Bridge over a highway
Vaculíková, Klára ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The diploma thesis describes the design of curved, pre-stressed concrete bridge over the highway D1. A variant, that is chosen for detail analysis, is a spine girder construction as a continuous beam with 3 spans. The thesis solves the construction to limit states according to applicable European standards (Eurocodes). There are developed clear and detailed drawings and visualization of the bridge.

Assessment of Ochozsky Brook Status
Vaculíková, Klára ; Tůma, RNDr Antonín (referee) ; Malá, Jitka (advisor)
Bachelor's thesis deals with an evaluation of Ochozský stream in the village Březina in Moravian Karst. There was done a survey of a ground and the stream surroundings. There was also gained information from the Municipal office on technical adjustment of the stream, sewer network, waste water treatment plants and polluters of Ochozský stream. Two measurements of physicochemical parameters and sampling were carried out at six sampling points in autumn 2017 and in spring 2018. Flow rate was measured at three sampling points. Conductivity, pH, temperature, oxidation-reduction potential, concentration of dissolved oxygen and saturation with oxygen were measured in situ. COD, BOD, total phosphorus, ammonia, nitrites, nitrates and Kjeldahl nitrogen were determined in water samples in the laboratory. Organic nitrogen and total nitrogen were calculated. The results were evaluated with a respect of Government Decree No. 401/2015 Coll. There was also provided a hydromorphology assessment of Ochozský stream using methodology Stream Visual Assessment. A land use of the offshore stream strip was mapped.

Pollution entering the Moravian Karst via surface streams
Vaculíková, Klára ; Tůma, RNDr Antonín (referee) ; Malá, Jitka (advisor)
The Diploma Thesis deals with the water pollution entering the Protected Landscape Area Moravian Karst via surface streams. In order to quantify the extent of the pollution surface streams entering the Moravian Karst were selected. A survey of a region of interest was done. Actual volume flow rate, measurements of physicochemical parameters, water samplings, laboratory analyses of samples were done monthly from April to November 2019. Conductivity, pH, temperature, oxidation-reduction potential, concentration of dissolved oxygen, and oxygen saturation were measured in situ. Afterwards, COD, BOD, phosphate, total phosphorus, ammonia, nitrites, nitrates and Kjeldahl nitrogen were determined in the laboratory. Organic nitrogen and total nitrogen were also calculated. The results were evaluated with a respect of Government Decree No. 401/2015 Coll. Material flows were calculated for selected parameters and used as other criterion that evaluate the water pollution of monitoring surface streams. Areas out of the PLA needing an enhanced protection of watercourses were proposed based on quantified pollution. Cooperation with two primary schools in the Moravian Karst supported the research. Pupils and their teachers were trained, and they measured phosphate in surface streams from April to November 2019. The website related to phosphorus in surface water were created and results of phosphate measurement were uploaded there.

Girder bridge over the Lužnice River
Vaculíková, Klára ; Nečas, Radim (referee) ; Panáček, Josef (advisor)
The subject of the Bachelor thesis is the design of the bridge across the river Lužnice. The main topic is the design and calculation of the supporting single-span bridge construction. Three options were developed, the beam constructions and the variant of prestressed prefabricate beams. There was chosen the first option. The structure is post-tensioned. The static model and analysis of the structure has been performed using Scia Engineer 2012.0. Simplified calculations has been done by hand according to Eurocode. The calculation is made without the influence of creep, shrink and time analysis.
