Monitoring of Underground Construction with Low Overburden
Lossmann, Jaroslav ; Ožana,, Štěpán (referee) ; Hrubešová,, Eva (referee) ; Horák, Vladislav (advisor)
Geotechnical monitoring (GTM) is an essential part of the observation method. In the principle it is the measurement and monitoring of preselected magnitudes – their changing values in the course of the constructing process and their partial evaluation. On the measured values basis the correctness of designed structures and technological processes is verified, optionally new technical and organizational measures are adopted in order to guarantee the continuous and safe constructing course. The main goal of the dissertation is to analyze the current state of the problematics and evaluate the methods of GTM in underground structures with low overburden, including suggestions and recommendations for procedures. In the framework of knowledge, practical experience and data analysis, the basic types and procedures of monitoring elements of underground structures with low overburden will be defined.

Concept of stream restoration in urban area
Jonáš, Miroslav ; Matoušková, Milada (advisor) ; Šobr, Miroslav (referee)
This diploma thesis presents a restoration study of a small watercourse in the urban area, specifically the section of Bouřlivec - a tributary of the Bílina River, crossing the municipality of the village Lahošť. The restoration study was carried out as a part of the contract research of the Faculty of Science, Charles University in Prague and Povodí Ohře, state enterprise. The final report of this research is part of the cited literature at the end of the qualification thesis. Among the main objectives of the study was the design of restoration concept that will primarily lead to: 1) improving the hydromorphological and ecological state of the stream, 2) increasing flood protection and 3) increasing recreational usability in close proximity to the watercourse. A total of 11 cross section profiles within a longitudinal profile with a length of approx. 454 m were geodetically measured using the total geodetic station. A modification of the new method of calculating the roughness of cross section profiles was proposed and for each profile the current and design maximum flow capacities were calculated. As part of the longitudinal profile, a mosaic of 4 variant solutions was designed, which alternate regularly within the section of interest. The grain size analysis of the river substrate was held in...

Differences in morphology of the valleys in the Jizerské hory Mts.
Hložek, Martin ; Engel, Zbyněk (advisor) ; Hartvich, Filip (referee)
This Master thesis focuses on a river network characteristics in the Jizerské hory Mts., northern Bohemia. This part of the Czech Republic represents an area, which was during Tertiary and Pleistocene affected by neotectonic movements. Therefore, 30 longitudinal profiles of selected rivers were constructed to determine areas influenced by tectonics most intensively. These profiles were classified into four categories according to shape of profile curve. Also valley cross sections were made on five selected rivers. Additionally, the Jizera and Jizerka rivers were studied to assess changes of their streams in the period of 19382012. On the north-western (the Jeřice river catchment) and northern (the Smědá river catchment) slopes of the Jizerské hory Mts., areas most affected by neotectonic movements were detected. Tectonically controlled valley cross sections are distinctive on the Smědá, Jizera and Kwisa rivers. On the Jizerka and Jizera rivers, lateral erosion rate ranges up to 0,5 m/year.

Modelling of flood event runoff and flood lines in Želivka river
Mudra, Jiří ; Roub, Radek (advisor) ; Heřmanovský, Martin (referee)
Nowadays, the issue of floods and flood protection is very reflected theme which is dedicated to the thesis. The first part deals with the gathering and the processing of relevant information, the emphasis is on the development of basic questions about flooding and flood protection because of importance for understanding its. The next part of thesis provides a description of the catchment Želivka which involves the interest area which is bounded swells water reservoir Švihov at 41.6182 Km and dykes of water reservoirs Sedlice at 63.8893 Km. The next, the thesis also discusses the modeling of steady flow of flood flows and modeling flood lines in the area of interest. For the simulation are used ArcGIS 10.2 with overlaid of GeoRAS, HEC-RAS 4.1.0 and the description of creating a model for the assembly are used the digital elevation model fifth-generation, transverse profiles of stream, longitudinal profile of stream and roughness of stream and inundation and geometry of objects on the stream. The outcome of this work are maps of inundation in selected sections on the stream, in particular in areas with existing buildings.

Determination of floodplains and hydrotechnical assessment of Říčanský water flow
Bezděková, Veronika ; Roub, Radek (advisor) ; Marie, Marie (referee)
This thesis deals with determining the flood lines and hydrotechnical assessment of the Říčanský water flow and objects that interfere with the flow profile. Hydrotechnical assessment preceding hydrological study of catchment. The basis for this work was digital model relief Czech Republic, which obtained from Airborne Laser Scanning. This method is considered to be of the most accurate methods for altimetry data obtained, but the near-infrared laser beam used in this method cannot penetrate water masses. The result of this problem is error as the extracted cross sections lose a significant portion of their flow area. These errors can be removed to recess the channel using specialized software Crosolver tool. For hydrotechnical assessment is used hydrodynamic model in HEC-RAS. On the basis of results are determined the flood line for N-years flows (5-years flow, 20-years flow and 100-years flow). The final part of this work deals evaluation of hydrotechnical assessment Říčanský water flow, object and floodplains.

Determination of floodplains and hydrotechnical assessment of Mastník water flow based on the DMR 5G data
Čápová, Pavlína ; Roub, Radek (advisor) ; Havlíček, Vojtěch (referee)
This work engages in the watercourse called Mastník. It focuses on the determination of flooded areas for couple of series (Q5, Q10, Q50, Q100) and hydro-technical assessment of particular objects. The chosen section is situated on cadastral area of town Sedlčany in the Central Bohemia region. Its length is 1.973 kms and there is located 5 water management objects reaching to the flow profile of the watercourse.
The data for this dissertation has been gained by the Czech State Administration of Land Surveying and Cadaster. It is about the digital relief of the 5th generation of aerial laser scanning. The laser rays are not capable of penetration the water surface, and thus describe the shape of the water-sources bed. So the tool called CroSolver was used to dig the water-sources bed. Then the hydrodynamic model has been created in program called HEC-RAS.
From the results of hydrodynamic model then was evaluated the real water-technical state of the object.
The outgoing data (dots defining the flood range to the surroundings) was after then inserted to the program ArcMap. Here the flood lines and from them the flood zones were created based on the particular series of the flows.

Determining floodplains and assessment of water facilities in the selected section of the watercourse Lužická Nisa
Lišková, Karolína ; Roub, Radek (advisor) ; Marie, Marie (referee)
This master thesis focus on determinig the flooding inundation of the selected area of Luzicka Nisa, flowing through the city Hradek nad Nisou. The work is based on the field survey and the information about the area, on this basis it describes the watched area in interaction for determing the flooding inundation. The thesis is split into the text summary and determing the flooding inundation of the selected part of the river Luzicka Nisa. The text summary sums up the problematic of flooding. It mentions the history, the prevention against flooding, the factors influencing their formation. The flood stages, the flooding inundation and the flood control plans. The second part focus on the determining the flooding inundation at the N year flows by using of the program HEC RAS 4.0 and the ArcGIS extension HEC-GeoRAS. The determined flooding inundation was modeled on the basis of the data of cross profiles, N year flows and water facilities and then exported on map data.
