Possibilities of stream restoration in urban environment
Zouhar, Radim ; Veselá, Olga (referee) ; Králová, Helena (advisor)
The thesis is focused on the options of stream restoration with its surroundings in a place of nature area „Na Loukách“ in town district „Mokrá Hora“. The thesis also describes current condition and development of the land use of focused area. There is junction of three creeks in the focused area. In part of this area there is not original depth of ground water surface due to adjustment of Rakovec creek. This thesis introduces three options of increasing depth of ground water surface. Evaluation of the current condition of creeks was performed by the HEM method. Hydraulic calculations were made in HEC-RAS program.

HOUSE ON THE FOOTHILL - TOWN HOUSE IN THE HISTORICAL CENTRE

Potential sites lies not only in its location but also the dominant position it holds to their surroundings. Undeveloped plot represents a "node" or "island" ... loosening strictly linear character Bakery. It is a place which brings together three disparate streams - Classical serious at the running part of Mendel Square, dramatically quarreling upper section flowing into the area from Hus class and insignificant Anenská that, if there "just got lost." All "three" street, however, are closely connected with the plot and the transformation of space clearly indicates their transformation. A distinctive feature of the property is its visual exposure of looking from Mendel Square, the plot creates a "picture" to which the pawn closer. This image should be interesting, changing to attract one's attention for more than just one or two seconds. The image should not least communicate - what is happening on the ground, what links are individual objects ... a landmark and should, for use by infantrymen use. It should also not be attractive from a distance - when one zooms in close proximity, should be surprised by the discovery of something new, something that was not noticeable from a distance, it should be attention to detail, or idea that can be seen only at close contact.

Numerical Modelling of Counter Flow in T-Junction
Míčka, Martin ; Šperka, Oldřich (referee) ; Štigler, Jaroslav (advisor)
The main objective of this master thesis is to implement the numerical modelling of the confluence of streams in the Tee-junction using Fluent CFD software. Modelling is carried out for different ratios of flow rates in steady flow. Calculations are evaluated, using a new mathematical model, by curves of loss coefficients. Furthermore, the influence of the selected type of the mesh in geometry on results from numerical modelling of flow is examined. Geometry of the Tee-junction is created in Gambit software. Finally, the results obtained from numerical modelling are confronted with results from an experiment.

Vliv intenzity hospodaření při obnově dubových porostů v oblasti soutoku Dyje a Moravy na diverzitu pavouků (Araneae)
Rychlá Hulejová, Petra
In this thesis, the intensity of management (presence of mechanical soil preparation) of the post-harvest stand and its effect on spider communities was investigated. There were chosen ten locations for the research, which were divided into 5 intensively managed and 5 extensively managed plots. A ground trapping transect was placed in each plot. Sampling were made on the following dates: 18 May 2021, 17 June 2021, 19 July 2021, 19 August 2021, 01 October 2021. A total of 7001 individuals belonging to 16 families and 85 species were captured, of which 12 species were on the Red List of Protected Species in the Czech Republic. Pardosa lugubris was the most abundant species and Trochosa spinipalpis from the Red List species. The most abundant family found during the survey was the representative of the family Linyphiidae. Primarily individuals with a ground hunting strategy were captured in the ground trapping survey. However, a number of net species were also present. The number of species was significantly higher in areas extensively managed without mechanical soil preparation. The conservation value and abundance of rare and endangered species was also significantly higher in plots under extensive management. It was also found that the effect of management did not affect the overall abundance of spiders. Significant factors influencing spider species composition included vegetation cover and the presence of small wood residues covering the soil surface. According to the results, it can be concluded that extensive management has a positive effect on spiders. Therefore, we recommend this type of management as a positive method that could be further used in the restoration of oak forests in the Soutok Forest Reserve, or in other areas with valuable floodplain forests.
