Analysis of the economic efficiency of a solar system
Mikl, Antonín ; Pithart, Jan (referee) ; Macháček, Jan (advisor)
The Master’s thesis deals with the processing of solar thermal systems for heating hot water, outdoor swimming pool and heating selected house. Introduces us how we can use the sun for the production of thermal energy through solar collectors. Furthermore, the basic components of the solar system and the types of collectors used. After this summary on the present state be the calculation of the system and fixing the price of the investment. The economic part of the evaluate if this system to invest, eventually appoint a return on investment.

Development Pojects Financing
Šolc, Jan ; Brauner, Roman (referee) ; Heralecký, Tomáš (advisor)
The aim of the diploma thesis is to describe suitable options for financing the development project. The thesis is divided into the theoretical and practical part. The theoretical part focuses on the description of the issues used in this environment, as well as on their forms of financing, in which products and finances procedures are described. The practical part describes the financing f the development project and its subsequent analysis when the financial instruments were used. Trough the analysis of the project, we have obtained results that we an evaluate and then choose a better financial instrument whit financial instrument. At the end of the paper, the benefits and benefits that would come from the design used are outlined.

Risk flood analysis
Krupinec, Jakub ; Dráb,, Aleš (referee) ; Duchan, David (advisor)
The subject of the bachelor thesis "Risk flood analysis" is the processing risk flood analysis on the selected location Thaya flow. Flood Hazard Maps, Flood Danger Maps and Flood Risk Maps for the flow of Q5, Q20 and Q100 are constructed based on available data in accordance with Directive 2007/60/EC. The work was processed in the GIS.

Design precipitation in Czech river basins
Müller, Miloslav ; Kašpar, Marek ; Hulec, Filip
Data on rainfall intensity on the territory of the Czech Republic with a horizontal resolution of 1 km2 and a time step of 10 minutes, obtained by adjusting radar estimates with data from rain gauge stations, were used to derive design areal precipitation in the Czech river basins of 1st to 4th order and in the basins of surface water bodies. When the rainfall accumulation time is doubled, the design precipitation total in individual pixels increases by about 20% on average. The magnitude of the design totals decreases with increasing catchment area, especially for shorter accumulation periods.

Evaluation of the areal extremeness of extreme weather events in Czechia in the period of 1961–2020
Kašpar, Marek ; Müller, Miloslav
Due to the multiplication of impacts of weather extremes when occurring in larger area, we proposed an areal approach of their evaluation. We evaluated six types of extreme weather events, namely, heat waves, cold waves, air temperature drops, windstorms, heavy precipitation, and heavy snowfalls. We employed the original method using the Weather Extremity Index derived from return periods of values of relevant meteorological variables in the affected area. Each event is characterized not only by the areal extremeness quantified with the index but also by the spatial extent and duration. In the studied period, heat and cold\nwaves generally reach higher index values in relation with larger affected area. The increase in the frequency and extremity of heat waves is in contrast with the decrease in the frequency of cold waves and significant heavy snowfalls. The frequency of windstorms is slightly decreasing with the most significant ones concentrated in the cold half-year. Air temperature drops are the most frequent in the warm half-year, nevertheless three of four top events occurred in January. The frequency of heavy precipitation tends to fluctuate. The obtained meteorological database of extreme events may help to estimate the parameters of future ones using climate models.

Analysis of wind gusts over the area of the Czech Republic
Pop, Lukáš
The Ph.D. thesis deals with extreme wind gust analysis over the area of the Czech Republic. The first part of the thesis deals with processing of wind measurements, in particular maximum wind gusts measurements. Analysis of high-frequency wind measurement using 3-D sonic anemometer on the Kopisty station is included. Homogenization of the highest daily wind gusts was performed. Descriptive statistical analysis of measured wind gust values was performed. The following part of the thesis describes statistical theory of extreme values and discusses its applicability to wind gust data. Some theoretical findings were obtained. Numerous numerical experiments were performed focused on evaluation of proposed method. In the last part of the thesis station measurements were processed using the proposed methods and a model of dependence between extreme and mean wind climate was derived. The model was applied to the map of mean wind climate calculated earlier on the Institute of Atmospheric Physics and thus a map of extreme wind climate was obtained. The accuracy of this map was estimated. The map was compared with other maps of extreme wind calculated by other authors earlier.
