Reconstruction of Track Section with Design of Technological Procedure of Works
Hospodka, Pavel ; Brůha, Bohuslav (referee) ; Svoboda, Richard (advisor)
The aim of the thesis is a reconstruction of a double-track railway Hrušovany nad Jevišovkou – Brno in the section of km 145, 9 – 149, 0. The thesis contains modification of geometric parameters of the railway and reconstruction of the superstructure. A trackspeed should be newly increased up to 100 km/h in this section. Design of a railway crossing and railway stop in village Troubsko according to valid legal enactments is also included in the thesis. Within the reconstruction, a re-conditioning of the current drainage and a design of work technology is drafted.

Design of Optimization of Track Section Branná - Ostružná in km 12,677 - 15,3
Veselý, Miroslav ; Burda, Petr (referee) ; Plášek, Otto (advisor)
The objective of my thesis is to propose a given section of line optimization of geometrical parameters of tracks, and also to increase the line speed. Another task is to design a suitable structure of the railway bed due to the speed category of track and traffic load, and propose a suitable design sleeper base. In addition to design a type of construction at level crossings, the crossings without AD then add necessary view triangles.

Landscape Management in the Village Křeč
Dvořáčková, Hana ; Syrovátka, Oldřich (advisor) ; Lukášová, Tereza (referee)
This Bachelor's thesis deals with landscape Management of the administrative boundaries of the village Křeč. The aim of the thesis is to gain and draw up documents for management decision making in matters of long-term sustainable drinking water supplying for the village. It will be examined hydrological water area network, identified quality of drinking water and found potential sources of drinking water pollution. Within the municipality Křeč will be performed research concerning the issue whether the landscape is able to hold water when exposed to climate change. The research will be focused on monitoring the groundwater level. This will be achieved through underground wells - probes, rainfall measurement and brook flow at the local brook measurement. It will be proposed an appropriate measure that will lead to drainage stabilization, prevention against erosion occurrence and in the end will improve the resulting landscape.

Artificial drainage systems in the Czech Republic and their impact on catchment water regime
ČERVONYJ, Jakub
In this diploma thesis the issue of drainage system influence on water regime of catchment area was solved. The aim of the thesis was to analyze influence of drainage system on specific catchment area using mathematical, hydrological and statistical methods. In the teoretical part, the thesis describes the issue of drainage (specifically the drainage system of area of the Czech republic) and the influence of drainage system on water regime. In the practical part an analysis of the catchment area of Kopaninský creek and subcatchment areas P6, P52 and P53 was performed. At all of those areas, certains parts are dewatered by subsurface systematic drainage system, those parts are described in detail. The runoff coefficients and specific runoff from each subcatchment areas in different time interval were calculated and observed. Runoff separation and precipitation-runoff situation analysis were performed. The results are evaulated in the chapter Results and Discussion.

Revitalization of peatbogs of the Šumava National Park and its potential in conservation education
KAIFEROVÁ, Olga
The peatlands belong to unique biotopes of our landscape. Great attention is paid to their protection, especially due to the fact that they are home sites for rare animal and plant species as a whole they are very important for the general diversity of the landscape, and they play a vital role in the water regime of the landscape as well. More than 70 % of peat bogs were drained in Šumava in the past. Drainage leads to a general distortion and degradation changes (in peat, flora as well as fauna). The programme known as the "Programme of revitalisation of Šumava wetlands and peat bogs" is focused on the rescue of the spots affected. Its main aim is the the rescue and protection of spoiled wetlands and peat bogs, as well as a general remedy od the distorted water regime in the landscape. Within voluntary activiries, so called Days for Peat-bogs, the public can get involved into the peat bog recovery.

Influence of rainfall drainage events on nutrients loss in river basins
STREITOVÁ, Eva
The aim of this bachelor thesis is to clarify the influence of rainfall drainage events on nutrients loss in river basins and which of these rainfall drainage events are the main reason for the loss. This thesis describes the elemental nutrients ( nitrogen and phosporus belong here) occuring the most often and in the biggest amount in our waters. The thesis also describes their occurence in waters and follow-on eutrophication of waters. Further, the factors influencing the drainage during the rainfall event are defined. These factors determine, by their activity, what aliquot part of rainfall drains on the surface, when and in which sequence the individual aliquot parts of rainfall come to river basin, whether water runs off the surface quickly or whether it soaks into the soil. These processes implicate the well-known cycle of water in the nature, which is consequently described in this thesis.

The influence of drainage systems on catchment water regime
ČERVONYJ, Jakub
The influence of drainage systems on catchment water regime was dealt within this bachelor´s work in the form of literature review. The water regime of landscape as well as components of hydrological balance in catchment was described in the first part. Basic concepts of agricultural drainage systems are described in the second part. The last part of literature review was devoted to the influence of drainage systems on water the characteristics of Jenínský strem catchment, where the systematic drinage systems were built in history. The description of the area of interest includes the evaluation of functionality of drains after 30 years of presence in the catchment, executed by field research.

Draft of the project documentation of field road particulary reflecting water retention and accumulation in the land consolidation
MARKOVÁ, Dana
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.
