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...
