Abstract

The aim of this study was to quantify windblown mass transport on a sandy soil in Central Patagonia. Aeolian mass fluxes were measured in the valley of Sarmiento (Chubut province, Argentina) using 2 saltiphones and 24 Modified Wilson and Cooke (MWAC) sediment catchers. Nine windstorms were recorded throughout the experimental period. An artificial windbreak reduced the soil loss by 51% on average in a cherry orchard. Measured maximum mass transport values were used to fit 5 sediment transport equations in order to select the best equation to integrate into a GIS-based wind erosion prediction system. It is shown that overgrazing and agricultural activities increase wind erosion risk in Patagonia
