Numerical analysis of stability of retaining structure in cohesive soils
Fejfarová, Aneta ; Račanský, Václav (referee) ; Chalmovský, Juraj (advisor)
The bachelor thesis deals with numerical modeling of excavation using finite element method in the Plaxis 2D software. Triple-anchored retaining structure is founded in a less permeable cohesive soils. There are described loss of stability, types of the calculation and material model (Hardenig soil model used in the mathematical model) in the theoretical section of this bachelor thesis. Mathematical model of the excavation was described in the practical section of this thesis, specifically first limit state. Part of the thesis is an evaluation of the degree of stability over time, pore pressures and critical shear surfaces.

Design of river stabilization structures at the Bečva river in OSek
Lokajová, Hana ; ing. Zedníček (referee) ; Julínek, Tomáš (advisor)
This bachelor thesis is dedicated to the solution of channel recessing in Osek nad Bečvou. One part deals with the evaluation of historical perspective of the area of interest. In the next part of this thesis the transport of sediments is described. The following part contains of an evaluation of current state of the selected part of the river Bečva and deals with a regulation of the river. In the end the theoretical suggestion of protective measure is developed.

Proposal of river training of a small watercourse in the basin of the Morava
Mlčochová, Zuzana ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
The thesis is concerned with an appraisal of capacity of channel and design of suitable measures for environmental protection. Solved segment is located in the channel of Český potok in RK 0,000 – 6,366. The channel is flowing through villages of Čelechovice na Hané, Smržice a Držovice in solved segment. Within own solution the locality was divided into three partial sections, which is enabling clearer description of the proposed measures. Flood measures are proposed in several variants for each partial section. Calculations of flow capacity and water surface for the selected N-year flows were performed by using the program of HEC - RAS 4.1.0. Proposed solutions to flood measures are processed in the drawings documentation.
