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.

Posouzení erozního ohrožení vybraných svahů na území obce Litochovice
BABKA, Václav
Erosion is now a major global problem. In my thesis I focused on its impact on land in the cadastral area of the village of Litochovice in the South Bohemian Region near the district town of Strakonice. The content of the first part of the thesis is an ex planation of the problem of erosion, especially water erosion, its causes and con sequences, as well as some possible erosion control measures that can suppress water erosion or at least mitigate its consequences. However, other types of soil erosion are also mentioned. In the second part of the thesis, I assessed individual plots in terms of erosion risk using the LPIS application and suggested suitable farming methods, erosion con trol measures and seeding practices using the application Protierozní kalkulačka.

Water areas localization in landscape as adaptation measures to eliminate climatic extremes
Mokrejš, Filip ; Moravcová,, Aneta (referee) ; Sobotková, Veronika (advisor)
The subject of the diploma thesis is the analysis of the cadastral area of the municipality of Čejkovice concerning erosion and runoff conditions. ArcMap and USLE2D programs were used to evaluate erosion conditions. The determination of runoff characteristics was preceded by the identification of critical profiles, for which the calculation was subsequently performed in the DesQ-MaxQ program. Based on the evaluation, suitable erosion control measures were proposed, and the post-design condition was evaluated. Finally, the work focuses on small water bodies. Using the available literature, recommendation criteria for the selection of locations for small water bodies were established and a selection of suitable sites in the area of interest was made. The selected sites were developed into details of documentation for planning permission.

Uplatnění meziplodin jako stabilizujícího prvku v protierozní ochraně
PICKA, Patrik
The bachelor's thesis on the topic of the application of intermediate crops as a stabi-lizing element in anti-erosion protection aimed to assess the usability of intermediate crops in sowing procedures in agriculture. Other examined variables included the evaluation of the effect on the increase of water retention in the landscape and the anti-erosion efficiency of the vegetation cover. A locality located in the Tábor dis-trict, in the cadastral area of Želeč u Tábora, was selected for the research plan. The work was divided into several parts for clarity. The first, theoretical part of the work deals with the issue of erosion, its distribution, the principles of protection against water erosion and, last but not least, also deals with intermediate crops, which can be used as a stabilizing element in erosion protection. The second part of the work introduces the selected locality and is supplemented by calculations of land-slide in this area. Soil loss was calculated using the Wichmeier - Smith (1978) equa-tion for the sowing procedure without intercrop and with the intercrop. The results of the sowing procedure with intermediate crops were compared and subsequently evaluated. The results of the work showed that the use of catch crops is very favorable for the soil and should be commonly included in sowing pro-cedures. This is due to their ability to improve the soil and extend the duration of the vegetation cover.
