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 earth-fill dam of the Karolinka waterworks
Svoboda, Vojtěch ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
The bachelor‘s thesis is focused on selected parameters monitoring of the earth dam of hydraulic structure Karolinka. The first outflow areas on the Karolinka dam air face were already observed and the seepages were measured after the first filling. As a result, in addition to standard monitoring, monitoring of the dam by electrical impedance spectrometry was started in 2011. During the reconstruction of the dam in 2013 was realized the construction of the sealing wall for minimalized of seepages. The selected data were compared before and after reconstruction of the hydraulic structure Karolinka. The bachelor‘s thesis was realized within the sustainability of the international project E!7614 of EUREKA program.

Reliability analysis of embankment dams endangered by filtration deformations
Čejda, Marek ; Baroková,, Dana (referee) ; Fošumpaur, Pavel (referee) ; Říha, Jaromír (advisor)
Subject of the dissertation is a probability analysis on creation of embankment subsoil filtration deformations. Out of the broad topic of filtration deformations, the dissertation is focused at initiation of the process. At this phase, the overlying layers downstream of levee get uplifted, and eventually get breached. The process of downstream subsoil failure probability estimation is formulated using mathematical and statistical modelling. Within the scope of parametrical study the suggested method is applied onto a test environment. Results of the probability estimation are compared with results obtained using Limit state design method. The results of stochastic modelling can be used for improvement of Limit state design method precision.

Analysis of the earth dam monitoring of a small water reservoir
Králíková, Štěpánka ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
The diploma thesis deals with the use of the electrical impedance spectrometry method (EIS) and the devices Z-meter II, Z-meter III and Z-meter VI based on it for the monitoring earth-fill dams of small water reservoirs. The devices were developed in the Laboratory of Water Management Research of the Institute of Water Structures of the Faculty of Civil Engineering of the Brno University of Technology by solving international project of applied research in the EUREKA program. The analysis of monitoring of the dam of the small water reservoir Bezedník III, which is located in the cadastre of the village Kobeřice, was carried out. Monitoring was carried out from 2006 to 2012. One-off control measurements followed by analysis of achieved results were carried out in 2016, 2018 and 2019.

Safety Assesment of the Rouchovany Dam during Floods
Menšík, Kryštof ; Jobánek, Stanislav (referee) ; Jandora, Jan (advisor)
The main goal of the bachelor’s thesis is the safety assessment of the Rouchovany Dam during floods in accordance with ČSN 75 2935. The thesis contains information about hydraulic structure itself and of its segments, hydraulic calculations, set up permissible water level and control maximal water level. The result of the thesis is the evaluation of current condition of body of hydraulic structure and proposing corrective measures.

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.

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.
