Návrh rekonstrukce poškozeného koryta toku Rusavy v obci Rusava / Design of reconstruction the damaged streambed Rusava in the village Rusava

Zelíková, Gabriela January 2014 (has links)
Design of reconstruction the damaged streambed Rusava in the village Rusava The task of this thesis is to evaluate the existing capacity of the streambed and design the reconstruction of Rusava river km 26,000 to 28,230. Rusava watercourse takes place in urban area of village Rusava in Zlín region. Channel revetment was badly damaged by floods in July 2011. The assessment of the current state of the watercourse was based on personal visit of the place and taken photos. Current state was modeled in HEC – RAS 3.1.3 software. The reconstruction is designed according to the assessment of the current river channel condition and also contains proposals for new buildings on the river.

Hodnocení diversity společenstev makrozoobentosu v kontextu kvality fyzického habitatu vodnich toků / Assessment of macroinvertebrates diversity in contex of physical river habitat quality

Nováková, Barbora January 2018 (has links)
Research of macroinvertebrates is currently an important part of the assessment of stream quality. Basic characteristics influencing macroinvertebrates communities in the streams are elements from the external environment influencing streams, specifically basic geographic parameters of the site, land-use in the catchment and characteristics of the banks. These elements have a considerable influence on effect of the basic parameters in the stream, which are flow, sediment structure, input of organic material and pollution. Research part of the thesis is about the parameters influencing macroinvertebrates communities. Research area of this work includes three different catchments in the upper part of Blanice catchment area near Prachtice. There is one nature stream with forest in it's catchment, stream with a predominantly meadow basin and last stream is characterized by two distinct stretches - a revitalized section and a section with concrete bottom. The subject of this diploma thesis is evaluation of diversity of macroinvertebrates communities in all streams in the research area. Thesis evaluate communities of macroinvertebrate using a wide range of indexes (BMWP score, ASTP index, EPT index a diversity indexes) and compares their diversity by using rank-abundance graph. All results are summarized...

Návrh bypassu v rámci protipovodňové ochrany města Prostějov / Design of bypass within the flood protection the city Prostějov

Juráňová, Barbora January 2015 (has links)
The target of diploma thesis is to design and review flood protection in Prostejov, especially for district Vrahovice. Flow capacity of river Romze will be determined too, because the river flows through the area of interest.

Návrh malé vodní nádrže s retenčním účinkem v katastrálním území obce Police. / Retention Reservoir Design in the Police Cadastr

Hadaš, Zdeněk January 2014 (has links)
This thesis deals with the river basin flood protection Loučka. The goal of the thesis is to assess the need of flood control measures supplement in the watershed. The first part deals with exploration of river basin, acquiring geographic factors and obtaining information about the topic, establishment and application of rainfall model used for solving the problem. The second part deals with improving of flood protection at critical selected places by using design of reservoir system with retention effect and by increasing river basin capacity. For basin schematisation was used ArcGIS program and the simulation of rainfall-runoff process was made by Hydrog program.

Návrh profilu pro zachycení povodňového pláví na řece Bečvě / Design of the control profile to retain flood debris at the Bečva river

Lokajová, Hana January 2015 (has links)
The work deals with a theoretical description of mathematical model and practical aspects of model simulation. Subsequently, it solves the current flow and the two design versions of the flowing debris trap profile. For the original channel and for the two designed versions two simulations were done for the flows of Q2 and Q5. As part of the work the theoeretical calculation of velocity in two cross sections of the existing channel was realized for the existing channel, which were due to calibration of the model. Results were compared at the same cross sections in the existing channel simulation solutions. Simulations are created in FLOW-3D. The purpose of this thesis is to determine whether the construction of trap profile is feasible.

Zpracování studie revitalizace malého zemědělsko-lesního povodí / Revitalization study for small agricultural-forest catchment

ČASTA, Jiří January 2014 (has links)
Revitalization generally are activities leading to the recovery of ecosystems in the landscape and their stabilization. In this thesis are proposed changes for revitalization of small agro-forestry basin stream called Branná significantly disrupted trough conditions, the banks and a river basin, including throughput migration of aquatic animals.

Navazující opatření na vodohospodářské řešení vodní nádrže Těšetice / Follow-up measures for the water management solution of the Těšetice water reservoir

Žiaček, Tomáš January 2019 (has links)
The main aim of the thesis was the liquefaction of Únanovka streamflow under the Těšetice dam with the focus on suitable flood protection of the villages of Těšetice, Bantice and Práče.The thesis evaluates the existing condition of the Únanovka streamflow in the river mileage 1.6593 – 6.4103. Calculation of the streamflow capacity was carried out per 1D mathematical model in the HEC-RAS programme for the selected N-year flow from the ČHMÚ hydrological study. Final value of the improved drainage from the dam was determined together with the possible value of water collection. Within the thesis the hydro-ecological monitoring of the watercourse was carried out (HEM analysis 2014).

Tlumení energie proudu vodním skokem v prostoru rozšíření koryta / Hydraulic Jump Energy Dissipation in the channel extension

Pospíšil, Radek January 2020 (has links)
The diploma thesis is focused on the evaluation of the suppression of supercritical current energy in the area of the river bed extension. The hydraulic model was used to simulate current conditions for different variants of river bed arrangement. Individual variants were then evaluated according to the relevant criteria and compared with each other. Results can be applied in hydrotechnical practice based on model similarity.

Návrh víceúčelové nádrže v k.ú. Popovice / The design of the multipurpose small water reservoir

Pitka, Roman January 2013 (has links)
Master´s thesis aims to design multipurpose reservoirs in the river basin Žlebovský potok in cadastre Vysoké Popovice. The main purpose of the reservoir will be improving the drainage conditions in the basin of the river and revitalization. The reservoir will be designed according ČSN 75 2410 – Malé vodní nádrže. The master´s thesis consists of a text section, hydraulic calculations and graphic attachments.

Návrh protipovodňových opatření v povodí toku Březnice. / Flood Control Measures Design in the Březnice Creek Basin

Zárubová, Kamila January 2014 (has links)
This thesis deals with the flood control. In particular, the design of a set of small water reservoirs with retention effect (polders) and their effect on flood flows. The work is divided into two parts, the first part refers to the bachelor thesis. In this thesis is description of the catchment, rainfall-runoff process and the evaluation of the ratio. That was got the necessary information for the design of polders. This is an abbreviated repetition of the contents of the thesis, which is a continuation of this work. The second part deals with the specific design of two reservoirs, including hydro calculations and drawings. For this work were used ArcGIS - ArcMap, Hydrog and to create drawings AutoCAD 2010.
