VOLUMETRIC QUANTIFICATION OF SOIL EROSION AND ANALYSIS OF CHOSEN LOCALITY IN TERMS OF RUNOFF AND EROSION CONDITIONS

Popis výsledku v původním jazyce

The purpose of this paper is volumetric quantification of soil erosion using the so-called erosion bridge. For the measurement, a locality in the South Moravian Region of the Czech Republic was chosen. With the erosion bridge, we can measure erosion rills. Rill erosion is caused by concentrated water flow. It occurs when runoff water forms small channels as it concentrates down a slope. The erosion bridge is a very simple device that enables us to accurately measure the shape of the soil surface in a given place. It was designed and created at the Institute of Landscape Water Management, Faculty of Civil Engineering, Brno University of Technology. The erosion bridge consists, besides other parts, of a rectangular steel frame to which needles are attached. These needles are lowered onto the terrain, copying its profile. Using this method, we get photos of the profile of the terrain, which are subsequently evaluated using a software program and exported into a DXF file that can be opened in AutoCAD. It is then possible to calculate soil loss. This paper also deals with the analysis of the chosen locality in terms of runoff and erosion conditions. This analysis was made by using geographic information systems, mainly ArcGIS Pro software program.
