The frost susceptibility of the soils and materials to subgrade of the pavements
Mašek, Jakub ; Zajíček, Jan (referee) ; Stehlík, Dušan (advisor)
This diploma thesis deals with the issue of the determination of the frost susceptibility of soils in the subgrades of road structures. The theoretical part compares the ways of testing the frost susceptibility in the Czech Republic and other selected countries of the European Union. Furthermore, it also deals with the development of the frost susceptibility index in the Czech Republic. The empirical part focuses on the laboratory testing of the frost susceptibility of the given sample of soil by the direct frost heave method. Moreover, it also deals with the simulation of penetration of frost by the subgrade and the possibility of shortening the length of the freezing during the direct testing the frost susceptibility.

Runoff circumstances and changes in river basins of the Czech Republic and abroad
RYŠAVÁ, Radka
This bachelor thesis is oriented towards the drain, its origin, the elements and factors that affect runoff. It is focused on the hydrosphere, the hydrological cycle, and finally focuses on changes in runoff conditions in the Czech Republic and abroad, depending on the climate and the source water levels of rivers. Between sources of water levels of rivers include, eg rainfall, melting snow, subsurface water, melting glacier. Furthermore, this bachelor thesis deals with the bypass ratio and changes in the basin of the Czech Republic and abroad, and is written in the form of a literature review. It defines the basic concepts of the problem and explains in detail the individual components of runoff. Among the ingredients drain we classify surface runoff, subsurface and groundwater runoff. Further it also describes the hydrological cycle, which can be small or large. The water gets to the earth surface in the form of precipitation, for example such as snow or rain. These collisions affect runoff.

Comprehensive Landscaping in Landscape Management
Humešová, Tereza ; Syrovátka, Oldřich (advisor) ; Květoň, Pavel (referee)
The aim of this work is to create cadastral municipality Lukavec proposals for measures to be focused on stabilizing the drainage conditions in this area. The means for implementation of the proposed measures are landscaping to help develop natural and cultural values of rural, environmental health, and environmental management. The theoretical part deals with the importance of drainage conditions in the country and summarizes the major and most severe impacts that disrupt water regime. The practical part is thoroughly analyzed the selected area and proposed several solutions for improving the basic functions of the landscape. These suggestions may serve as a basis for the development of comprehensive land to land the municipality. Furthermore, the detected status of the implementation plans of common facilities in the village, which has completed a comprehensive landscaping. The aim is also to find out what are the biggest obstacles in the implementation of comprehensive land. The work suggests that the importance of land consolidation as a tool to improve the environment, realizes the little people and the state is only marginal. Inadequate funding source makes the whole process of editing complex is very slow and basically lose the effect, which should yield especially in terms of landscape management. The lack of tools that would make the village-designed common facilities realize is fundamentally wrong. A major problem is too complex and confusing bureaucracy that overly complicates everything, the failure to state a limited local government. Another obstacle is ignorance, indifference and unwillingness of people to undergo this process. It is very important therefore awareness and informing people.

Concept of the revitalization of Nature Reserve Kapličky peat bog and continual monitoring of water regime and vegetation
PAVELCOVÁ, Lenka
The "Rašeliniště Kapličky" Nature Reserve is situated in the eastern part of the Šumava Mts. The reserve contains different peatland vegetation types - ombrogenous and transition bog parts. The area was partly drained due to extensive mining, pasturing and forestry in the past There are variously old drainage canals now. My thesis contains (i) the evaluation of groundwater table fluctuation and its relationship to vegetation composition and the drainage intensity and (ii) the evaluation of plant species composition in differently drained parts of the peatbog. There was strong relationship between actual groundwater table and precipitation, especially in drained areas, the diversity and the occurrence of expansive species were also related to groundwater table. A map of dranaige network inside the peatbog (1 : 3 500) and vegetation map (1 : 4 000) in the ArcMap programme for GIS environment were constructed. In the most drained part of the area the revitalisation measure was proposed {--} installation of wooden dams for blocking of drainage system.

The preparation of revitalisation impact in "Rašeliniště Kapličky"
KOPECKÁ, Ladislava
The peat-bog Kapličky is a nature reserve located on the right shore of the Lipno Dam which we can find in the east part of the Šumava mountains in the Vyšebrodsko nature park. The purpose of my paper is to describe the damage of a part of the peat-bog caused by the human activities in the past. The peat was extracted for the fuel activities. It has led to degradation and the overgrowing of expansive species. Therefore I prepare the foundation for the practical realisation of the peat-bog revitalisation. My paper also includes the monitoring of the ground water level at 14-day-intervals, monitoring of vegetation and its alternations in consequence of water cycle. My paper links to Lenka Pavelcová the magister thesis.
