The aim of this study is to compare water and wind erosion functions in land degradation of Dasht-e-Jeihoon using PSIAC and IRIFR.EA models and the source studying of aeolian sediments in geomorphologic facieses as homogeneous units. The results indicate that in Dasht-e-Jeihoon, water erosion has been transferred fine and coarse grained sediments to the center of plain. In fact, in this region wind erosion fulfills the effect of water erosion in center of the plain. Erosion estimation shows that 50.3 percent of the region includes the mountain facieses )erosional or bare pediment (which water erosion is moderate to high, have minute to low wind erosion and 49.7 percent of the region includes the facieses of Epandage and covered pediment which water erosion is low while wind erosion has moderate to high effects. Water erosion not only results 39.7 percent of the Dashte-Jeihoon sedimentation, but also it has a significant role to supply erodible particles in downstream of the region.  Observations and the results showed that for estimating the erosion in dry areas such as Dashte-Jeihoon, we need to use water and wind erosion estimator models as supplements. %U https://jrwm.ut.ac.ir/article_32043_76bbe8f62cad524918ae47e9b8e31bff.pdf
