Environmental assessment of the Czech Republic based on Water Footprint
Žlábková, Jana ; Hák, Tomáš (advisor) ; Vačkář, David (referee)
This dissertation sets its goal in application of the water footprint indicator, which is a practical and multi-layered indicator of water sources consumption. Of human activities, agriculture presents the most significant demands on water sources consumption. Therefore I have turned my focus to the widely-discussed issue of biofuels production, because the input materials for production of this kind of energy are agricultural crops (in the Czech republic those are: oilseed rape, sugar beet, Indian corn and winter wheat). The calculated results of water footprints of the selected industrial crops (m3 /t) and of water footprints of the heating value units of that crops (m3 /GJ) offer us a concrete notion of energy requirements of water of that chosen industrial crops in the conditions of the Czech republic. Keywords: water footprint indicator, biofuels, oilseed rape, water consumption, biodiesel, bioethanol, evapotranspiration.

Price elasticity of household water demand in Czech Republic
Hortová, Jana ; Krištoufek, Ladislav (advisor) ; Šopov, Boril (referee)
Během posledních desetiletí se v eské republice stále zvyšují ceny vody, což vede k následnému snižování její spotřeby. Tomuto tématu se věnuje velké množství studií, ale dle našich zjištění se žádná z nich nezabývá eskou republikou. Obecně lze říci, že hlavním cílem této práce je nalezení krátkodobé a dlouhodobé cenové elasticity poptávky po vodě v eské republice a následně v Kladně. Při zkoumání poptávky po vodě v Kladně vyšetřujeme cenovou elasticitu v závislosti na odlišném počtu člen· v domácnostech. V obou případech dojdeme k závěru, že poptávka je neelastická v krátkém i dlouhém časovém období. Dále zjistíme, že cenová elasticita roste s klesajícím počtem člen· domácností v obou časových obdobích. Naše výsledky jsou v souladu se závěry ostatních studií.

Smart Metering of Water Supply System at Campus of Faculty of Civil Engineering BUT
Černíková, Eva ; Ručka, Jan (referee) ; Tuhovčák, Ladislav (advisor)
The aim of this thesis is to perform an analysis of possibilities and benefits of installing the Smart Water Metering technology at campus of Faculty of Civil Engineering, Brno University of Technology. The main goal was to provide specific solutions of Smart Metering systems from different companies. One part of this thesis is dedicated to a detailed analysis of a water consumption measurement campaign that took place at the beginning of this academic year using dataloggers. Real-time flow rate and consumed volume was recorded every five minutes. Therefore it was possible to determine water consumption patterns during the day and also tell the minimum, maximum and average flow rate in different parts of the campus. Thanks to these measurements, irregular water consumption during the night was observed. This would not have been easily detected without recording real-time data. This system of recording real-time flow rates with dataloggers is considered to be suitable for the needs of faculty. Thanks to a GSM module, recorded values are sent to an FTP server once a day. From there the data can be downloaded to any kind of analysis software. Installation of Smart Water Metering technology at campus of Faculty of Civil Engineering would be beneficial for both operation of the water supply network and also for purposes of an academic research.

Residential Rainwater Harvesting
Šumichrastová, Mária ; Vendlová, Lucie (referee) ; Wierzbická, Helena (advisor)
The aim of this work is to approach the issue of the use of rainwater in building constructions. This water is widely used for routine activities in the home, which contributes to saving drinking water. At the beginning of my work I focused on what water actually is, and a brief description of each treatment on the basis of their quality. In the first part of about reasons for rainwater management and access to the use of water collection at home and abroad. The second part describes possibilities of application of rainwater in the home. Describes the concept of the need for water, which is essential for the design of the facility. The design of tank is explained in part 3, where I describe the factors affecting the amount of water collected. The following chapters are focusing on individual elements making up the system for the management of rainwater. Chapters are divided according to their function, namely: filter portion, accumulation and a section giving water to the "movement".
