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.

Slope stability calculations for small dams
Hajda, Jindřich ; Hodák,, Jiří (referee) ; Říha, Jaromír (advisor)
There are approximately 20 000 small dams in the Czech Republic. This number entails many ponds or small flood attenuation reservoirs, which provide protection against floods. We do not know much about the structure and material properties of these earth dikes. Concerning the small dam stability the current technical standard ČSN 75 2410 focuses foremost on the angle of both the upstream and downstream slopes in case of different materials, and the method of the stability assessment in case of a dam height being 6m or more. Most of these earth dikes are still standing in spite not being built according to any technical standards. They do not follow any standards mostly because they were built before the modern technical standards were published. This diploma thesis focuses on assigning the degree of a reserve in the safety factor for studies of 5 homogeneous earth dikes and 3 inhomogeneous earth dikes. The calculation was done using the Plaxis 2D software using to the shear strength reduction method. The Calculation of the safety degree is made for 4 typical load cases.

A study of erosion control system using biotechnical conservation measures
Moravec, Jiří ; Sobotková, Veronika (referee) ; Dumbrovský, Miroslav (advisor)
The objective of the bachelor thesis was the study of soil erosion control with application of system of semi-natural measures in chosen small catchment. Digital elevation model was generated and average soil loss was determined by ArcGis tools at each erosion parcel . Design of erosion control at chosen erosion risked locality was create in Microstation software and InRoads utilities. As a type of enviromental erossion control mesures was chosen a system of a earthfill dams with the sedimentation area in combination with grassing. The thesis efforts to point the differences between the possible optimal solution and a compromise solution which respects the requirements of agricultural entities. The solution respects the trend of water retention in landscape and use of low cost measures.

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.

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.

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.

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.
