Analýza odtokových poměrů ve vybraném povodí
Dufek, Václav
The diploma thesis analyzes and evaluates the drainage conditions together with the retention potential of the landscape in the parts of the Bělský potok basin, which is located in the south of the Pardubice Region. The theoretical part of the thesis contains the elaborated literary research on the basis of the study of the specialized literature mentioned on the given issue, and also the characterization of the selected river basin. The practical part includes processing of underlying materials and data preparation in ArcGIS 10.3.1 using the ArcMap, ArcCatalog and ArcToolbox integrated applications suite. Processed data are the input information for the calculation of hydrological characteristics by the DesQ-MAXQ model.The resulting calculated values of maximum flows, specific flows, potential retention in the basin, concentration time, amount of water retained for each sub-basin are presented in the form of map outputs.

Runoff circumstances and changes in river basins of the Czech Republic and abroad
RYŠAVÁ, Radka
This bachelor thesis is oriented towards the drain, its origin, the elements and factors that affect runoff. It is focused on the hydrosphere, the hydrological cycle, and finally focuses on changes in runoff conditions in the Czech Republic and abroad, depending on the climate and the source water levels of rivers. Between sources of water levels of rivers include, eg rainfall, melting snow, subsurface water, melting glacier. Furthermore, this bachelor thesis deals with the bypass ratio and changes in the basin of the Czech Republic and abroad, and is written in the form of a literature review. It defines the basic concepts of the problem and explains in detail the individual components of runoff. Among the ingredients drain we classify surface runoff, subsurface and groundwater runoff. Further it also describes the hydrological cycle, which can be small or large. The water gets to the earth surface in the form of precipitation, for example such as snow or rain. These collisions affect runoff.
