water samples were taken from 7 sampling points. Moreover, flow rate, temperature, conductivity, oxygen concentration and pH were measured at the sampling point. Afterwards, the content of undissolved solids, COD, BOD, N-NH4+, N-NO2-, N-NO3-, NKi and total phosphorus were determined in the samples. The change of parameters in time on the sampling points and further along the flow of the river was evaluated from the measured values. The outflow values from waste water treatment plants were compared with the emission limits for surface waters and the values of river water parameters were compared with the environmental quality standards. It wasn’t proven that the outflow from the observed waste water treatment plant is negatively influencing the water stream. The most serious problems are: -The WWTP was designed for treatment of sewage from Ostrov u Macochy, which involved separate sanitary and storm sewers. After finishing the WWTP, a uniform sewer was built. -High concentration of total phosphorus on the outflow from WWTP. -Poor quality of Lopač brook water already before the outflow vent from WWTP.

Map of the Dratenická Cave Surroundings in Moravian Karst
Hanuš, Vojtěch ; Švábenský, Otakar (referee) ; Weigel, Josef (advisor)
The aims of my diploma thesis are the design of a map of Drátenická cave surroundings in the Moravian Karst in the 1:500 scale with details utilizable by speleologists and the examination of a map of 1945 depicting the region of Drátenická cave. The thesis includes an elaboration of the theoretical foundations relevant for the fulfillment of the aims and the descriptions of the geodetic and processing procedures. The outcome of the thesis is the planimetric and altimetric survey, a new digital map of the region and the final examination of planimetric and altimetric components of the map of 1945.

Balková, Marie
This diploma thesis deals with description of the karst and its typical phnenomenons with emphasis on surface figures sinkholes. Further, it dicribes the airborne laser scanning (ALS) technology, data collection and processing procedure and utilization for the puropose of terrain depressions indentification based on the researches and processes of foreign experts. From these available studies, the most suitable methodics is chosen and applied to Digital Elevation Model of 5th generation (DEM 5G) data. The results of this aplication are compared with available sinkholes databases kept in the PLA Moravian Karst office and own terrain research.
