2D numerical modelling of shallow water flow in floodplains
Monhartová, Pavlína ; Sýkora, Lukáš (referee) ; Dráb, Aleš (advisor)
The aim of the thesis is hydraulic computation of shallow water flow in floodplains with using 2D numerical modelling. Processing river is Dyje in the south of Moravia in location Břeclav. For model creation is necessary to know the software, accumulate input data and prepare model input parameters. Output data are process to form of maps water depths and maps water flow velocities.

Regulation of the river
Varga, Tomáš ; Pilařová, Pavla (referee) ; Šlezingr, Miloslav (advisor)
This bachelor thesis deals with the evaluation of current state of selected part of the river and deal with regulativ of river. The work is conceived on four different levels.The first on eis describesing general characteristics of the selected selection. Second concern calculation of capacity and following river regulativ. Next part contains proposal of vegetation belt. The last part is about drawing of current state and also river regulativ features.

The revitalization project of the selected section of the watercourse
Skřížala, Lukáš ; Blahuta, Jaroslav (referee) ; Šlezingr, Miloslav (advisor)
Bachelor thesis deals with revitalization in the selected section on the watercourse Ondřejnice. Purpose of the revitalization is especially the removal of the migration obstacles creating conditions for the natural development of the trough, without any need of standard maintenance by the flow manager. In the bachelor thesis have been replaced some stone steps by the boulder slip, the wooden gradients have been replaced by some new wooden steps with holes for the migration of animals. Then were in the watercourse designed some Fish shelters. At the places where the gradient adjustment will take place, will be designed a new vegetation accompaniment. By the design of the revitalization measures there will be no worsening of the drainage ratios.

Design of river stabilization structures at the Bečva river in OSek
Lokajová, Hana ; ing. Zedníček (referee) ; Julínek, Tomáš (advisor)
This bachelor thesis is dedicated to the solution of channel recessing in Osek nad Bečvou. One part deals with the evaluation of historical perspective of the area of interest. In the next part of this thesis the transport of sediments is described. The following part contains of an evaluation of current state of the selected part of the river Bečva and deals with a regulation of the river. In the end the theoretical suggestion of protective measure is developed.

Assessment of the silting streambed river Český potok in the village Čechy pod Kosířem
Blaha, Josef ; Smelík, Lukáš (referee) ; Uhmannová, Hana (advisor)
Bachelor thesis deals with the problematic of clogging the flow of Český potok at village Čechy pod Kosířem. Work assesses the current state of the flow modification made in the 70s of the last century in terms of flow and object capacity and in terms of the state of the riverbed fortification. Thesis also includes the evaluation of the stability of the flow bottom focused on the clogging the flow in the section modified to a rectangular transverse profile. Based on the performed assessment, precautions eliminating the clogging the flow are suggested. Thesis contains drawings of the current state of the water flow and drawings of suggested precautions.

Changes of natural organic substances within hydrological extremes in headwater areas
Bejčková, Marie ; Matoušková, Milada (advisor) ; Vlček, Lukáš (referee)
Diploma thesis is focused on changes of natural organic matter within hydrological extremes in headwater areas of the upper Vydra. The increace in these concentrations and increased transport to surface waters negatively affect the environmental and social environment. The main aim of this work is to analyse the amount and variability of organic metter in relation to selected runoff events with clarification of these relationship. The change in the amount of concentrations and variability of Dissolved Organic Carbon (DOC) was evaluated with respect to the preconditioning of the catchment (over a period of 14 days) and the influence of hydroclimatic conditions during the episodes. The dependence of each variable on DOC concentrations was also examined. The dependence of parameters (water temperature, conductivity, flow rate, pH, Dissolved Oxygen, Dissolved Organic Carbon concentration) within the campaigns and the subsequent similarity of the profiles were also investigated. The data for this work were provided by the Department of Physical Geography and Geoecology, Faculty of Science, Charles University. The evaluating of relationship and processes was determined, for example, using Principal Component Analysis (PCA Analysis), hysteresis loop or Pearson's correlation coefficient. The greatest...

River regulation with regard to the flood protection and revitalization
Bohatý, Martin ; Julínek, Tomáš (referee) ; Duchan, David (advisor)
This bachelor thesis focuses on the evaluation of the current state and proposal of the river Bobrava, which can be found in the district of Brno-venkov. Among other things, it flows through the municipality of Želešice, our locality of interest. The work is divided into theoretical and practical parts. The theoretical part is devoted to water flow in an open channel and basic calculation methods. The practical part describes the site of interest, including hydraulic calculations in the HEC-RAS program and the proposed treatment itself. Hydraulic verification of the design and its evaluation is also an integral part of the work.

Assessment of runoff conditions on flow in the Morava river basin
Holá, Lucie ; Niklová, Věra (referee) ; Uhmannová, Hana (advisor)
The diploma thesis deals with the design of nature close to the flood protection of the city Prostějov at the confluence of the watercourses Romže and Hloučely and the flow Valova (Romže). In canculations there was solved capacity of individual sections and canculation of levels for one-year, five-year and twenty-year flow. For canculations there was used one-dimensional mathematical model HEC-RAS 5.0.3. Determination of roughness of bottom and slopes was based on personal visit. The result of this diploma thesis is evaluation of current state and proposal of a nature close to the flood protection in the individual streams in the city Prostějov. The thesis contains the calculation part and the drawing part documenting the proposed measure.

River adaptation with Civil 3D and HEC-RAS
Filípková, Monika ; Julínek, Tomáš (referee) ; Duchan, David (advisor)
This bachelor thesis deals with the evaluation of the current state of the selected section of the Morava river around the city of Olomouc and the subsequent modification and desing of the flood protection. In the first step, hydraulic flow verification using CIVIL 3D and HEC – RAS is performed. Based on the results of the 1D model, proposal river adaptation is then also executed with the aim to incerase the flow capacity and to reduce the water effusion.
