Influence of soil matter and different land cover on the runoff process (experimental research in the paired catchments Zbytiny)
Královec, Václav
The doctoral thesis deals with the evaluation of influences of causal factors that significantly affect runoff processes in landscape. The research is mainly focused on the examination of land and soil cover impacts and partially pays attention to the effects of surface drainage and snow cover. The main effort was to find out the extent of influences of each individual factor on runoff from a different type of landscape. In order to find the correct answer, a methodical approach was applied to small experimental paired catchments where the research has been continuously undergoing since the year of 2006 (the presented results have been collected for 11 years of observations). The small experimental paired catchments are located at the foothills of the Šumava Mountains and they represent small area neighbouring catchments of similar physical-geographic and hydrographic conditions. The catchments were selected as the comparative ones where the main differences are the landscape and soil cover. Moreover, the character of surface drainage is regarded to be an important variable. In the catchment area of the Zbytinský Brook, there predominates the grassland which is largely drained by the subsurface drainage system. In the catchment area of the Tetřívčí Brook the dominant cover is formed by the forest...

Influence of climate force forest management on hydrological regime of headwater streams
Pícha, Zdeněk ; Stuchlík, Evžen (advisor) ; Křeček, Josef (referee)
Hydrological functions of catchment area are an important part of the ecosystem. There are three approaches that deal with the issue of catchment hydrological functions. These three approaches are summarized in the work, there are shown the advantages, disadvantages and results of some studies. Hydrological functions of catchment area, especially the runoff process, significantly affect forests growing in the catchment, especially their species composition, age and type of soil. The paper summarizes insights about how that tree species, especially beech (Fagus sylvatica) and Norway spruce (Picea abies) affects runoff, water infiltration into the soil and interception. The next section is then summary the influence of forests on floods, which is not so large as is generally expected. At the end of the work is an overview of some studies dealing with the hydrological balance and runoff processes were carried out in the headwaters of the river Litavka and outline possible further research in this area. Key words: runoff, catchment, forest, infiltration, hydrological modelling, pair catchments
