Summary

The data for this mater thesis were collected in Vysoké Pole. In this village there is situated a new built EnviCentrum. Background and conditions for deployment of dataloggers could be created thanks to the cooperation between EnviCentum Vysoké Pole and Department of Geoinformatics in Olomouc.

This master thesis determines two main aims. The first one is associated with monitoring. Two types of data were collected in Vysoké Pole. The first one was meteorological data and the second one was hydrological data. Meteorological data were measured continually with the help of dataloggers. These dataloggers were situated in four places with different vegetation conditions. Data about temperature, relative humidity and percipitation are the most important data in this thesis. Hydrological data about discharge and water stage were collected discontinuously in the observed part of a water stream. Values of discharge were collected by two different ways. The first one used canal for discharge measurements and the second one used a bin which volume is known. Monitoring is an important part of this thesis because the collected data were processed, described, graphically displayed and used in the second part of this thesis.

Data were collected from the observed part of the water stream. This data became the basis of creating longitudinal stream profile, planimetric drawing and channel cross section in two parts of the water stream.

The observed area was decribed and a digital terrain model was constructed for better image about elevation rate.

The second part of aims was to model surface runoff in a studied microwater basin. CN-curves method was chosen to model surface runoff in this area. This method is widely used for describing surface runoff in a small water basin. Every pixel in a microwater basin was evaluated by CN-number. The surface runoff was computed for two days: 31.5. and 12.10. Very important for computation is percipitation in five days before the computed day. The difference between percipitation in these two days was 5,6 mm. The higher runoff was computed in the day with higher percipitation before this day and the higher runoff was situated in impermeable areas.

The last part of this master thesis is devoted to soil water erosion. The average soil loss from pixels was computed in three months with the help of the method called (R)USLE. The highest soil loss was computed in the pixels with steeper slope and no vegatation cover. Besides of slope the loss of soil is also determined by against-erosion stroke, eroded stroke of soil erosion, force of rainfall and vegetation cover. The last two factors didn´t have the same value in computed months.

The possibilities of obtaining and processing data from continuous and discontinuous measurements are shown in this master thesis. Measured data were combined with provided data and used for computing surface runoff and erosion.
