Abstract

In this study, to evaluate the sediment yield of different geomorphic facies in Aran region, the Wind erosion meter and IRIFR model were used. The results of Wind erosion meter showed that the most speed of threshold in natural condition is belonging to hard crust and dried clay plain with a speed of 13m/s, then puffy and clay-agricultural lands with a speed of 12 m/s, and the lowest threshold speed is 6. 5 m/s related to fine-grained loamy-sandy soils of pediment that due to lack of the adhesion, flat, and smooth surface and wind shear impact and blown with wind. The results of Wind erosion intensity with Wind erosion meter also showed that the clay plains and puffy lands facies are most stable with sediment of 0 to 175. 2 tone/km 2 / yr which sorted in erosion class I, and sand sheet with the graveled covered, clay plain and sand dunes are the most sensitive facies, with 5450. 09 to 5517. 04 tone/km2/ yr sediment equivalent classified in erosion class IV. While the results of the IRIFR model showed that the most stable facies are agricultural lands with 415. 1 ton/km2/yr sediment erosion that classified in the erosion class II and facies sand sheet and sand dune the most sensitive facies, that with 1168. 6 ton/km2/ yr sediment equivalent classified in erosion class IV. According to statistics obtained from the two models, it is concluded that except to the puffy land and clay plain there was not significant differences among the rest of facies.
