Abstract: Soil erosion is one of the most significant forms of environmental problems in the world. PSIAC and MPSIAC models are more applied methods to assess sediment yield and erosion. In this research, these models used to assess annual average sediment yield and annual erosion to Bishezard watershed. Results showed, based on MPSIAC model 92.64% and 5.88% of study area were in the slight and moderate sedimentation classes, respectively. Based on PSIAC model, 75.11% and 11.1% of study area were in the slight and moderate sedimentation classes, respectively. The total sediment yield in the study area based on MPSIAC and PSIAC models 1,439.27 and 1,434.44 (m³/km²year) were calculated, respectively. According to sensitivity analysis, in MPSIAC, topography and runoff erosion factors (with Pearson correlation 0.68 and 0.51) and in PSIAC land use and land cover factors (with Pearson correlation 0.73 and 0.67) were the most sensitive factors.
