Investigation of Salt and Dust Transfer Processes Using Passive Dust Traps in Uzbekistan

Abstract

The article discusses some experimental results obtained in the framework of the international project CALTER to study the eolian erosion in Uzbekistan in the period 2006-2010. Network monitoring has been organized for research, which included sampling points of dry atmospheric fall-out (DAF), located in different physical and geographical zones and characterized by different types of soil and wind load. As an indicator of the intensity of eolian erosion process, the flux density of dry atmospheric deposition has been selected (monthly, seasonal, annual and perennial), the particulate composition of the surface layer of soil and dry atmospheric fall-out at points of monitoring had been investigated. The influence of some meteorological parameters on the quantitative characteristics of DAF has been investigated. The obtained values of the flux density of dry deposition are comparable to characteristics traditionally used to determine the intensity of wind erosion. The proposed method is cheap and easy to use, allows covering large areas, and exploring the features of salt and dust transfer processes.
