Analýza srážko-odtokových vztahů na vybraném povodí
FREJLACHOVÁ, Dagmar
This bachelor is focused on analysis of rainfall-runoff relationships. The theoretical part of the thesis defines water in nature, hydrological balance, the rainfall-runoff process, and characteristics of its parts. Rainfall-runoff events and ways of analysing the relationships between rainfall and runoff are also described. The practical part is focused on analysis of rainfall-runoff relationships on the catchment of Jenínský stream in the hydrological years 2011-2013. Description of the catchment, processing of the rainfall and runoff data, creating of hydrographs and runoff coefficients for each hydrological year and selected rainfall-runoff events are part of the thesis as well.

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.

The evaluation of land use changes in last 50 years in the catchment of Jeninsky stream.
CEPÁK, Martin
It is in human nature to adapt the environment for his needs and wishes. Politics, technology and society as a whole went trough dramatic changes in Czech Republic in last 50 years. These changes approved naturally on land utilization too. This research is focused on the evalution of land use changes in last 50 years in the catchment of Jenínský stream. The research is based on photogrammetric scans from years 1952, 1974 and 2005. Polygon maps of land use in GIS were elaborated from these scans. Outputs of these maps were subsequently analysed and mutually compared.
