Analysis of the earth dam monitoring of the water structure Karolinka
Koudelková, Eva ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
This diploma thesis deals with the analysis of the monitoring of the Karolinka water reservoir earth dam. For the reason of seepage detected on the downstream face of the dam, the water reservoir was operated in a limited regime practically from its beginning. One of the most significant interventions aimed at reducing them was the installation of a sealing wall realized in 2013. Since 2011, the earth dam has been pilot-monitored by probes of the electrical impedance spectrometry method. The thesis deals with the processing of the data obtained by this method and with the comparison of the determined electrical conductivity of the dam soil with the data measured on the earth dam (temperature, water level in the reservoir, seepage) before and after installation of the sealing wall.

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.

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.

Flow structure in shaft spillway area of of Labská dam
Šváb, Jiří ; Pařílková, Jana (referee) ; Zachoval, Zbyněk (advisor)
The bachelor thesis is divided into literary research and practical part (own measurement). The content of the literary research is a description of the shaft spillway, the Labská dam and the measuring equipment. The practical part is focused on measurement of the horizontal velocity, flow distribution and water surface elevation on the shaft spillway physical model. The results are horizontal velocity for two levels, water surface elevation and flow distribution.

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.

Verification technology BioSealing by EIS method
Fránková, Hana ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
Diploma thesis is dealing with recognition of Biosealing technology using electrical impedance spektrometry method. BioSealing is an innovative method of soil body reconstruction, which uses stimulation of soil bacterial activity to seal the leakage. The method was developed in the Netherlands and it was used in conditions of the Czech Republic in years 2015 and 2016 on the Hornice water work. This earth dam was monitored by electrical impedance spectrometry by apparatus with device Z-meter IV in this period and the data are processed and assessed in this diploma thesis.

Lateral recirculation zones of flow in approach channel of weir
Korálová, Nikola ; Pařílková, Jana (referee) ; Zachoval, Zbyněk (advisor)
The bachelor’s thesis is divided in to the literary research and practical part. The content of the literary research is the issue of side contracted weirs, where occurs side contracted flow. The sudden change of the channel width and formation of upstream wake have direct influence on value of discharge coefficient. There are described types of the weirs, ways of computing discharge and discharge coefficients which are influenced by contraction. In the practical part of thesis is described measurement of the velocity field of side contracted flow by UVP Monitor, follow up by assessment of boundary of the upstream wake, which is situated in the approach channel in front of the weir.

Monitoring of filtration processes in earth dams
Gardavská, Zuzana ; Bartušek,, Karel (referee) ; Satrapa,, Ladislav (referee) ; Pařílková, Jana (advisor)
This doctoral thesis with the title „Monitoring of filtration processes in earth dams“ represents possibilities of using electrical impedance spectrometry method (EIS) and devices Z- meter II and Z- meter 2A based on it for using a monitoring earth-fill dikes of small water reservoirs. The devices are developed in the Laboratory of Water Management Research Institute of Water Structures Faculty of Civil Engineering Brno University of Technology through international projects E!3838 and E!4981 in EUREKA program. As part of submitted doctoral thesis the monitoring has been conducted at two locations – earth-fill dike of small water reservoir Bezedník III in the cadastral area Kobeřice and earth-fill dike of fish pond Rybník u kostelíka near the village Jevíčko. The general guidance has been compiled based on the knowledge and experience of measurements to monitor earth-fill dike using method EIS. This guide covers the use of method and device Z-meter II from the choice of location and monitored the profile, selection and installation of probes into the dam body, the preparation of measurement location, configuration of the measuring apparatus including a user program Z-scan, through the process of measurement and recommended method of processing data.

Possibilities of detection of water content in porous environments using electrical impedance spectrometry method
Fejfarová, Marie ; Bartušek,, Karel (referee) ; Bednárová,, Emilia (referee) ; Pařílková, Jana (advisor)
This doctoral thesis with the title “Possibilities of Detecting the Water Content in a Porous Medium Using the Method of Electrical Impedance Spectrometry introduces electrical impedance spectrometry (EIS) as an indirect electrical method of measurement and a tested apparatus for application in water management practice and in material engineering. A wide range of porous media in the area of water management have been narrowed within the preparation of this dissertation thesis to available samples of chiefly sandy soils and in material engineering to typical building materials, which are still solid burnt brick and timber. Measurement took place in the Laboratory of Water Management Research of the Department of Water Structures and in the Laboratory of the Department of Building Materials and Components at the Faculty of Civil Engineering of Brno University of Technology, in the Laboratory of Soil Mechanics of the company GEOtest, a.s. and in the Laboratory of the foreign university KU Leuven, KHBO in the City of Oostende, Belgium. The experiments performed required not only the production of special constructions of measuring probes and their connection, but also modifications of stations at which measurement was carried out. It is possible to use this doctoral dissertation thesis as a methodological manual of how to apply the measuring apparatus based on the EIS method in monitoring changes in the water content in selected porous media due to hydrodynamic stress imposed on it.
