Методика гидравлического исследования противоэрозионного покрытия геомата с грунтовым заполнителем и посевом многолетних трав

Abstract

The purpose of this study was to study the options for using a geomat with vegetation, namely the selection and selection of a mixture of herbs for the formation of herbage in the cover structure and the development of a hydraulic study technique. This article describes the study, which was aimed at studying the features of the formation of herbage of different grass seeds in the structure of the geomat. The features of the grass stand formation were studied and the most suitable grass variety for its use as part of a coating consisting of a geomat was determined. The results of these studies are necessary for the further application of a coating consisting of a geomat filled with soil with sowing of perennial grasses, as well as for determining its hydraulic characteristics, such as the roughness coefficient. An experimental setup for studying the hydraulic characteristics of an anti-erosion coating, a geomat with vegetation, is considered. A technique is described for determining the hydraulic characteristics with the refinement of the roughness coefficient of an anti-erosion coating consisting of a geomat filled with soil with sowing of perennial grasses. The use of this coating will give the slope of the soil structure a natural look without loss of protective properties. Also, thanks to the sowing of perennial grasses, the use of this coating will increase the environmental performance of the structure.
