The effect of sampling point on hygienically significant water indicators in natural bathing establishment
Zelinková, Myra ; Benešová, Libuše (advisor) ; Popovský, Jiří (referee)
In this diploma thesis, I deal with the influence of the sampling site on water quality in natural bathing lakes (Hostivar reservoir, Seberak pond and Vyzlovka pond) in this. I have established that hygienically significant kinds of phytoplankton may differ in terms of water quality especially where there are cyanobacteria constituting water bloom. Surface water bloom may be moved by wind to the lee side of the water body (Microcystis sp.). Aphanizomenon flos-aquae water bloom floating in water column can be affected by wind and by water flow (which may be partly affected by wind as well). With the prevailing fibrous Planktothrix agardhii which does not connstitute water bloom the concentration of chlorophyll-a and cyanobacterial cell abundance in individual sampling sites are similar although the concentration of chlorophyll-a a is about 200 g.l-1 . Microcystis sp. and Scenedesmus sp. survive under eutrophic conditions in competition. From the microbiological perspective, water quality can differ within a single sampling site in places at a distance of less than 100 m. Microbial contamination can be caused by bathers, water birds, farm animals and probably by the removing of microorganisms from sand, mud and sediments on the beach or shore. Rain episodes probably increase the abundance of E.coli...

Revitalization of the Small Water Reservoir in the Skalička u Hranic Cadastral Area
Majkus, Martin ; Havlíček, Tomáš (referee) ; Paseka, Stanislav (advisor)
The aim of this paper is to propose a comprehensive revitalization of the side pond in the cadastral area of Skalička. As part of revitalization measures, the removal of mud from the pond, fortification of the banks and other modifications in connection with functional structures are proposed. In order to take water into the pond, a concrete diversion structure in the Hlubocky stream bed is designed, connected with pond via open canal with 2 pools, which will substitute the existing supply pipeline. As part of stabilization of the streambed and to overcome height difference, a boulder chute with stilling basin and related modifications are designed. The introductory part is a summary of knowledge from the issue and it explains important terms, historical context and description of basic principles. The next part describes the current situation and conditions in the surveyed locality. The following is a description of the methods and programs that were used for this work. The design part presents the proposed revitalization measures. An essential part of the work is also the varification of the proposed modification in the streambed, using 3D digital terrain model in Atlas DMT and subsequent 1D flow simulation in HEC-RAS.

3D reconstruction of abandonned ponds using UAV photogrammetry
Stanovský, Tomáš ; Langhammer, Jakub (advisor) ; Blahůt, Jan (referee)
The main focus of the thesis is the reconstruction of 3D models and digital elevation models of five abandoned splash dams in Roklanský brook catchment using UAV photogrammetry methods. The aim of this work is to compare accuracy of the models with available conventional data sources and historical sources. Parallel topic is the research of accuracy of the models created through UAV methods and application of retention potential of small water reservoirs, in headwater areas. The images were taken with a drone-mounted camera. Modelling was done by processing images in software Agisoft PhotoScan through a workflow process, dense point cloud classification and subsequent DEM interpolation. Subsequent delineation of reservoirs retention space, altimetry correction and bathymetric analysis was performed in ArcMap over the interpolated DEM. The results and discussion point to the benefits and limitations of UAV methods, especially to altimetric accuracy of the resulting models relative to conventional DMR5G data and bathymetric characteristics derived from the models. Keywords: UAV; DEM; retention; GIS; model; pond

Home over water
Kosová, Karolína ; Kučera, Radim (referee) ; Struhala, Karel (advisor)
The subject of my bachelor thesis is a project of a new detached house with painting atelier in Martinice u Onšova. The designed house will be partly built partly on plot no. 140/2, the main part of the building is designed above the surface of the large pond (plot no. 145) Detached house for a four-member family has two overground floors. Parking is solved by a detached garage for two cars. Foundations are made up of reinforced concrete large diameter drilled pile and frame structure of strip foundation which supports loadbearing wall. Vertical loadbearing structures are designed of clay blocks. The vertical peripheral structures are provided with an insulation system with ventilated space. Floor-slab is designed of reinforced concrete. A two-layer barrel roof is a dominant of the building. A roof between detached house and atelier is designed as a walkable flat roof.

Složení společenstev larválních stádií motolic (Digenea) u vybraných zástupců plicnatých plžů čeledi Planorbidae
VYHLÍDALOVÁ, Tereza
In the present study the species diversity, seasonal dynamics, composition of larval trematode communities and factors influencing their structure were studied in two species of planorbid gastropods (Gyraulus albus and Segmentina nitida) in typical eutrophic fishponds in South Bohemia, Czech Republic. The study significantly contributed to the present knowledge about the fauna of trematodes in small planorbids, provided evidence for validity of general rules affecting trematode community composition and structure and demonstrated the underestimated role of both snail species as first intermediate hosts for trematodes in the past.

Assessment of design small water reservoir in the village Mutenice in economic terms
Suchánek, Petr ; Doležal, Petr (referee) ; Menšík, Pavel (advisor)
This diploma thesis evaluates a design of a small water reservoir in Mutenice village from an economic point of view. This final work is a follow-up of the bachelor work of the same student, it completes it and improves on previously noticed inaccuracies. There are several aspects elaborated in the theoretical part, such as sellection of material for homogenous dam, safety spilway, accompanying woods in the flooding area of and especialy the evaluation of the commercial advantage of the water reservoir design. There are corrections of the bachelor work in the practical part of this study, based on the comments and lately found facts as well as the economical estimate based on the cost calculation of the construction. Content of the work are also technical drawings illustrating this take on the reservoir design and a detailed bill of material.

Bird territory Jaroslavické rybníky and it's use in natural history class
Sobotková, Petra ; Andreska, Jan (advisor) ; Hanel, Lubomír (referee)
The main theme of my bachelor's thesis is about Bird territory Jaroslavické rybníky, and itś use in natural history class. The work is divided to two parts - theoretical and practical. At the beginning of the theoretical part, I am describing Znojmo district where Jaroslavické rybníky are found. In chapter two I am clarifying ecological concepts, which needs to be known for the following chapter about pond ecosystem and its importance in the nature. The fifth part of my work is about history of fish breeding in Morava, because ponds are often associated with it. Sixth chapter is focused on history of Jaroslavické rybníky, and the following chapter describes bird region Jaroslavické rybníky. Second, pracitical part of the thesis includes suggestions for landscaping practise and work lists associated to them. The lists comprise ecology, zoology and botany. These field exercises are designed for Javorické rybníky and their surroundings. Worksheets are intended primaly for students of second stage of elementary schools, or can be eventually used for repetition of basic knowledge of biology for students of high school. This bachelor thesis is meant to be an inspiration and source of information not only for teachers, but for all who are interested in nature and biology.
