METHOD FOR DETERMINING THALWEG IN AGRARIAN LANDSCAPES OF SLOPE LANDS IN FIELD CONDITIONS

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to agriculture, particularly, to methods for studying water erosion, and can be used in soil science, land reclamation and environmental engineering. The method for determining thalweg in agrarian landscapes of slope lands in field conditions includes application of a technical tool for profiling the daylight surface, wherein the profile of the daylight surface of the soil is measured along the circumference. The direction of the slope and the lowered sections are therein determined by the profile of the scanned circumference defining the upper cell on the studied slope in the polar coordinate system. The location of the thalweg is established, and the lower point of the profile will be located on the thalweg and constitute the point of contact with the next circular cell located below the studied slope, where the profile of the daylight surface of the soil is also measured and the location of the thalweg and the lower point are determined for said next cell.;EFFECT: increased accuracy of determining thalweg in agrarian landscapes of slope lands in field conditions.;1 cl, 1 dwg
