Proměnlivost rozmístění akumulačních a erozních tvarů uvnitř koryta v závislosti na výskytu překážek a jeho průběhu na různě velkých tocích / Spatial distribution of erosion and accumulation landforms within the river channel depending on the channel course and barriers for various large river

Marková, Jana January 2016 (has links)
The subject of the diploma thesis is the change in the spatial distribution of erosion and sediment deposition landforms within the channel of four different-size rivers, and is based on the morphology of the river channel and presence of barriers. The objective of this thesis was to 1) map the spatial distribution of channel bars and locations of bank scour, 2) define the morphologic characteristics including the position with respect to the location of bends and obstructions in the channel of the individual river reaches, and 3) define common patterns, and explain potential differences between the patterns in the rivers of different size. For the purpose of this study a field reconnaissance was carried out on selected reaches of Sazava River, Litavka River, Kocaba River and Lodenice River. The selected sections represent relatively natural parts of river channels with similar geomorphic conditions. The field survey was carried out in two campaigns - in spring and in summer 2015. The results of the survey indicate that channel bends do not play a primary role in the position and morphology of channel bars and locations of bank scour. However, significant sediment deposition or erosion activity was identified near run-of-river dams. In the surveyed reaches of the Sazava and Litavka rivers, channel...

Návrh revitalizace horního toku Svratky cca km 8,00 - 9,00

Held, Martin January 2015 (has links)
This thesis deals with the study of revitalization measures on upstream of the Svratka River, specifically near the village Herálec. The thesis also contains information about locality, bioregion and basin of Svratka River The main part of the paper examines the modified section Svratka. The goal of this work is to evaluate the current situation and then propose measures that would lead to the revitalization of Svratka River. When drafting work was also used hydrological program HEC-RAS and ATLAS DMT

Revitalizace vybraného úseku vodního toku / Revitalization of River

Kachtík, Michal January 2016 (has links)
The topic of the submitted thesis is to carry out revitalization of a selected section of a watercourse. At first, the actual conditions of the riverbed and its surroundings are described. In the following part of the thesis the description of the newly designed watercourse section is focused. The main goal of the new design is to improve the life conditions both in and around the watercourse as well as to support its self-cleaning process.

Vodní prvky v krajině

Petruchová, Jana January 2014 (has links)
This paper discusses the sources of water in the landscape, divides water features according to various methodologies and describes their nature and functions. It also deals primarily with the development of water loss from the landscape in our country and shows the history and problems of regulating rivers. It points out the consequences of these activities, discusses the historical and current measures - restoration and renaturation of watercourses and the return water back into the landscape. It also discusses the historical development of the country with regard to the aquatic. The case study deals with a model water feature - Bečva river from the source to the mouth. It describes interesting gravel flow. It analyzes the problematic sections of the river and above all the consequences that left a flood in 1997, when there was a change in the morphology of the river bed. At these new locations carried successional development of plant communities and soil creates a new profile. The author's thesis deals with these sites, especially ripping shores and gravel benches on Bečva in Osek. The paper describes the concept of river flood protection of the Bečva river, technical proposals and revitalization . The author evaluates these studies. It also shows the differences regulated and refolded channel.

Návrh revitalizace části Knínického potoka / Project of revitalization part of Kninicky brook

Vyplel, Adam January 2020 (has links)
The diploma thesis is focused on the proposal of systematic revitalization of the selected section of the Knínický brook in the cadastral area of Veverské Knínice. It is a straight, very deep channel due to technical adjustments in the past. The HEC-RAS program verifies the capacity of the channel for the Q100 flow. In this way, it was found that the channel has very high capacity so a new route with Q1 flow capacity was designed. Due to the height conditions, the design also included three boulder chutes. Subsequently, the vegetation accompaniment and bank stands were suitably supplemented.

Doplnění protipovodňových opatření v povodí Salašského potoka / Flood control measures in the Salašský potok basin

Stolářová, Alena January 2013 (has links)
This thesis deals with the addition of flood protection measures in the Salašský potok basin. Working closely related to the previous bachelor thesis on Flood protection in the Salašský potok basin. Detail deal with left tributary Salašky - Modranský potok -which runs through the town Modrá, to be occupied by 6 small cascade of water reservoirs. The work is divided into two parts. The first part describes the actual parameters of the tanks and their assessment of the possible spill-over and is solved their overall transformational effect in the basin. In the second part of the thesis dealt with the tank as a semi tank in response to N-leté water and searched their design parameters.
