Flood control measures in the Březnice Catchment
Zárubová, Kamila ; Menšík, Pavel (referee) ; Starý, Miloš (advisor)
This bachelor’s thesis deals with the flood control measures in the basin Březnice. This mainly concerns the assessment of flow rates. The work is divided into two parts: A description basin and data processing in programs ArcGIS and Hydrog. Description of the basin is the description of geographic factors, personal acquaintance with the river, and residents of surrounding villages bordering the stream. Subsequently the river will be process and scheme in program ArcGIS - the catchment area will be divided into partial hanging areas with which it will be worked next. The outputs obtained in this step are used for data processing in the Hydrog program. The intensity of rainfall and the N-year flows will be also calculated . In the end flow rates obtained from the program Hydrog will be compared with the real flow.

Anti erosion protection solution on the basins' borderline in various landscaping projects
HIRŠOVÁ, Martina
The aim of this master thesis is analysis of the problems of anti erosion precaution on the interface basin. The part of this work is literature contains where are described erosion phenomenons and calculation and anti erosion precaution of soil against water erosion. Erosion is calculated by using the universal equation Wischmeier Smith Universal Soil Loss Equation (USLE). Soil loss is solved within the basin catchment, not within administrative boundaries. For this master thesis was chosen cadastral areas Pohorovice, Kloub and Lidmovice. The resulting values are compared with values of a land adjustment project. To reduce erosion loss and protection of agricultural land resources are proposed anti erosion precaution.

Revitalization study for small agricultural-forest catchment
ČASTA, Jiří
Revitalization generally are activities leading to the recovery of ecosystems in the landscape and their stabilization. In this thesis are proposed changes for revitalization of small agro-forestry basin stream called Branná significantly disrupted trough conditions, the banks and a river basin, including throughput migration of aquatic animals.

Anti erosion protection solution on the basins' borderline in various landscaping projects.
MURČO, Tomáš
The graduation thesis analyzes water erosion issue, especially by calculating average earth annual loss using the Wischmeier Smith universal equation. Primary task was to assess and evaluate erosion phenomenon on the model basins' borderlines and review the hydrological and administrative teritorial units overlay from the perspective of rainfall runoff. Secondary task was to explore the possibility and suitability of increasing the rainfall erosion efficiency factor by doubling.

Erosion control solutions on the boundary river basins in different projects land adjustment
HAKL, Filip
Erosion is a natural life process. But man its activities and accelerating erosion phenomena that threatens one of the most valuable components of the environment - soil, which is difficult to make up for hundreds and thousands of years. The Czech Republic is threatened by water erosion over the third and wind erosion, about one-tenth of the local soil. When we add to the volume of soil that are occupied by new buildings, it turns out that the soil relatively quickly disappearing. This work deals with the calculation and solution of water erosion in the village Protivec, using the universal equation USLE, the modified equation MUSLE and CN curves method. The resulting values are compared with the values of a land adjustment project, landscaping and erosion control measures are proposed.

Evaluation of flood flows in the basin Jenín
LEHOVCOVÁ, Lucie
The aim of this thesis is to evaluate flood flows in the basin Jenín stream. Part of this work is the description of the territory that I prepare from the perspective of the geomorphological, geological, pedological, hydrological, agro-natural, climatic and biotic. For flood flows, I used data for the hydrological year 2009 that I acquired from Thomson weir, where meters are installed. In the first part of this thesis, I conducted field research the functionality of the drainage group. The result is data that recorded performance shafts. In the next section I dealt with the evaluation of quantitative indicators of precipitation, precipitation operation in relation to catchment flows on the cap and providing a critical period in terms of the spring thaw.

Land adjustment evaluation in light of water protection in Southern Bohemia.
FRITSCHOVÁ, Hana
The aim of the thesis is to evaluate effects of natural and human activity on water quality of Budsky stream basin, futher assessing current water protection and proposing improvements in the form of differential protection zones. The basin is located on Besednice, Soběnov and Malče cadastral areas and extands to second grade of a water supply protection zone of Rimov reservoir. During terrain reconnaissance of the area were all the factors that could contribute to impaired quality of water in the basin taken into the account; from point source pollution to signs of erosion on the slopes of the basin. Futhermore the link between agricultural pollution, agricultural land erosion, land consolidation and protection of water was explained. Also pedological, hydrological and climate researches were conducted. The result is a redefined design of the water protection zones in question.
