Analysis of nutrients concentrations in waters and their transport from selected catchment
 JIRKOVSKÁ, Veronika
The aim of this study was to analyze the presence of the trend of long-term time series of concentrations and losses of nutrients and their descriptions. The concentrations of nitrogen and phosphorus compounds were evaluated. The analysis was performed on selected catchment of large, medium and small areas. All observed catchment are located in the basin of dam Švihov. Trends were tested using non parametric methods - Mann-Kendall test, Seasonal Mann-Kendall test and Kendall's correlation coefficient . In this study there are generally described monitored cycles of nutrients, nitrogen and phosphorous. There are also characterized the factors, which effect leaching of these nutrients to water (from the catchment). The paper also outlines the progression of water quality in the Czech Republic, which was influenced by political and economic changes in Europe in the second half of the 20th century.

Concentration of nutrients and their transport from catchment area
 JIRKOVSKÁ, Veronika
This work aims to approach the problems of the increasing concentrations of nutrients in the catchment area and then in the entire complex of the natural components, especially in water. In most of my work I deal with the problematic nutrients that affect the quality of water, that means nitrogen and phosphorus. Next there is also described the cycle of the both observed nutrients in nature and also characterized the factors that influence the leaching of these nutrients out into the water (from catchment area). This has also the connection with the evaluation of human activities that significantly interfere in the development of the landscape components and the consequences that come with these activities mainly relating to the pollution of water structures. My work is also briefly focused on the situation of the development of water quality in the world and in the Czech Republic in conjuction with the way, how water was and has been influenced by human activities.
