Assessment of Long-Term Soil Loss on Selected Slopes Using the USLE Equation
SUTTIKHANA, Itthanan
This study presents an assessment of long-term soil loss on selected slopes in both the Czech Republic and Thailand utilizing the Universal Soil Loss Equation (USLE). Soil erosion poses a significant threat to agricultural productivity and environmental sustainability worldwide, highlighting the importance of understanding erosion dynamics and implementing effective mitigation measures. The research focuses on experimental plots in the Czech Republic's South Bohemia region and Thailand's Sadao district, examining factors contributing to soil erosion and evaluating the efficacy of soil conservation practices. Results indicate notable disparities in soil erosion rates between the two regions, influenced by varying environmental conditions, land use practices, and topographical features. Despite comprehensive soil conservation measures recommended by the Department of Land Development in Thailand, challenges in implementation persist due to limited resources and expertise. The study underscores the urgent need for tailored soil conservation strategies to address specific erosion challenges faced by each region. By integrating site-specific data and recommendations, policymakers, land managers, and researchers can collaborate to promote sustainable land management practices and safeguard soil resources against erosion threats. Continued monitoring and assessment efforts are crucial to track the effectiveness of mitigation measures and ensure the long-term resilience of ecosystems and agricultural systems.

Comparison of the effects of rain on the old and new rainfall simulator
Banzetová, Diana ; Vrba, Jan (referee) ; Milerski, Rudolf (advisor)
This dissertation is focused to modeling of the rainfall in laboratory conditions by the rainfall simulator invented in VUT Brno. Results of the measuring are compared with measured values of the original rainfall simulator located in VVU VSH VUT in Brno by the Kninicky village in 1976-1980. Dissertation verifies rightness of substituting the natural rain with the rainfall simulator on bare soil in the original location, kinetic energy of the rain drops is substituted with the energy gained from the weight of the drops - the flow. Generally the dissertation determines the possibilities of the rainfall simulator's current location.

Set of arrangements in Javornický stream floodplain for Rosnička pond water quality improvement
Špaček, Ondřej ; Hubačíková,, Věra (referee) ; Hyánková, Eva (advisor)
This thesis deals with the projection of water management and erosion control measures in the Javornický stream floodplain to improve water quality in the Rosnička pond near the town of Svitavy. In the teoretical part, the author summarized current practices in the areas of small river restorations and protection against soil erosion in the Czech Republic. In the practical part, the analasis of the area was first made, including the analysis of natural conditions, hydroecological monitoring of watercourses according to the HEM 2014 method and quantification of soil loss conditions according to the USLE method. Then, revitalization measures on the Javornický stream were designed to improve the self-purification of water and the restoration of ground water in the floodplain, as well as two variants of erosion control measures on agricultural areas to reduce the input of sediments into the hydrographic network. Finally, conceptual and technical recommendations for the implementation of these measures were formulated, as a basis for planning and decision-making of the political leadership of the town of Svitavy.

Flood prevention by using biotechnical measures
Pospíšil, Jan ; Pavlík, František (referee) ; Dumbrovský, Miroslav (advisor)
This thesis investigates the design of complex systems-natural flood control measures in the area of the cadastral municipality Jeseník nad Odrou. Based on the analysis and exploration of the territory, it was suggested a possible solution by erosion and hydrological GIS tools. To identify areas at risk of erosion and runoff conditions were used a digital elevation model, Wischmeier-Smith equation and model DesQ. Subsequently, the effectiveness was evaluated by comparing the results navžených measure erosion and runoff conditions before and after measures.

Meziplodiny a zaplevelení obilnin
Pluschková, Zuzana
The aim of this master’s thesis was to determine the types of weeds in intercrops and subsequent cereals, to evaluate changesin weeding and to estimate the long-term effects of intercrops on cereal weeding. The weeding rate was evaluated using a numerical method. In the company Hoštická a. s., weeding was observed in various mixtures of intercrops and subsequently cultivated spring barley and maize. In a field experiment carried out at the experiment station Ivanovice na Hané weeding was observed in a barley monoculture after a sown intercrop and after skimming. The results were processed using statistical methods. Weed species were also divided according to different criteria (according to biological properties, according to origin, according to invasive status and according to harmfulness). The results show that monoculture of barley can increase the species representation of weeds. In the long term, intercrops can suppress some types of weeds. Intercrops allow the sprouts of the previous crop to emerge and prevent weeding of subsequent crops. As the diversity of intercrops increases, the list of ecosystem services expands.

Možnosti uplatnění technologií zakládání porostů polních plodin do nezpracované nebo částečně zpracované půdy v zemědělském podniku
Výmola, Ivo
The bachelor thesis focuses on the design and possibilities of using of minimum tillage systems, specifically strip tillage technology with simultaneous injection of fugate from biogas plant into the soil profile for maximum utilization of this fertilizer. In the theoretical part, emphasis is placed on the introduction of conventional tillage and the types of minimum tillage systems and the evaluation of their advantages, but also their possible negative impacts. The practical part focuses on the evaluation of the current technology of soil tillage and establishment of maize silage crops and its economic evaluation and the design of a new technology of strip tillage with simultaneous application of this fertilizer to the soil profile. This practical part is based on data from the enterprise Zemědělská akciová společnost Nivnice. Finally, an evaluation of the return on investment and the benefits of this technology for the enterprise was carried out.

Porovnání PK a KN držby pozemků a posouzení erozního ohrožení při postupném zvětšování ploch orné půdy
KUBEŠ, Tomáš
This thesis deals with the topic of soil erosion on arable lands in the Czech Republic. The theoretical part consists of evolution of evidence of real estates in the Czech lands and furthemore, it describes the process of water erosion. In the second part of this thesis, the estates of Land Cadastre and Cadastre of Real Estate were compared in terms of erosion jeopardy. Based on the results, the impact of size of an estate on water erosion was evaluated.

Soil and terrain changes as a result of increased erosion and accumulation processes in selected locations
Votýpka, Jan ; Šefrna, Luděk (advisor) ; Zádorová, Tereza (referee)
Soil and terrain changes as a result of increased erosion and accumulation processes in selected locations Abstract Colluvial soils are formed in areas with increased intensity of soil erosion. Colluvial soils originate as a result of their position in terrain, they are usually found in places where has accumulated erosion material. Very often they are to be found at the around of slopes. Their accumulation horizon is deeper than 25 cm with a great amount of organic carbon buried in it. In my diploma thesis I will attempt to take a closer look at three locations, each having different types of dominant soils. The aim of this diploma thesis is to rebuild the original shape of the terrain before the beginning of the soil erosion process. Keywords: colluvial soil, soil erosion, soil accumulation, land use, digital terrain model (DTM)
