Stanovení základních složek hydrologické bilance lesního mikropovodí v pahorkatinné oblasti
 Deutscher, Jan
The water-balance of forested microwatersheds was addressed with the main goal being the evaluation of temporal dynamics of intraday flowrate in relation to woody vegetation. The work was solved on two watersheds with different vegetation conditions but similar natural conditions, in TFE MF Křtiny. The effect of woody vegetation on flowrate was evaluated from following continuously parameters - flowrate, air temperature, rainfall, stand transpiration and soil moisture - all measured continuously during dry periods of the growing season on 2010 - 2012. The results indicate that under described conditions, the flowrate is mainly affected by transpiration processes of woody vegetation. Depending on daytime stand transpiration causes either a decrease in flowrate (on average up to 20% during the day) or an inverse increase during the night.

The antierosion precautions as the element of the ecological landscape stability
 LIŠKOVÁ, Barbora
The subject of this thesis is the erosion control as the element of the ecologic stability. The target of this thesis is to determine the amount of the soil, which is being lost from lands in Štěkře cadastral area as consequence of the surface runoff. I use the universal soil loss equation from Wischmeier and Smith for calculations. I also calculate the cubature runoff from the micro catchment area according to Čerkašin and the transport of floating solids according to Williams and Berndt. I propose the antierosion precautions for lands which have got the measure of erosion bigger then acceptable value. I compare all findings before and after the antierosion precautions.
