Protection of catchment plots and installations from sand drift at takyrs

Abstract

At sand deserts of Central Asia takyrs are not subjected to sand drift under natural conditions due to peculiar aerodynamics. If the takyr surface is broken and built-up, the equilibrium is upset which results in barkihans transgressing the takyr and sand accumulation on .the lee side of obstacles. To protect the takyr surface and constructions certain measures are necessary on fixing sands at the windward side of protected objects.
