Interpretive Summary:

Technical Abstract: Wind erosion and deposition results when wind moves soil from a bare susceptible surface to another location downwind. Although placement of permanent vertical references such as pins or rods has been used to measure soil redistribution, it is more commonly measured by capturing sediment moving during an event. Through the years, several sampling devices have been developed to trap sediment in transport or to measure fine dust that may linger after a wind event. Some of the devices are passive, meaning they use the force of the wind and the momentum of the sediment to fill the sampler, and some are active, meaning that a stream of air is drawn through the sampler by a vacuum source. In addition to sampling sediment in transport and suspended in the atmosphere, methods have emerged that allow estimation of redistribution rates by comparing soil borne environmental tracer content on a landscape with the tracer content of a location in which no erosion or deposition has occurred.
