Zjišťování odtoků vody z lesních pozemků měřením průtoků vody ve vodním toku.
 TROJÁKOVÁ, Dominika
The aim of this bachelor's thesis was to measure the outflow of water from a small catchment area, which was located in the upper section of the Bedřichovské brook. For the upper section, I wanted to find out what is the specific outflow of water in my monitored basin and how the basin responds with its water outflow to precipitation. To know how a specific runoff responds to precipitation, I first had to compile a consumption curve. The consumption curve showed the dependence of the water flow in the watercourse on the state of the water. I compiled it by measuring the water levels in a watercourse and calculating the relationship between these water levels and the measured water flow at certain water levels. I measured the flow at four water levels using a hydrometric propeller, the water level was recorded by an automatic meter at ten-minute intervals. I found the specific runoff by dividing the flow by the area of the basin. For a specific runoff, I found out how it will rise in short-term intense precipitation and in long-term precipitation. Precipitation was measured using a shuttle tilt flow meter throughout the month of June. I have found that how the specific runoff rises during precipitation is affected by both the length and intensity of precipitation and the vegetation around the basin.
