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 snow cover using EIS method for possibility of determining of the snow water equivalent
Novák, Michael ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
The master´s thesis deals with snow cover monitoring especially in area Orlické mountains. For identification changes, which are related to variable loads on snow cover of temperature, humidity and gravity, 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.
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.
The issue of water infiltration into the soil monitored by the EIS method
Bartoněk, Dominik ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
The bachelor thesis is focused on the issue of water infiltration into soils and acquaintance with methods and procedures for monitoring the infiltration process in field conditions, including the assessment of the suitability of the method of electrical impedance spectrometry for the monitored issues. Infiltration ability of soil are involved in the formation of the landscape due to its resistance to extreme hydrological situations (floods, drought). Infiltration is process in which at exact time and at the certain rate is water absorbed from the earth´s surface into depth of the soil. Infiltration process is based on locality conditions and influenced by natural influences and by human activities. The measurement was performed at two selected localities of the School Forest Enterprise, which is an organizational part of Mendel University in Brno, in particular, of its Faculty of Forestry and Wood Technology. The conception and realization of measuring of rain water infiltration into soil was performed in permanent forest stands located in the cadastre of the municipalities of Útěchov and Kanice. Both localities differ in the structure of the forest stands (species, age, spatial), and therefore the comparison of measured data was performed. In the case of the electrical impedance spectrometry method and the used measuring apparatus, this is a pilot work leading to the acquisition of knowledge, which factors can have a significant impact on soil infiltration and whether it is appropriate to apply the method and the measuring apparatus in this environment.
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.
Determination of water content in the soil by method EIS
Šandová, Iva ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
This thesis deals with the measurement of water content in soil using electrical impedance spectrometry. The aim is to characterize and determine the conditions of applicability of this method and of measuring apparatus with device Z-meter III for instance for the application of the field measurements of earth dams.
Detection of water infiltration into soils injected by clays using EIS method
Marek, Ondřej ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
The diploma thesis deals with the study of water infiltration into soil samples with various types of clay. The soil matrix was represented by homogeneous sand; clay samples were supplied by LB Minerals, Ltd. Soil analysis with injected clays was focused on sealing ability of examined clays for possible use in construction practice for the construction of sealing objects. Electric impedance spectrometry (EIS) measuring system was used to monitor the infiltration process. The measurement was carried out by a measuring apparatus made by the solution of the international project E! 7614 of applied research in the EUREKA program within its sustainability.
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.

Műnsterová, Zuzana ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
Diploma thesis examines detection of residual moisture of porous media of using the measuring apparatus based on the application of the method of electrical impedance spectrometry (EIS). The devices Z-meter of third and fourth generation, were used for measurement, which were designed in projects international applied research. Experiment was executed in Laboratory of Water Management Research, Faculty of Civil Engineering, Brno University of Technology.
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.
