Effects of nitrogen supply and drought on wheat grain quality under the ambient and elevated concentrations of carbon dioxide
Moravcová, Gabriela ; Vránová, Dana (referee) ; Hrstka, Miroslav (advisor)
This diploma thesis deals with effects of nitrogen supply, drought and UV radiation on wheat grain quality under the ambient and elevated concentrations of carbon dioxide. The theoretical part deals with the global climate changes, greenhouse gases and especially with effects of elevated concentrations of carbon dioxide on plants. Also, it is dealt with effects of elevated concentrations of carbon dioxide on the wheat grain quality. In the experimental part nitrogen content by the Kjeldahl method, contents of dry and wet gluten, Zeleny test, falling number and content of starch in the wheat samples were determined. The results of this study confirmed affecting the quality of the wheat grain from the elevated concentrations of CO2, nitrogen fertilization, drought and UV radiation. The most evident was the influence of nitrogen nutrition, fertilization positively affected the quality of grain, there was an increase in content of crude protein, gluten content, value of Zeleny sedimentation test, and falling number. As a result of the increase in protein content was also a decrease in starch content. Due to increased levels of carbon dioxide protein content and gluten, Zeleny sedimentation test values and falling number decreased and conversely starch content increased. The decrease of Zeleny sedimentation test by the influence of elevated CO2 concentration was fully compensated by nitrogen fertilization.

Climatological analysis of the Thaya river basin
Macík, Ondřej ; Kněžínková, Barbora (referee) ; Marton, Daniel (advisor)
The current climate changes and the persistent drought raise questions about the future development of temperatures and precipitation in the Czech Republic. One of the most affected area is south Moravia and the basin of River Dyje located there. The iam of this bachelor's thesis is to predict the future development of climate in the basin of River Dyje, using emission scenarios, a global climate model and an artifical time series Baseline by using a stochastic generator LARS-WG and subsequent analysis of the results. The obtained results will be suitably compared with each other and adjusted to the form for their future use.

Linking technical and natural infrastructure to climate change in cities
Svobodová, Lenka ; Hyánková,, Eva (referee) ; Hyánková, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
The thesis is focused on linking technical and natural infrastructures in cities with respect to climate change. Various means of growing plants are presented by introducing urban farming. In the first, theoretical section, climate change is claimed to be a global threat for human kind which is more and more visible in cities. Many examples of adaptation and mitigation of climate change in cities are displayed. In the second, practical section, one existing technical measure from Brno city is examined – difference between technical and natural infrastructure is demonstrated. Finally, calculation method for environment-friendly crops growing, not only for cities, is introduced.

Design of erosion and flood control measures in the study case area responding to climate change
Mrázek, Vojtěch ; Larišová,, Lucie (referee) ; Sobotková, Veronika (advisor)
The aim of the work is to design anti-erosion and flood protection in the area of interest KÚ Lukavec to the current state and responding to climate change. At the same time, it is necessary to assess the degree of erosion threat to the soil and analyze runoff conditions in critical areas. The introductory part summarizes information about the studied area and methods for calculation. The erosion analysis is processed in the design part and suitable anti-erosion and anti-flood measures will be proposed. DesQ-MaxQ software was used to calculate the runoff conditions, graphical outputs and analysis of erosion conditions were created in the ArcGIS environment.

Water management analysis of reservoir under climate change
Smolík, Lukáš ; Benáčková, Kateřina (referee) ; Marton, Daniel (advisor)
The presented bachelor thesis is focused on the analysis of impacts of climate change on the water reservoir. The work consists of several partial steps. The first step is the calibration of the balance of the hydrological model to the current climatic and hydrological conditions. The next step is the construction of hydrological time series burdened by climate change. That the calibrated model was compiled, it must be used calibrated balance model and climatic data loaded climate change. Selected emission scenario used in the work of the emission scenario RCP4.5 the final step of the work is to analyze the reservoir volume by using the simulation model of the tank and its evaluation in view of possible future climate change. The functionality of the described procedures will be verified for the analysis of impacts of climate change on the reservoir capacity of the reservoir in the defended Hanušovice profile in the Morava river basin.

Water Management Analysis of Reservoir Storage Capacity Due to Climate Change
Šenková, Monika ; Menšík, Pavel (referee) ; Marton, Daniel (advisor)
The aim of this work is a water management solution of the storage volume of the Vlachovice reservoir in the conditions of climate change. Due to the long-term drought and flood period, the Czech Republic decided to build multi-purpose reservoirs. One of them is the multi-purpose water reservoir Vlachovice. The tanks are designed for a certain storage volume, which is calculated from the flow series in a given water profile. Flows on watercourses are conditioned by climatic and geomorphological conditions. Climatic conditions are constantly changing and significantly affect flows. It is difficult to determine the future of water flows. Future flows are generated based on measured values ??and expected climate change using mathematical models. In this work, just these two scenarios of the future of flow series depending on the amount of precipitation and temperature changes are compared.

Extreme hydrological events in the context of urban planning
Klimeš, Zdeněk ; Dráb, Aleš (referee) ; Duchan, David (advisor)
The purpose of the bachelor thesis was to describe known extreme hydrological events and potential attitudes to minimalize their negative impacts. The thesis was written as literature recherche from different points of view, not only from a one-sided technical or ecological point. It proceeds systematically from describing the historical evolution of the subject matter through the presentation of global ecological problems, outlining the legislative background and the findings from specialised literature, to the examples of current trends. In view of the fact that the issue is so broad, the thesis treats only certain parts in detail. The subject of interest is the demonstration of separate measures against floods and droughts and the effects of their synergy concerning the minimalization of the repercussions of extreme hydrological events.
