Contactless level measurement
Pribula, Wojciech ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
The~thesis begins with an~analysis of~methods of~water level measurement in~high-pressure system. This~systems are placed in~heating plants and power plants and they work with the water whose temperature exceeds 300\,°C and whose pressure is above 10\,MPa. Thesis present method of~differential pressure with the~derivation of~the~correction element and also is~described capacitive method, especially Hydrastep system. This~work prepares theoretical foundation under creating algorithm for level detection using image recognition. Also it considers suitable hardware as~camera and light for illuminating and highlighting the~level. It~includes outline of~captured image editing and detection algorithm. The next part of thesis is dedicated algorithm itself. There are described classes and methods that are used for level detection or for debugging. Also, there are specified necessary modifications of watermark and requirements for watermarks surroundings thats are necessary for proper functioning of the algorithm.

Water Monitoring System for Buildings
Malík, Lukáš ; Franek, Lešek (referee) ; Bradáč, Zdeněk (advisor)
This bachelor thesis designes and realises microcontroller of regulated system for the state monitoring of water pipelines in a building. Demands for the system are listed in introduction. The main part of this work focuses on theory of monitoring systems, additionally it concentrates on design of conception and circuit boards for system. After this the production of electronic circuit boards is performed including the assembly of components onto the board. Controlling of the system is provided by Atmel microcontroller. Significant portion of this work is creation of complex program. At last but not least, functionality of the system is tested and assessed.

Monitoring and regulation of water reservoir
Malý, Michal ; Fedra, Zbyněk (referee) ; Frýza, Tomáš (advisor)
This work is sight on production automatic machine for temperature adjustment and highs water level in reservoir. Automatic machine watch air temperature, water temperature in reservoir and temperatures on solar panel. Further watch water mark in reservoir by the help of rustless probe. By the help of this way adventitious data governs circulatory pump and solenoid valve for suffer waters. Work includes full technical documentation including PCB.

The proposal for the monitoring of groundwater resources
Červenková, Martina ; Kučera, Tomáš (referee) ; Tuhovčák, Ladislav (advisor)
The bachelor thesis follows up the analysis of current state of monitoring groundwater sources – wells, in terms of their quantitative usage and monitoring of water quality. The first part is focused on general information about usage of groundwater in the Czech Republic and in foreign countries too, ways of technical solution of groundwater captation and the description of them. In the second part there is made up the proposed model of monitoring underground water source, the way and frequency of observation of proposed parameters and the resulting demands on technical equipment of collecting objects. Then the implementation of the proposal on two specific areas follows. Finally at the end of this thesis there are described appropriate proposed procuration.

Manipulation with flow rates in water bodies - the possibilities for inhibition of cyanobacterial blooms development
Maršálek, Blahoslav ; Šejnohová, Lenka ; Vinklárková, Darina ; Plotěný, Miroslav ; Jančula, Daniel
If we compare the sediment capping by active barriers to protect the phosphorus release from sediments with other technologies of manipulation with methods of water discharge, it is clear, that by well-considered manipulations with water discharge, it is possible to reach the same (comparable) results with lower costs and with lower ecotoxicological and limnological risks. By the manipulation of water level, it is possible to reduce cyanobacterial bloom development as supplemental or supporting measure, but the effects may differ in different water bodies and thus it must be consulted always with specialists.

Effects of nutrients and water level on \kur{Phalaris arundinacea} growth
KÁPLOVÁ, Miroslava
This thesis is an extension of my Bc. thesis. Based upon previously conducted research in a wet grassland, Mokré Louky, near Třeboň, Czech Republic, a mesocosm experiment was designed for investigating the effect of two nutrient regimes (non fertilized / fertilized) and three flooding regimes (saturated / spring flood / flooded) on Carex acuta and Phalaris arundinacea plants to determine the effect of management type for restoring a more diverse wet meadows system.
