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.

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.

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 anomalous area of homogeneous earth dike of small reservoir
Sedláková, Alena ; Maleňák,, Jaroslav (referee) ; Pařílková, Jana (advisor)
This thesis deals with the assessment of changes occurring in the earth dike of small water reservoirs Bezedník III. in the village Kobeřice and the definition of anomalous areas identified by the indirect method of measuring electrical impedance spectrometry (EIS). The study conducted on the basis of data processing from monitoring, which is carried out once a month. The thesis follows the solution of projects E!3838, E!4981 and E!7614 in international EUREKA program.

Determination of active zone of bed load sediment trap
Sodomka, Václav ; Pařílková, Jana (referee) ; Zachoval, Zbyněk (advisor)
The bachelor thesis deals with determination of the active zone of bed load sediment trap in the water reservoir of Nové Heřminovy. A ready-made physical model of the sediment space was used and more accurate measurements of behaviour of the proposed object were performed. Ultrasonic speed field measurement was used for determination of the active zone of the sediment space. The Surface-water Modeling System programme was applied for evaluation. This information can be used for further assessment of bed load sediment trap. The results show that transported bottom sediment is trapped in the space determined for this purpose and there are no unforeseen phenomena. The model behaves within the limits of the initial assumptions. That means it is correctly designed and it will be more likely to serve its purpose.
