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.
