Protection of the built-up area of the municipality by the proposal of water management measures in the river basin
Majkus, Martin ; PhD, Ing František Pavlík, (referee) ; Dumbrovský, Miroslav (advisor)
The aim of this paper is to evaluate the important factors that determine the flood risk of the built-up area in the surveyed location. Also, it is necessary to assess the intensity of erosion treat to the soil and then propose comprehensive protective measures in the catchment areas of critical points and profiles, which will reduce these unfavourable values. The introductory part will summarize the existing knowledge and methods for determining the values of surface runoff and the degree of erosion risk. In the design part, surveyed locality analysis will be proved. Furthermore, the suitable water management measures will be proposed. The measures will ensure the protection of built-up area of the municipality and improvement of erosion conditions. For analysis of the area and for propose of measures were used ArcGIS-ArcMap and DesQ-MaxQ software. Obtained information was then processed in MS Excel and Word editors.

Flood control measures in the Loučka Catchment
Hadaš, Zdeněk ; Marton, Daniel (referee) ; Starý, Miloš (advisor)
This thesis deals with the river basin flood protection Loučka. The aim to assess the need tu supplement flood control measures in the watershed. The first half deals with exploration of river basin, providing geographic factors and obtaining information on the topic. The second part deals with the establishment and application of rainfall model to solve the problem. For schematisation basin was used ArcGIS program. Rainfall simulation process were calculated critical duration of rainfall intensity and spare set of N-year flows. It was by searching for critical points and assessed for possible overflow.

Verification of the dependence between rain intensity and N-year flow for selected river basins with measurement
Tomášek, Lukáš ; Zemanová, Šárka (referee) ; Kozel, Tomáš (advisor)
The diploma thesis deals with the verification of various precipitation events in the selected river basins with measurements. As part of the work, schematization is for a given river basin made and a precipitation-runoff model is created and calibrated based on measurements in the final profile for 2 variants of calculations. Alternative rain intensities with different periodicity and duration are then tested on the calibrated precipitation-runoff model to achieve the required flow rate Q20. Finally, the aforementioned results are evaluated and recommendations are made from them.

Vliv drenážních systémů na odtokové charakteristiky vybraného povodí
ČERMÁKOVÁ, Veronika
This bachelor thesis deals with drainage, especially drainage by drainage systems and their impact on various aspects of nature. The introductory part explains what drainage systems are, what they are used for and what they look like. Furthermore, the history and occurrence of drainage systems in the world and also in the Czech Republic are described. Subsequently, several chapters are devoted to methods of drainage and then a description of drainage systems. The following are the impacts of drainage systems on the water regime of the river basin and on the environment. After processing and analyzing data on runoff and precipitation conditions to a selected catchment area of the Jenínský stream, their behavior during the hydrological years 1984-1985, 2005-2007 and 2011-2013 was compared. In these years, the runoff coefficient was calculated, and subsequently double sum lines were constructed, which show the purpose of identifying changes in the long-term balance of precipitation and runoff.

Design of erosion and flood control measures in the study case area responding to climate change
Mrázek, Vojtěch ; Larišová,, Lucie (referee) ; Sobotková, Veronika (advisor)
The aim of the work is to design anti-erosion and flood protection in the area of interest KÚ Lukavec to the current state and responding to climate change. At the same time, it is necessary to assess the degree of erosion threat to the soil and analyze runoff conditions in critical areas. The introductory part summarizes information about the studied area and methods for calculation. The erosion analysis is processed in the design part and suitable anti-erosion and anti-flood measures will be proposed. DesQ-MaxQ software was used to calculate the runoff conditions, graphical outputs and analysis of erosion conditions were created in the ArcGIS environment.

Mapping Of Litavka Basin Using GIS
Barešová, Magdalena ; Matějíček, Luboš (advisor) ; Benešová, Libuše (referee)
The purpose of this work is the use of the Geographic Information System (GIS) for a model evaluation of a selected area of Litavka basin. The theoretical section focuses on the description of GIS, GPS and selected GIS projects (ZABAGED, National inventory of contaminated sites, ArcČR500). The practical area focuses on processing the data. There were several thematic layers created including: the digital terrain model (DTM), thematic layer on the slope, aspect to the north, and a layer of aerial photographs containing current and historical status. The project was completed with a thematic layer of test sampling profiles. The practical part included a chemical analysis of water samples from Litavka carried out in Laboratory of water protection of the Institute for Environmental Studies. The purpose was to demonstrate the influence of rural agglomeration on water quality changes. The quality grade of the flow was determined by appointed indicators according to the Czech Technical Standard CSN 75 7221 Water quality. All data was entered into the GIS project. Key words Geographical Information System, mapping, Digital Terrain Model, Global Positioning System, Litavka, river basin/watershed, quality of surface water
