Household Energy and Water use in Hawassa, Ethiopia
Legamo, Tarekegn Mamo ; Ščasný, Milan (advisor) ; Havránková, Zuzana (referee) ; Muchapondwa, Edwin (referee)
One of the consequences of increasing demand for water and energy sources is the depletion of natural resource bases while sustainable use of natural resources can substantially contribute to climate change and unwise use of these resources result in air and water pollution, as well as land degradation. This dissertation thesis examines "Household Energy and Water use in Hawassa". The main goal of the thesis is to answer research questions related to the patterns of household water use and energy source choice in the face of growing economy, socio- demographic dynamics and climate change factors-particularly in the context of local environment. As energy and water are the two important environmental goods, the pattern of their use has an impact on local environment, where the analysis of demand for energy source choice and water use has a significant impact, as households are a unit of analysis. A key approach we followed in this thesis is analysing of household survey data based on stratification of socio-economic and demographic variances, geographic location (urban vs peri-urban), and environmental factors. The main energy related data were generated from household survey to analyse the energy source choice based on the three main energy sources; electricity, charcoal and fuelwood along with...

Modeling of water quality in the water supply network
Dukát, Petr ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
This thesis looks at water quality modelling in the water network, focusing on water age. The initial part of the work identifies the factors that lead to an increase in water age in water supply networks. The theoretical part of the work presents the mathematical relationships and logistical steps that software tools apply to simulate water quality indicators in a water supply network. In the practical part of the work, a hydraulic model of a water distribution system with a total length of 302,1 km was constructed. Measurement campaign was carried out to calibrate and verify created hydraulic model. Using this hydraulic model, water age for existing and possible scenarios was simulated. The results of the work have revealed parts of the water supply network containing high water age and are intended to encourage the progressive water distribution systems management philosophy.

Analysis of Water Consumption in Brno
Růžička, Jaroslav ; Kučera, Tomáš (referee) ; Tuhovčák, Ladislav (advisor)
Water consumption is the amount of water removed by the consumer from water disstribution network. During the transportation inside water disstribution network occur losses. Assesing these losses is one of the main responsibillities of the water supplier. We can show the amount of water lost by using several different methods. Values used to describe the amount of water lost can be often replaced by percentual ratio of water produced to water lossed.

Analysis of water age in the water supply network of a selected area
Pellarová, Tereza ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
The bachelor thesis deals with the issue of water age in drinking water distribution system. The theoretical part discusses the factors influencing the age of water and the quality of delivered water, and also the way in which the age influences the quality of water. Furthermore, the methods of age determination are mentioned, as well as indicators of high age. The consumption of mains water and water prices in Europe are also discussed. The practical part of the thesis focuses on the analysis of the age of water in the water supply system. The data needed for the analysis was obtained by means of the EPANET 2.2 tool, in which simulations were performed for periods with different water consumption, including the annual average, summer (July, August) and winter (January, February). After the simulation, the data were entered into MS Excel and then statistically processed and evaluated. The aim of the practical part was to find the correlations of the factors acting in the network. The age/velocity and age/flow rate were examined in the water main sections. The relations between age/consumption from the nodes and age/pressure were examined in the nodes of the network. All data were monitored within the constant age intervals occurring in the municipality´s shared water supply system.

Optimisation of pressure condition in water supply systems
Sucháček, Tomáš ; Svoboda,, Miroslav (referee) ; Pollert, Jaroslav (referee) ; Tuhovčák, Ladislav (advisor)
This thesis is focused on the optimization of pressure conditions in the water supply network. There is a deep theoretical and critical search of the state of the art and there are fields where there is an insufficient field of knowledge, the so-called "knowledge gap". Experiments are proposed here to determine the dependence of water consumption on pressure conditions. There is a description of experiments and way how it was carried out, which were carried out on the water connection, in the pressure zone and in the laboratory on the hydraulic loop. There is proposed a methodology of experimental determination of the mathematical dependence of water consumption on pressure so that it can be used for optimization problems, where consumption is considered as an optimization criterion. The results of individual experiments are evaluated and a critical discussion of the achieved results is carried out. Finally, the achieved results are compared with the values found in a deep literature search.

Vegetariánství a jeho agroekologické souvislosti
Lattenbergová, Michaela
This thesis aims to point out the connections between meat, vegetarian, vegan diet and the environment. The history of vegetarianism and the relationship and the anchoring in individual religions are analyzed in literary research. The differences between vegetarianism and veganism at present, the vegetarin motivation and above all, the impact of meat consumption on environment are analyzed next. As the methodology is used two kinds of field surveys and SWOT analysis. In practical part was for comparison selected three sample menus and their impact on the environment. The results of all the methods used confirm, vegetarian diet is not necessarily more environmentally friendly than a meat-based diet, depending on consumer preferences of individuals. However vegan diet is prooved as more environmental friendly diet.

Nakládání s pitnou, dešťovou i odpadní vodou ve vybraných domácnostech
Absolín, Pavel
This bachelor thesis focuses on an evaluation of the usage of drinking, sewage and rainwater in Czech households. The first part consists of literary review. In addition to providing detailed information on drinking, sewage, and rainwater, this section also addresses ways of using sewage water and rainwater within the household. Water management in sixteen selected Czech households is examined in the practical part. The data used were obtained in the form of a questionnaire. The data were measured in the period between 1.11.2017 and 1.11.2018. The research shows that the average consumption of the drinking water in selected households is 88,2 l per person per day. Family houses show higher consumption of drinking water per person than the apartments. The water consumption is declining as the average age of household members is increasing. The practical part also consists of suggestions of measures which lead to savings.
