Studie odtokových poměrů v povodí bezejmenného levostranného přítoku Svratky řkm 93,8 v k. ú. Ujčov
Mach, Arnošt
The diploma thesis is focused on the assessment of runoff conditions in the selected location for a purpose in form of the proposal complex system of measures. First of all was created literary research on topics like hydrology, forest roads, and measures for water retention. Next were in detail described the natural conditions of the chosen location. Thanks to the field survey were possible to identify critical locations for increased water drainage and determine risk factors. Based on the information gathered evaluated runoff conditions in the studied area and created a rainfall-runoff model in open-source software HEC-HMS. Lastly were designed measures for enabling the safe flow of water and measures for an increase in overall ecological stability.

Identification of suitable places for retaining water in the landscape in the landscape in watersheds of the fourth order in the Trkmanka watershed
Valný, Patrik ; Larišová, Lucie (referee) ; Sobotková, Veronika (advisor)
The bachelor thesis is focused on the identification of suitable places for water retention in the landscape. The evaluated area consists of three selected catchments of the 4th order in the Trkmanka River basin in the South Moravian Region. In the first part of the work the analysis of the area of interest was carried out. Using ArcGIS, USLE2D and DesQ – MaxQ software, erosion and runoff conditions were evaluated to determine the critical points and critical profiles threatening the intravilanias of the municipalities by surface runoff and sediments. Also, the locations of the final profiles that threaten, for example, local roads were identified, these were then subjected to a field survey and photodocumentation was taken. Subsequently, small reservoirs were designed at the assessed and morphologically suitable locations. Finally, from the evaluated erosion and runoff data, a ranking of vulnerability was established.

Blender Add-on for Simulation of Water Erosion
Vlček, Ondřej ; Milet, Tomáš (referee) ; Chlubna, Tomáš (advisor)
The aim of this thesis is adding terrain erosion functionality to Blender. The solution presented here implements hydraulic erosion based on textures and the use of the graphics card. Compared to other existing solutions this add-on utilizes parallel processing, offers an alternate workflow for erosion and creates additional information usable in further rendering of the model.

Posouzení změn erozního ohrožení pozemků v delším časovém horizontu
PICKA, Patrik
The diploma thesis on Comparison of erosion threat to land over a longer period of time aimed to assess and evaluate erosion in a defined time period, namely from 1938 to the current state. The area under consideration was the cadastral area of Kostelec located in the district of České Budějovice near Hluboká nad Vltavou. The work was divided into several parts. The first part was a literature review, in which we deal with the history of the social organization in the Czech Republic du-ring the period under study, we also deal with the issue of erosion and protection against it and last but not least with the land-use regulations. In the second part of the qualifying work we describe the site of interest and deal with the calculation of erosion shear in six periods, namely 1938, 1952, 1964, 1968, 1995 and the present. Soil loss was calculated using the USLE equation of Wischmeier and Smith (1978) and two see-ding practices were used. The first seeding practice was used for the earlier period namely 1938-196 and the second for 1995 and present. The results of the soil loss calculations were summarized and compared and then evaluated. The results showed that land consolidation and appropriate seeding techniques have the effect of reducing soil erosion shear and these practices should be considered. With this knowledge, erosion can be brought under control and to acceptable levels.

Návrh ochrany půdy před vodní erozí v katastrálním území Jinačovice
Kubisová, Sabina
The aim of the thesis "Soil protection against water erosion in the cadastral Jinačovice" is to evaluate the problems of soil erosion and erosion prevention. The work consists of two parts. In the first part the issue of erosion is expressed using relevant printed and electronic sources. The second part deals with the analysis of current conditions and the current status of land use in terms of susceptibility to water erosion. All the erosion factors will be assessed based on the findings. The average long-term loss of land will be evaluated using the universal equation for calculating the USLE soil loss and the degree of erosion hazard to lands will be determined. As a result an erosion control measure (organizational, argi-technical and technical) will be designed and their effectiveness with regard to allowable loss will be assessed.

Hodnocení erodibility vybraných hlavních půdních jednotek (BPEJ) s využitím ke specifikaci faktoru erodovatelnosti v rámci RUSLE
Rosíková, Jana
The soil erosion is one of the most important factor which brings about modification of landscape. Presently, there is more than half of the agricultural land resources endangered in the Czech Republic, in particular by the water erosion. The aim of this thesis is to evaluate susceptibility of selected soil units to the water erosion by force of erodibility factor (K-factor) which is one of the input parameter of Revised Universal Soil Loss Equation (RUSLE). Seven types of soil appearing at agricultural land at the South surroundings of town Brno were selected for the pedological exploration and following determining of the K-factor. On the basis of K-factor figures a map depicting variability of the area from view diversity of susceptibility to the water erosion was made. Soil slaking is closely connected to the soil erosion which characterize the soil from the view of crumbling of soil aggregates and inlay of the soil surface. The susceptibility of the selected soil types to destruction of the soil structure was assessed in this thesis. Further, the task of comparison between present attributes of the soil and the data of Complex exploration agricultural land, which were the base of evaluating dynamic of the development of soil environment, is dealt.
