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.

Design of erosion and flood control measures for the selected cadastral area
Svoboda, Jiří ; Uhrová,, Jana (referee) ; Sobotková, Veronika (advisor)
This bachelor thesis is in the introduction focused on the evalutation of the current erosion and runoff conditions in the cadastral area of Zádolí u Vysokého Mýta and in the cadastral area Střihanov. The analysis of current erosion and runoff conditions is carried with the use of programs ArcGIS, USLE2D and DesQ–MaxQ. The following is a design of erosion and flood control measures with the main aim of protecting the village Zádolí–Střihanov. Then the design technical measures are dimensioned for the specified design flows. In conclusion of the thesis is evaluated the efficiency of the design protective measures and the average soil loss and runoff quantities are compared before and after the design of the protective measures.

Design of erosion and flood control measures in the cadastral area of Palkovice
Ujházy, Adriana ; Uhrová,, Jana (referee) ; Sobotková, Veronika (advisor)
This diploma thesis deals with design of soil erosion control measures and flood control measures in the cadastral area of Palkovice. The request for construction came from the village Palkovice. It sits at the foothills of Beskydy with a very sloping terrain. In addition, there are larger soil complexes without any erosion control measures, which leads to degradation and reduction of soil yields. The introduction summarizes desired objectives. Then thesis deals with the description and analysis of the current state of the village and its solution. The solution of technical measures is depicted in the situation and elaborated in more detail. The drawings are enclosed in attachment. The conclusion summarizes the content of the work, achieved goals and benefits.

The design of the measures for flood protection in the small watershed
Hrnčíř, Rudolf ; Ing.Daniel Doubrava (referee) ; Doležal, Petr (advisor)
My thesis is focused on project of water management measure which should intercept torrential water endangering municipality Starovice. Intensity of soil ablation of affected land is evaluated by Wischmeier-Smith method. Based on the result of long-term soil lost and gathered materials and information three options of erosion control are suggested. Thereafter these options are compared on the basis of efficiency and the most suitable and the most effective option is selected. Also parameters of intercepting ditch are recommended and it is projected for capacity of direct water runoff from slopes above the ditch. As part of thesis maps were created using ArcGIS program and sample diagonal incisions of the intercepting ditch were created in AutoCad program.

Využití druhu Terminalia brownii pro zalesňování v jižní Etiopii
Raab, Jakub
This work is primarily focused on determining the growth capacity of Terminalia brownii species during plantations under mechanical erosion control measures in the southern region of Ethiopia. The aim of the work is therefore to determine the growth capacity and its properties in two standard types of erosion control measures and compare them with the growth characteristics of natural regeneration occurring in the study area. To address this issue, a field research was organized in Arba Minch, Ethiopia, where plantations of the investigated species were implemented. The area of interest was divided into test plots, where the number of planted seedlings, the number of growing individuals, and the number of naturally regenerated pieces were counted. The height and stem diameter at a height of 15 cm were measured for each growing individual. The results evaluate the mortality of the species in various erosion control measures and its growth characteristics. The work thus demonstrates the growth capacity and the dependence of height on stem diameter for different forms of erosion control measures.
