Founding in region of Velké Bílovice
Moravčík, Martin ; Masopust, Jan (referee) ; Brdečková, Helena (advisor)
Bachelor's thesis got two parts. In teoretical part I examene geology and geomorfology of region Velké Bílovice. Half of practical part analyse laboratory samples that are taken from Velké Bílovice. I tested samples for physical and index properties and mechanical properties. Second half of practical part is design and assessment of gravity wall by EC 1997. Earth pressures are calculated by ČSN 73 0037. Geological conditions for gravity wall are calcareous clays from examined properties and loess by [5]. Assessment was controled with computer program GEO5.

Mineral composition of agricultural soils developed on loess
Žigová, Anna ; Šťastný, Martin
The study is focused on the comparison of mineral composition of different soil types formed on loess. The soil types were classified according to the World reference base for soil resources. Samples were collected from individual soil horizons. Basic soil properties such as the particle-size distribution, pH values, CaCO3 contents, base saturation, cation exchange capacity, soil organic carbon and nitrogen were analysed using routine pedological methods. Mineral composition was evaluated on the basis of XRD analyses of the fraction < 0.001 mm. Semiquantitative mineral composition was calculated from the areas of basal peaks. The studied soils were found to be dominated by quartz, kaolinite and illite. Semiquantitative analyses of mineral composition of the Greyic Phaeozem, Haplic Chernozem and Haplic Luvisol revealed differences in the association and proportion of individual minerals.
