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.

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.

Extreme hydrological events in the context of urban planning
Klimeš, Zdeněk ; Dráb, Aleš (referee) ; Duchan, David (advisor)
The purpose of the bachelor thesis was to describe known extreme hydrological events and potential attitudes to minimalize their negative impacts. The thesis was written as literature recherche from different points of view, not only from a one-sided technical or ecological point. It proceeds systematically from describing the historical evolution of the subject matter through the presentation of global ecological problems, outlining the legislative background and the findings from specialised literature, to the examples of current trends. In view of the fact that the issue is so broad, the thesis treats only certain parts in detail. The subject of interest is the demonstration of separate measures against floods and droughts and the effects of their synergy concerning the minimalization of the repercussions of extreme hydrological events.
