Assessment of empirical formulae for determining hydraulic conductivity
Barenčík, Ladislav ; Zachoval, Zbyněk (referee) ; Říha, Jaromír (advisor)
The main purpose of this diploma thesis is to check up and compare empirical formulae (Hazen, Slichter, Terzaghi, Beyer, Zauerbrej, Krüger, Kozeny, Zunker, Zamarin, USBR, Pavčič) for determining hydraulic conductivity, which are mostly publicated in different and dimensionally inhomogenous forms. The importance of an accurate determination of hydraulic conductivity and the derivation of a general formula for determining hydraulic conductivity are listed in the first part of this diploma thesis. Assessment methodology and empirical formulae in dimensional homogenous form are described in the following part. Evaluating and comparing of empirical formulae is mentioned in the last part. According to the results of this diploma thesis, the best empirical formula for determinig and estimating hydraulic conductivity is Hazen formula. Formula with the widest range of validity is Slichter formula.

Studie návrhu malé vodní nádrže v k.ú. Kunštát
Rotroeklová, Brigita
This bachelor thesis is focused on the study of a small water pond a cadastral area of Kunštát na Moravě. The small pond should support a biodiversity, serves as aesthetical landscape component and primarily withholds water in the landscape. The basis for this study is collecting information about geology, pedology, hydrology, climate, bioty and evaluation of the condition of that locality whose part is Újezdský potok. The work includes even a laboratory analysis of soil. After the evaluation of all ascertained facts, there will be made a design without individual technical details. Also, the varieties of financial supports of the potential project are included.

Comparation of methods of granulometrical analysis of coarse fluvial sediments
Bakešová, Veronika ; Hartvich, Filip (advisor) ; Bernsteinová, Jana (referee)
This bachelor thesis deals with the granulometrical analysis of coarse fluvial sediments. A granulometrical analysis is analytical study for finding the percentual representation of each fraction. Granularity is the basis for classification of clastic sediments. Clastic sediments are sedimentary rocks consisting of the rock fragments transported to the place of sedimentation in the solid state. Coarse clastic sediments are rocks in which predominate particle size greater than 2 mm. The theoretical part of this work contains the physico-geographical characteristic of the studied area and the methods used to research grain size of fluvial materials, especially coarse clastic. The experimental part of this work describes the surface sampling method - the digital photography and image processing in the Digital Sedimetrics Gravelometer software. Both investigated streams have similar granularity. The most of the particles from streams falls into the category of grain size 2 - 10 mm. Flows differ only slightly different distribution of fine- grains and medium-sized gravel.
