Eolian landforms evolutions at the right bank of the Amu-Darya River and problems of the sands siabilisation

Abstract

Wind erosion processes in the region under study are favoured by a complicated wind regime, low quantity of precipitations, and predominance of loose sands. Measurements showed the sand landforms migrate mostly southward, some seasonal migration westward and eastward were also observed. Sand surf ace consolidation was attempted using water solution of sulphate-alcohol distillery refuse with addition of suspension polyvinylacetat. The tixativc expenditure is about 2 l per sq. m. Wind-blown sands may be also fixed by Caligorzurn aphyllum or C. junceum.
