Description :
The AA. investigated the partitioning of Cs 137 in wind-eroded sediments and with soil surface samples sieved into contiguous ranges of particle sizes. They also compared the Cs 137 activities and stratification of several adjacent soils with known wind erosion and deposition histories. Finally, they tested Cs-based soil loss models with measured data from sites with document histories. Good agreement between model estimations and measured data indicated that Cs 137 models developed to estimate soil redistribution by water were also applicable to soil redistribution by wind provided that the models contained an appropriate particle size correction parameter.
