The results of theoretical research on land leveling of irrigated lands

The article deals with the improvement of office work in the design of land leveling works. On the basis of field experiments, the authors obtained results on determining the number of profiles depending on the accuracy; they propose methods for calculating land leveling work with a rectangular grid for a minimum amount of earthwork, as well as hydraulically optimal slopes. The authors propose the land leveling quality coefficient depending on the quality of the field surface and the uniform distribution of soil density.
