The purpose of this research is to model the relationship between the amount of sediment production using MPSIAC experimental model factors and suspended sediment load using geomorphic parameters and their relationship with sedimentation in the watershed. By a simple random method, the basin of Mehran city with four specific sub-basins and equipped with a hydrometric station was selected from the southern basins of Ilam province. In order to analyze the relationship between MPSIAC model factors and geomorphic variables with the sediment of each sub-basin, statistical multiple regression method was used. According to the results of the experimental model, the amount of annual sediment in the sub-basins of Mehran city, Tang Bajak, Asan and Gonbad was estimated as 19.4, 16.8, 2.7, 12.14 and in the whole basin as 15.8 tons per hectare per year. The results of investigating the relationship between factors in sediment production and geomorphic variables in the sediment load of sub-basins showed that the amount of sediment production had a positive correlation with geological factors, land use, current erosion status, river erosion and basin topography and was significant at the 0.001 level. Is. The amount of suspended sediment load has a positive correlation with the slope index, roundness coefficient, rainfall, roughness and basin area and it is significant at the level of 0.001, and the amount of annual suspended sediment load in the sub-basins of Mehran city, Teng Bajak, Asan and Gonbad respectively is 2 It was estimated 16.5, 14.5, 11.6 and 12.4 tons per hectare per year. Principal component analysis and cluster analysis were used to influence the factors and variables on the sedimentation rate of sub-basins. The results showed that the percentage of variance explained by basin use explained 25% of the variance of all research variables and in total three factors of basin use, current erosion status, geology and two parameters of roundness coefficient and slope coefficient were able to account for 86% of the total variance. Explain the research variables. Finally, although the combined model of this research considers many factors and variables related to the amount of sediment production and sediment load, it has more significant and accurate statistical results in the watershed system.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;br&gt;
