Use of GIS hydrology tools in water management
Soukup, Matěj ; Štych, Přemysl (advisor) ; Slačíková, Jana (referee)
Use of GIS hydrology tools in water management Abstract This thesis deals with the use of GIS hydrology tools in water management. It is solved on example of Dobříš region. It deals with delineating water protection zones based on digital elevation model. The digital elevation model was derivated from elevation data from the ZABAGED database and then modified by the river network data from the DIBAVOD database. The paper also discusses the use of hydrological functions in the search for potential water sources. During the work was developed a geodatabase containing the data usable in water management. Keywords GIS, water management, hydrologic modelling, protection zones, water resources

Long Term Discharge Prediction in River Hydrometric Profile
Šelepa, Milan ; Menšík, Pavel (referee) ; Marton, Daniel (advisor)
The diploma thesis is focused on the long term prediction of mean monthly flows in hydrometric profile for purposes of reservoir control optimization and optimization of reservoir systems. Discharges were predicted using by artificial neural network method. Predicted flows were statistically evaluated by relevant coefficients and then compared with the measured flows for given river hydrometric profiles.

Factors affecting the total outoff from the watershed and its individual components
MORAVCOVÁ, Lenka
This thesis is focused on the topic of total outflow from the watershed. In the first part water is divided into surface water, subsurface and groundwater, there is also described water circulation, hydrological balance, water retention and water accumulation, as well as characteristics of hydrographic network in the country. There are listed and explained outflow folders and measures to reduce surface runoff. In the second part of this work methods of separating the individual components of outflow, such as CN-method, Kliner and Kněžek method, model SMODERP, HYDROG model, GROUND and MGPM methods are described. In the conclusion it is explained that outflow from the watershed generates not only because of rainfall, but also due to geological, pedological, anthropogenic and other factors.

Out of Asia Minor into Danube Drainage: Phylogeography and colonisation pathways in the loach fish Cobitis strumicae
Majtánová, Zuzana ; Choleva, Lukáš (advisor) ; Reichard, Martin (referee)
The spiny loach Cobitis strumicae is a small bottom-dwelling freshwater fish whose progenitor colonised the Balkan Peninsula from the Near East through the Asia Minor. The current geographic distribution of C. strumicae forms a ring around the Stara Planina (Balkan mountains), inhabitting Danube Basin and coastal rivers of Black Sea and Aegean Sea. Using one marker of mitochondrial DNA (gene for cytochrom b) and one marker of nuclear DNA (S7 gene, first intron), we reconstructed the species distribution and phylogenetic relationship of 44 populations throughout C. strumicae distribution. We also analysed its sister species, C. punctilineata, which lives inside the distribution area of C. strumicae. Aplication of four phylogenetic approaches confirm the monophyly and species statut and endemicity of C. punctilineata, and, moreover, the evidence of secondary hybridization with C. strumicae was found. The network analysis using median-joining method showed deep divergence between the both species. Phylogenetic analyses for cyt b gene confirmed the monophyly of C. strumicae, with internal substructure into at least two well divided lineages, which suggests the process of local speciation. Phylogenetic analyses of S7 gene did not support the monophyly of C. strumicae. Instead, the two separated...

Mathematical models of retention object of urban drainage
Pavlík, Ondřej ; Stanko,, Ing Štefan (referee) ; Pollert,, Jaroslav (referee) ; Prax, Petr (advisor)
This work deals with the use of 3D mathematical models of fluid in water management practice. Using 3D mathematical model was assessed retention tank Jeneweinova, which is situated on a sewer network of the city of Brno and is an important object of urban drainage. Retention basin designed to keep overflow from CSO chambers to Svratka and Svitavský náhon during storm events. Retention tank Jeneweinova is suitable for the assessment, because tank was designed bassed the Master Plan drainage of Brno using 1D mathematical model. Another factor was the physical model, which was build in LVV Vin FAST BUT. And finally, near the retention tank will be installed measurement on the sewerage network, which will be able to verify the results whitch has been predicted in this work. Mathematical model of retention tanks Jeneweinova was build in software FLOW-3D. FLOW-3D is a general purpose CFD (Computational Fluid Dynamics) software for flow of fluid in steady and unsteady mode and uses computational techniques to solve the equations of motion of fluids. This software is mainly used for the calculation of hydraulic fluids, gas flow and heat transfer simulations. Results from 3D mathematical model has been compared with the values in the physical and 1D mathematical model.

Inland waterway transport in the Czech Republic
Honzáková, Tereza ; Novák, Radek (advisor) ; Vavřička, Martin (referee)
Thesis deals with the efficiency of inland waterways in the Czech Republic and its measure which would lead to its greater use. For this precaution is considered a project the Weir in Děčín and without this, the project can not proceed in the construction of other projects in the Czech inland waterways. The first part is devoted to the description of inland waterways as part of the trans-European networks. Furthermore there are institutions in charge of the developement and operation of waterways. Legislation defining the rules to ensure continuity of water transport is also important in the developement and operation. The second part deals with positive relationship between freight water transport and economy of the Czech Republic. I describe in the last chapter of the thesis project the Weir in Děčín and the subsequent project of navigability of the Elbe River to Pardubice and construction of the Danube-Oder-Elbe.

Roman roads in Pannonia
Krištofová, Veronika ; Bouzek, Jan (referee) ; Musil, Jiří (advisor)
Roman road network was built from strategical, politacal and commercial reasons a connected Rome with all parts of the empire. The course in Pannonia is known from multiple sources, from ancient itineraries, monuments along the roads such as milestones and stations and not least from remains of roads themselves. They were divided according their significance and category and from thid derived their management and maintaining. Important source of recognizing of roman roads are vehicles, parst of them were found on archaeological excavations, and they are often displayed on reliefs and funerary monuments. Important meaning of roads was commercial and because Pannonia is an inland province, for transportation there were used terrestrial and river transports. This hung together with transport capacity, speed and time spent on roads.

Water mills, iron mills, saw mills, washboards and paper mills during the flash flood in summer 1714.
Elleder, L. ; Šírová, J. ; Munzar, Jan ; Ondráček, Stanislav ; Lopaur, M. ; Dragoun, Z.
The extraordinary flood disaster in the summer 1714 in the Sázava River, Svratka River, Loučná River and Chrudimka River catchments represents one of biggest known flash floods in the Czech flood history. The flood destroyed not only tens of houses, but also a number of water mills, iron mills and other outbuildings. It was also destroyed many ponds. This fact played an important role during the flood. This event significantly influenced the development of water mills and possibly also the development of a network of ponds in the affected area.
