Determination of geomats’ roughness coefficient

Abstract

The purpose of the article is to determine the geomats’ roughness coefficients applied to improve the stability of road bed embankments against washing away by surface waters. The authors describe the effect of roughness coefficients on the hydraulic resistance of water movement. The authors’ve analyzed design formulas on the bases of which the values of geomats’roughness coefficients have been experimentally gotten. There are described conditions of conducting experiment in the laboratory "Hydraulics and Engineering Hydrology" of SibADI. The issue of geomats’ application to improve the stability of road bed embankments against water erosion processes is poorly studied and requires further research
