Abstract
Reduction of soil erosion is one of the main issues of modern engineering ecology. It should be noted that this problem is caused not only by natural factors, but also by peculiarities of some irrigation methods. The article considers the issue of erosion of earthen channels of temporary irrigation network under gravity irrigation. On the temporary irrigation network of three villages in Shida Kartli region of Georgia the amount of erosion was experimentally determined and its dependence on network parameters and soil conditions was established. As a result of this work, to reduce soil erosion (scouring), it is recommended to install canals with compacted crosssection.
