Návrh projektové dokumentace polní cesty konkrétně zohledňující retenci a akumulaci vody v rámci pozemkové úpravy / Draft of the project documentation of field road particulary reflecting water retention and accumulation in the land consolidation

MARKOVÁ, Dana January 2013 (has links)
The goal of this thesis is to draft a project documentation of the new field road reflecting water retention and accumulation within the complex land consolidation. Territory, suitable for the construction of this new field road, is located in the foothills of the Novohradské hory, about 12 km southeast of the village Trhové Sviny. The chosen location with local names "U hrušky" and "Na 22 hektarech" is located in the eastern part of the cadastral area Dlouhá Stropnice. Proposed practical solution of project documentation of side field road design category P4,0/30 completed with a suitable alternative drainage is based on the theoretical summary of the literature review in this thesis. Other objects - fall culverts and landscaping the surrounding areas are included in the conception of project proposal. An integral part and basis for making the draft was field survey and subsequent analysis of the current status of the affected area.

Právní úprava územní ochrany vod z hlediska množství / Legal regulation of territorial protection of water in terms of quantity

Dvořák, Petr January 2017 (has links)
The thesis deals with the legal regulation of territorial protection of water in terms of quantity, which is contained in the Water Act. I am only focusing on the Protected Areas of Natural Water Accumulation and Surface Water Accumulation Protected Areas as they have significant potential to reduce the effects of drought. Both areas are viewed through common problem, which is the point of view of the amount of water. The legal regulation of the territorial protection of waters in terms of quantity is discussed in connection with other laws. The aim of this work is to answer the question whether the legal regulation of territorial protection of waters in terms of quantity in the Water Act is sufficient to enable the Czech Republic to adapt adequately to the ongoing climate change, that ultimately causes the loss of water. The first part of the thesis deals with sources of legal regulation of territorial protection of water in terms of quantity, further includes the systematics of the Water Act and the Strategy on Adaptation to Climate Change in the Czech Republic (Adaptation Strategy of the Czech Republic). The second part analyses the Protected Areas of Natural Water Accumulation, prohibitions therein contained prohibitions, exemption from prohibitions and damage compensation. The third part deals...

Optimalizace návrhu suchých podlah / Optimizing The Design of Dry Floors

Hlavsa, Petr Unknown Date (has links)
This dissertation deals with the optimization of the dry floor design by solving the innovative floor composition supported by the development of a new floor element, doing so from the point of view of building physics – especially the heat and mass transfer in buildings – with the consideration for the benefits for acoustics. It is aimed at dry floors application to modern timber structure. In the area of heat and mass transfer in buildings, the impact of thermal stability of rooms and its increase in the use of a new floor structure is investigated with the inclusion of a proposed element improving the thermal storage capacity of the floor. All this in the context of ensuring the possible floor heating integration. In the evaluation of thermal stability in rooms, those operating conditions that are accompanied by interrupted heating, are considered to be key. After describing the current state of solving this issue, the main focus of this dissertation is its own development and design of a specific floor element and its integration into the floor composition. An important part of the dissertation consists of related numerical simulations, its own experiment, relevant measurements in the experimental object, and their evaluation.
