Storm water management in urban areas.
Vaculík, Tomáš ; Tauš,, Miroslav (referee) ; Hlavínek, Petr (advisor)
The diploma thesis is focused on Storm water management in urban areas. The first task for processing thesis was to arrange meeting with MČ Brno - Bohunice Ing. Antonín Crha, who has provided necessary information about the targeted location the and the reservoir for accumulation of rainwater collected. The practical part of the thesis is to capture the rainwater drainage in the existing rainwater sewerage system using the newly built pumping station and then pumping into the existing, unused reservoir. Accumulated water in the reservoir is planned to be used for the needs of the city, gardeners and other customers. The first part of the diploma thesis describes the management of refined water in the Czech Republic, Denmark and Germany. The first part also provides description of measures and technologies for the management of rainwater. Finally, there is description of the pumping station and borehole objects and the program for calculating the rainfall from the urbanized area. In the practical part of the diploma thesis the selected variants are described, rewarded and evaluated. The diploma thesis deals with two variants, that are guided along the same route, with the difference of the construction of the drilled well in the second variant. Both variants are handled by pumping. The option of the gravity inflow was rejected because of the large countersink of rainwater sewerage.

Změny kvality vody v toku vlivem přítoku odpadů z koňské farmy
Khainová, Barbora
The bachelor thesis focuses on monitoring changes in the quality of the Všeminka stream due to the impact of waste inflow from the Všemina Horse Ranch. A total of six sampling sites were identified and located along the length of the stream so that the first location was above the ranch and the last was below the Všemina reservoir. Sampling was conducted four times over a thirteen-month period during the growing season. During the sampling events, pH, dissolved oxygen concentration, conductivity, water temperature, and, for the reservoir, water transparency was determined on site. The samples were immediately taken for evaluation to the laboratory of the Department of Fisheries and Hydrobiology at Mendel University in Brno. Physico-chemical parameters such as total nitrogen, ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, total phosphorus, orthophosphates, total iron, chemical oxygen demand by dichromate, biochemical oxygen demand-five-day, acid neutralization capacity, calcium and chloride were selected for subsequent analysis. The objective was to determine if the ranch has an effect on water quality in the stream or the Všemina Reservoir. The resulting values from the laboratory analysis were evaluated according to the standard CSN 75 7221 used to classify the quality of surface waters as well as according to Government Regulation 401/2015, whether the quality of the water meets the requirements for general water use, for salmon and carp waters. Furthermore, it was compared with similar research works on the given topic of the influence of horse breeding on water quality.

Návrh nádrže pro dřevozpracující podnik
Kobolková, Kristýna
The diploma thesis focuses on the ways of water use in a wood processing company, with special attention paid to a specific method of wood storage that cannot be processed immediately – it is called wet storage, where wood is preserved with water. According to the technical standards, a water reservoir is designed to catch rainfall from industrial sites. The water will be used for spraying logs at the wet storage of company KATR s.r.o. 2 options have been developed. Option A is for an average rainfall (750 mm/year), where it is necessary to build a reservoir with a volume of at least 2600 m3 and a depth of 3 m. It must be supplemented by a absorption field with a volume of 800 m3 and an area of 2100 m2. Option B is for below-average rainfall (490 mm/year), where the design volume of the reservoir is 5300 m3 with a depth of 4 m. The absorption field must have a volume of 909 m3 and an area of 2400 m2. The diameter of the PVC intake pipes was set at DN 300, the concrete pipe at DN 400. For the irrigation system itself, a pump with a flow rate of 5 l/s, a pipe of DN 80 and 7 circular nozzles with a range of at least 18 m were chosen. Excess water will be drained through 0,5 m wide concrete gutters through a lapol back into the reservoir. The design was valued at 4.5 million. funding can be drawn from the grant programme (e. g. Operational Programme Environment)

The use of otoliths for growth and population dynamics studies of Percidae and Cyprinidae in Most water reservoir
Tůmová, Eliška ; Frouzová, Jaroslava (advisor) ; Pivnička, Karel (referee)
This Master thesis compares growth of Percidae and Cyprinidae in flooded mining pit Most with water reservoir Vír, which is stable, fifty years old. Fish were cought using toils by workers from Hydrobiology institute, Academy of Sciences, Czech Republic, which are exploring fish stock. Otoliths, scales, and operculas from both families, Cyrinidae and Percidae, were removed from fish for age determination and growth back-calculation in individual years. Due to surplus of nutrients and food in flooding mining pit is assumed a huge growth difference in the first two years of life. The aim of this thesis is not only to describe the difference in the expected growth of individual species, but also to estimate its causes. At the same time will be in a very contrasting conditions compared different methods of age determination. Key words: otolith, fish age, fish population, fish growth, water reservoir, flooded mining pit, growth back-calculations
