Draft measures against floods in the basin of a small watercourse Mlýnka
Řeháková, Adéla ; Jaroš,, Lubomí (referee) ; Starý, Miloš (advisor)
This thesis is concerned with protection against flooding in the basin of a small watercourse Mlýnka. The aim is to get information about runoff in the watershed and the proposal dry reservoir as flood measure. The first part of thesis deals with the survey watershed, getting materials, schematisation watershed, constructing rainfall-runoff process. In the second part is designed dry reservoir. Schematisation has been made using ArcGIS, rainfall-runoff process was done in software HYDROG and drawings have been processed by AutoCAD.

Realtime Weather in a Landscape Visualisation
Vlček, Adam ; Jošth, Radovan (referee) ; Seeman, Michal (advisor)
Thanks to the increasing computation power the complexity and dynamism of virtual reality is continuously improving. This work aims to examine influences of weather in a landscape and the means to simulate and dynamically visualize them in real time on the current personal computer hardware. The main goal is to find quick well looking approximations rather than a complex physically correct simulation. The work covers using modern programmable GPU not only for visualization but also as a powerful simulation instrument. The main topic is water movement in the terrain and its effects on it like erosion, snow melting and moisture impact on vegetation. This requires dynamic terrain texturing and algorithms supporting fast geometry and normals updates.

Flood control measures in the Nectava River basin
Boháč, Ondřej ; Menšík, Pavel (referee) ; Starý, Miloš (advisor)
This bachelor’s thesis deals with the flood control in the basin Nectavy. The aim is to assess the need enhance flood control in the basin. The work is divided into two parts, the first part deals with own description of the basin and the second part with data processing in programs ArcGIS and Hydrog. The description of the basin consists of a personal acquaintance with the basin and its surroundings, interview with residents of communities located along the river and description of geographic factors in the basin. After obtaining all necessary informations will be basin schemed in the program ArcGIS where it will be divided into smaller sub-basins which will require for further work. The output from the previous step is used for processing in the program Hydrog, to work in this program is also needed to calculate the replacement intensity of rains. Simulation in the program Hydrog are obtained critical period of rains and set N-year flows. In the end the obtained values of peak flows are compared with the actual flows and identifying critical points are assessed for possible flow and flood.

Realistic Model of the Sky
Kussior, Zdeněk ; Bílek, Václav (referee) ; Drahanský, Martin (advisor)
The paper describes a theoretical base and realization of realistic volumetric clouds visualization in an environment of real-time simulator. The first part is concerned with a meteorological background of this problem. I show international classification of ten basic cloud types including a short description and cases of occurence. The following part is concerned with an interaction between cloudiness and simulation core, which is based on the fact, that each cloud acts as a mechanical or an electromagnetic obstacle. This should be considered on some way in simulation. The next part describes technologies and practical implementations of visualization and evaluates their characteristics. Finally, the last chapter describes my implementation and tries to outline project advancement.

Atmospheric Phenomena
Radouš, Jakub ; Milet, Tomáš (referee) ; Kobrtek, Jozef (advisor)
This bachelor's thesis deals with a visualisation issue of several atmospheric phenomena by means of the OpenGL library. The work contains theoretical bases for rain, snowfall, lightning, fog, wind, tornado and rainbow, which are further converted to the form of algorithms. The outcome is an application with graphical user interface that is able to display seven natural phenomena set in a landscape.

Measurement of the rain rate instantaneous value using acoustic method
Kresta, Daniel ; Poliak, Juraj (referee) ; Wilfert, Otakar (advisor)
This thesis deals with implementation of the rainfall rate measurement using an acoustic method. It is divided into four parts. In the first part of the thesis a necessary theoretical knowledge is analysed. The second part contains a design of a workplace used for the measurement. The third part presents and analyses important experimental recordings acquired in the workplace. Then all measured values are processed and applied in the measuring program. The last part summarizes results of the thesis, advantages and disadvantages of using the acoustic rainfall rate meter.

Flood Control Measures Design in the Březnice Creek Basin
Zárubová, Kamila ; Menšík, Pavel (referee) ; Starý, Miloš (advisor)
This thesis deals with the flood control. In particular, the design of a set of small water reservoirs with retention effect (polders) and their effect on flood flows. The work is divided into two parts, the first part refers to the bachelor thesis. In this thesis is description of the catchment, rainfall-runoff process and the evaluation of the ratio. That was got the necessary information for the design of polders. This is an abbreviated repetition of the contents of the thesis, which is a continuation of this work. The second part deals with the specific design of two reservoirs, including hydro calculations and drawings. For this work were used ArcGIS - ArcMap, Hydrog and to create drawings AutoCAD 2010.

Rain Prediction Using Meteo-Radar
Gerych, Petr ; Hradiš, Michal (referee) ; Szőke, Igor (advisor)
This paper deal with the rain prediction in the short time interval. The static pictures from meteo-radar serves as input data. The principle of meteo-radar is explained. The possible methods of the object detection and registration, motion interpolation and extrapolation is described. The flood fill algorithm and Lagrange extrapolation is applied to rain prediction. Application is written in C++ language under OS Linux. The example of the software application results is included.

Atmospheric Efects in WebGL
Brydl, Jaroslav ; Lysek, Tomáš (referee) ; Starka, Tomáš (advisor)
This thesis deals with the simulation and rendering of atmospheric effects in WebGL using Three.js application interface. The principles of functioning and implementation of the effects of altering day and night, clouds, snow, rain and shadows are described. Effects are mostly implemented with GLSL shaders that allow easy use across different platforms.

Compensation of Temperature Instability of the Received Signal Level of Microwave Links
Repa, Pavol ; Musil, Petr (referee) ; Bubniak, Milan (advisor)
This thesis deals with the field of microwave links. Specifically, it is concerned with compensating for the temperature instability of the received signal level of microwave links. This problem is solved according to the proposed algorithm, which can be used to suppress the temperature waveforms, and thus achieve better results in the calculation of collisions in the Telcorain software application. A compensation algorithm has been developed to compensate for microwave links with strong temperature dependence. By~compensating for these non-compliant microwave links, it was possible to reuse them in the calculation of the average rainfall intensity, and hence they were retained in~the~generation of the 2D rainfall maps. The compensation algorithm is implemented in the~Telcorain application, where the individual results of the precipitation calculation can be verified. Throughout the thesis, microwave joints from two manufacturers, each with a~different technology used, were analysed. Their comparison with each other is~the~focus of this thesis, in which the individual differences between these microwave links are published.
