FIELD: physics. ^ SUBSTANCE: photographic images of the eroded soil are taken using a cord (belt) and/or graduated scale. The obtained image is then displayed on a computer screen, where the profile of the eroded part is selected on the horizontal level and contours of the surface of the eroded soil. Further, the area of the eroded part is determined and the volume of soil lost due to water erosion is then calculated. ^ EFFECT: method for rapid determination of soil loss after torrential rain or snow melt, where there is fast photographic capture of the profile of the eroded soil with high speed of measuring soil loss, with low cost and high accuracy compared to existing methods. ^ 2 cl, 4 dwg |
