Posouzení erozního ohrožení vybraných svahů na území podniku Smilkov a.s.
FULÍN, Patrik
The aim of the bachelor thesis is to assess the erosion threat of selected slopes in the territory of the Smilkov a.s. company and the subsequent proposal of anti-erosion measures leading to the reduction of the observed erosion and protection of the surrounding landscape. According to the results, erosion control measures were developed, consisting in the division of the land into parts. Furthermore, an anti-erosion seeding practice was proposed for each soil block. As a result of the erosion control measures, the long-term soil loss was reduced below the permissible soil loss limit.

Posouzení erozního ohrožení vybraných svahů na území obce Nalžovské Hory
MAREŠ, František
Erosion is a natural phenomena that occurs at different scales in the vast majority of the world. This thesis deals with water erosion in cadastral territory of town Na-lžovské Hory in district Klatovy. In the first part, concept of erosion is described as well as its emergence, causes, effects and protection of the soil by suitable erosion control measures and the specific legislation of the Czech Republic. In the second part of the thesis, selected lands at risk of erosion are assesed according to the information on the LPIS application, followed by using soil erosion calculator to determine appropriate erosion control measures and proper sowing procedures.

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.

The design of erosion control measures in a small basin
Prchlíková, Simona ; Kameníčková, Ivana (referee) ; Doležal, Petr (advisor)
Main goal of this bachelor thesis was the proposal for protection against erosion in selected river basin. Digital model of terrain was created with the help of ArcGis tools. Average yearly erosion wash off was determined by calculation in ArcGis software. The assessment was determined by two factors that influence threat level for particular area. The goal is to highlight the differences between the levels of threat by water erosion after two various rain types. Selected erosion control measures were suggested for the worse option. Chosen appropriate measures were as follows: grassing, erosion control crop rotation and interruption of slope by furrow. Subsequently, new erosion control measures were implemented into the calculation of new state of threatened area. In the final comparison, after implementing erosion control measures, it was a significant and noticeable improvement in conditions. Solution respects trend of water retention in the landscape and use of low-cost measures.

Evaluation of erosion and runoff conditions in context with the agroforestry systems design
Vaňousová, Martina ; Skřivanová, Zuzana (referee) ; Sobotková, Veronika (advisor)
The diploma thesis generally deals with the emergence of water and wind erosion, its conseque-nces and the possibilities of how to prevent or limit erosion, with various anti-erosion measures. More specifically, it focuses on agroforestry systems (ALS), their origin, importance and appro-priate use in the landscape. To investigate the effects of ALS, an agricultural area near the village of Modřec was selected, on which ALS variants in various variations were designed using compu-ter programs. The main quantity investigated and compared was the average long-term soil loss by water erosion under different variants of the ALS design.
