Use of the USLE 2D Model to Assess the Impact of Anti-Erosion Measures on the Extent of Potential Water Erosion in the Research Area of Sobotište
Tomaščík, Matúš
The article focuses on assessing the impact of anti-erosion measures on soil water erosion implemented at the Sobotište research site, covering an area of 68 ha. The anti-erosion measures consist of two water retention grass ditches located in the lower part of a slope and a change in the management of the entire slope. The assessment twas conducted by comparing slope conditions before and after implementing anti-erosion measures using the Universal Soil Loss Equation (USLE) and the USLE2D sub-model, which calculates the LS topographic factor. The modelling was conducted in the ArcMap software environment with a digital relief model resolution of 1 × 1m and the LS topographic factor calculation algorithm according to the author McCool [1].

Study of landscape proposals in the Hlinsko near Přerov Cadastral Area
Špaček, Stanislav ; Holomek, Michal (referee) ; Paseka, Stanislav (advisor)
The aim of this bachelor thesis is to characterize the area of interest, the municipality Hlinsko, to define the decisive factors determining the flood hazard of the intravillage of the municipality, to determine the critical points and the corresponding critical profiles, to define the erosion assessment areas and to define the erosion hazard on them. Subsequently, propose erosion protection organisational, agrotechnical and technical measures and appropriate erosion protection seeding practices. In the introductory part of the work, the existing knowledge on the subject and the procedures for determining the surface runoff values and the erosion hazard rate were defined. Subsequently, an analysis of the study site was prepared and in the final part suitable water management and erosion control measures were proposed.

Study of runoff and erosion conditions in the Ketkovice cadastral area
Buršík, Lukáš ; Uhrová,, Jana (referee) ; Sobotková, Veronika (advisor)
This Diploma Thesis is focused on the analysis of the Ketkovice cadastral area in terms of runoff and erosion conditions. The QGIS software was chosen for the analysis. For this reason, instructions for this software are prepared, focusing on runoff and erosion conditions, as an appendix to the Diploma Thesis. Other software programs used are USLE2D and DesQ-MaxQ. The first part deals with the analysis of the area of interest. The second part deals with the problem itself, at first the methods used to determine runoff and erosion conditions are introduced, then anti-erosion measures, at the end of this part the software programs used are briefly described. The last third part is devoted at first to the evaluation of runoff and erosion conditions before the design of the measure, then to the design of the measure itself, finally to the evaluation after the design of the measure. In case of erosion conditions, two variants of calculating long-term soil loss are considered before and after the proposed measures. In the first variant, a constant value of the factor R=40 MJ.ha.cm.h is considered in the Universal Soil Loss Equation and in the second variant this value is increased with respect to the climate change.

Řešení protierozní ochrany na modelovém projektu komplexní pozemkové úpravy
VALENTA, David
This thesis addresses the issue of erosion protection in a model comprehensive land consolidation. At the beginning of the thesis the theoretical part is described, which deals with the land consolidation itself, soil erosion as such and last but not least with pro-erosion measures. In the next part of this thesis the area of interest Svojšice u Sušice is described with all the conditions that concern the area. Furthermore, the long-term average soil loss on individual soil blocks is calculated using the universal equation according to Wischmeier and Smith. In the last part of the thesis, anti-erosion measures are proposed, namely organizational and agrotechnical.

Zvýšení udržitelnosti hospodaření v zájmovém území a navržení environmentálně šetrných opatření
BAŠTÝŘOVÁ, Klára
From a theoretical point of view, the bachelor's thesis analyzes the threat of soil erosion, the possibilities of monitoring and protection against erosion, and the motivation of farmers to protect the soil fund in the Czech Republic through the strategies of subsidy programs. Furthermore, from the point of view of practical application, the establishment of new stands of non-production areas and protective belts around water was proposed in the selected erosion-threatened area. As part of the LPIS, an anti-erosion measure was also proposed in the form of a linear biocorridor, the purpose of which, in addition to protecting the soil from soil erosion, is to expand and support local biodiversity.

Možnosti revitalizace vodních toků v zemědělské krajině
Barsová, Karolína
This thesis solves the revitalization of water courses in the agricultural landscape. The scope was to create a concept for the design of revitalization of watercourses in the model area and develop the proposed details at the level of a feasibility study. Prior to the start of the design, the primary, secondary, and tertiary landscape structure was prepared for the model area. Furthermore, the values and problems of the area were evaluated. All the mentioned items were based on field surveys, which began in the autumn of 2018. Based on the information obtained from the literature research, the field survey and analysis of the area, the concept of revitalization of watercourses was created. The concept consists in a comprehensive design of the entire selected area and works with streamlines, riparian vegetation, the immediate vicinity of watercourses and agricultural land.

Uplatnění meziplodin jako stabilizujícího prvku v protierozní ochraně
MORŤANIK, Michal
The aim of the diploma thesis is, in the first part, the processing of literary research on the topic of erosion, types of erosion, anti-erosion measures, sustainable development, ecological stability of the landscape and the so-called intermediate crops. In the second part of the work is mapped, using the Wischmeier - Smith equation, the impact of the area of interest of the Lohenice cadastre, the village Koberovice water erosion and the influence of individual sowing procedures on the amount of washed soil.

Modeling the impact of the potential anti-erosion measures in the selected area
KOKEJL, Karel
This diploma thesis deals with the topic of water erosion. Specifically, it is a matter of mitigating this process by applying an suitable anti-erosion measure. One of the goals of this work is that a suitable system of anti-erosion measures with a focus on technical anti-erosion measures is proposed for the selected area. Other technical aspects of implementation into the existing digital elevation model and verification of its functionality using the USLE equation in GIS (in this case in the ArcMap program) and modeling of povrchového runoff. In the theoretical parts of the work, the reader is acquainted with the basics of water erosion, detection of water erosion and anti-erosion hazards. Then it is introduced the introduction of the area of interest and the methodological procedure of the work, which is focused mainly on the calculation of erosion and dimensioning of anti-erosion measures.
