Flood-plain Analylis of the Karolinka Dam
Píšek, Petr ; Vizina, Štěpán (advisor) ; Vokoun, Martin (referee)
The thesis analyzes flood consequences caused by failure of a damaged barrier or a particular component of water impoundment Karolinka. In the first part of the thesis there is described the history of water impoundments construction, both in the world and in The Czech Republic. The failure rate is described, followed by description of damage caused by flood. Finally, the ways of software modeling of flood wave transition are described, whereas special attention is given to program HEC-RAS. The data preprocessing and preparation were realized by ArcGIS software while HEC-RAS program was used for modeling. The specification of the floodplain of dam failure was the outcome of the modeling. The two inputs of data were used for comparison of results -- altimetry grid 10x10 m ZABAGED and Digital Model of relief of CZ of 4th generation (DMR 4G) acquired by aerial Laser Scanning.
The analysis of the effectiveness of respirators in relation to the nature of the work activity using the Dust TRAK 8530 monitor.
PÍŠEK, Petr
This thesis deals with the analysis of the effectiveness of respirators in relation to the nature of the work activity using the Dust TRAK 8530 monitor. First are presented what dust actually is and the splitting up of individual types of dust particles. Further this work concerns legislative decrees and applicable laws relating to the protection of air quality and health in work environments. The paper also describes protection comprised of respirators and their distribution. Part of this work are the individual measurements from agricultural operations and construction from the demolition of buildings. Based on the measured values, the conclusions are drawn, according to the applicable legal provisions of the Czech Republic.
