Monitoring of the spread of pollution on the physical model of the watercourse
Marek, Ondřej ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
On the built physical model of the watercourse, a bachelor's thesis is looking for a suitable substance that would allow simulating and monitoring the pollution transport by the method of electrical impedance spectrometry. Physical model based on the similarity of physical phenomena allowed the application of tracers and measurement of their concentration in selected flow profiles at a defined flow. The measurements were made by measuring apparatus made by the solution of the international project E! 7614 applied research in the EUREKA program as part of its sustainability.

Estimating soil effective grain size by EIS apparatus
Chládová, Zuzana ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
The bachelor thesis is focused on the use of electrical impedance spectrometry and its possible application in the estimation of effective particle size of soil. The grain size curve of each soil sample was obtained by using the sieve analysis and aerometric method after which the effective particle size for each sample was determined. Thereafter the frequency analyzes of samples were performed under laboratory conditions using Z-meter. The results showed that it is possible to infer effective particle size when the frequency analysis is performed for example during field measurement. This research was carried out as part of the project E!7614 of the EUREKA program.

Use of EIS method for determination of sedimentation in stady liquid
Hradilová, Iva ; Vachovec, Roman (referee) ; Špano, Miroslav (advisor)
Determination of interface between sediment and liquid belongs to common tasks in various fields of industry like sewage and/or water treatment. The aim of presented work is verification of suitability of electrical impedance spectrometry (EIS) method for determination of interface between soil and water. The suitability was verified on three samples of soil. The first one was a sand while other two were loam of different grain sizes. Introduction of both the EIS method and Z-meter III instrument used for measurements is presented in this work too. Within conclusions the suitability of the method and provability in determination of water-soil interface are discussed.

Evaluations of the durability EIS probes installed in an earth dams
Koudelková, Eva ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
This thesis deals with the assesment of the durability of electrical impedance spectrometry method (EIS) probes installed in earth dam. The chosen earth dam is called Bezedník III and the main reason for choosing this particular dam was the longest period of monitoring this dam. The measuring was carried out by the Z-meter II device during the years 2006–2012 and Z-meter IV device in the year 2016. The recorded data are processed and assessed in this bachelor’s thesis.

Monitoring of the temperature stratification of water using EIS method
Műnsterová, Zuzana ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
Bachelor thesis examines the possibility of using the measuring apparatus based on the application of the method of electrical impedance spectrometry (EIS) for monitoring the temperature stratification of the water. For measurement are used the devices Z-meter III and Z-meter IV, which were designed in project E!4981 and E!7614 international applied research in program EUREKA. Part of the thesis is also a proposal of the probe. The experiment is carried out in a laboratory conditions, Laboratory of Water Management Research, Faculty of Civil Engineering, Brno University of Technology.

Evaluation of the sanation of the earth-fill dam of the Hornice
Králíková, Štěpánka ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
The bachelor thesis deals with evaluation of monitoring and remediation measures implemented on the earth dam of Hornice water structure. In 2014, tracking was initiated using the EIS method. Monitoring is carried out in the EUREKA Applied Research Program and is linked to Project E! 7614. The research is also focused on a new method of seepage remediation, BioSealing. To the application of which in Czech Republic has the exclusive right the company GEOtest, a.s. The processed data used in this work is measured by Z-meter IV and others data are provided by GEOtest, a.s.

Evaluation of changes in pond dam monitored by EIS Method
Novák, Michael ; Maleňák,, Jaroslav (referee) ; Pařílková, Jana (advisor)
The bachelor's thesis deals with the evaluation of monitoring of earthen dike of fish pond which was built near the municipality Jevíčko. To identify the observed changes, which are related to variable loads earth dike with water, in time and space has been selected indirect electrical method of measuring electrical impedance spectrometry. This method is described in the work and the results of monitoring are published in graphical form and are commented.

Spatial analysis of snow cover using the method of electrical impedance spectrometry
Novák, Michael ; Zeleňáková, Martina (referee) ; Janál, Petr (referee) ; Pařílková, Jana (advisor)
Snow cover is an important climatic, hydrological and biological phenomenon. Especially in the empirical sciences, snow and snow cover monitoring has a long tradition, the importance of which has been reinforced in recent decades by the fact that snow cover (it is controlled by temperature and precipitation) is one of the important indicators of climate change. The dissertation thesis deals with the monitoring of snow cover in the years 2016 to 2019, mainly in the Czech Republic, in the Eagle Mountains. The characteristic properties of the snow cover and their changes, caused by changes in temperature, humidity and air flow rate or by the snow's own weight, are monitored by selected and available classical methods and non-traditional indirect method of electrical impedance spectrometry. The aim of the work was to master the measurement technique by a non-traditional method (design of measuring probes, delimitation of the space between the measuring electrodes, data collection and processing). The method is described in the work, the results of monitoring are published in graphical form and are commented. Another goal was to find a suitable mathematical description of the dependence between the measured electrical quantities and the properties of the snow cover, which can be used to determine the water value of snow and possibly also predict the avalanche danger. The technique of measurement by the indirect method of electrical impedance spectrometry was successfully mastered, including the definition of possible adverse effects affecting the measurement result. It was not possible to obtain a statistically significant set of data on the basis of which it was possible to determine the dependence between individual quantities. Classic manual methods can still be considered the standard for snow diagnostics and snow cover.
