Retention Reservoir Design in the Police Cadastr
Hadaš, Zdeněk ; Menšík, Pavel (referee) ; Starý, Miloš (advisor)
This thesis deals with the river basin flood protection Loučka. The goal of the thesis is to assess the need of flood control measures supplement in the watershed. The first part deals with exploration of river basin, acquiring geographic factors and obtaining information about the topic, establishment and application of rainfall model used for solving the problem. The second part deals with improving of flood protection at critical selected places by using design of reservoir system with retention effect and by increasing river basin capacity. For basin schematisation was used ArcGIS program and the simulation of rainfall-runoff process was made by Hydrog program.

Flood control measures in the Nectava River basin
Boháč, Ondřej ; Menšík, Pavel (referee) ; Starý, Miloš (advisor)
This bachelor’s thesis deals with the flood control in the basin Nectavy. The aim is to assess the need enhance flood control in the basin. The work is divided into two parts, the first part deals with own description of the basin and the second part with data processing in programs ArcGIS and Hydrog. The description of the basin consists of a personal acquaintance with the basin and its surroundings, interview with residents of communities located along the river and description of geographic factors in the basin. After obtaining all necessary informations will be basin schemed in the program ArcGIS where it will be divided into smaller sub-basins which will require for further work. The output from the previous step is used for processing in the program Hydrog, to work in this program is also needed to calculate the replacement intensity of rains. Simulation in the program Hydrog are obtained critical period of rains and set N-year flows. In the end the obtained values of peak flows are compared with the actual flows and identifying critical points are assessed for possible flow and flood.

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.

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.
