Abstract

 The purpose of this study was is to use and explain the application and importance of multi-time images (time repetition) of Landsat Satellites to highlight changes in the area (bed and shores) of Shirin Darreh River, as well as evaluating river geomorphology variations with respect to the extent of bed development. General and active river types and river deformation during the periods 1995 to 2019 was studied over five evaluation periods including 1995 to 2005 (first period), 2005 to 2010 (second period), 2010 to 2015 (third period), . The period of From 2015  to 2017  was considered as the fourth period and the period from 2017 to 2019  was recorded for the fifth period. Two empirical EPM and MPSIAC erosion and sedimentation models were employed for river variation prediction. EPM model was based on the principle of scoring two main variables including the intensity and extent of erosion and sedimentation was examined with respect to the erosion-susceptibility of the catchment. The MPSIAC model was used to determine the impact and role of 9 important and effective factors in soil erosion and sedimentation of the catchment, estimated sedimentation and erosion status were obtained. According to the results, it was found that Shirin Darreh catchment area has a total sedimentation of 831,340 cubic meters per year and sedimentation was equivalent to 217909.94 tons per year estimated by the EPM model, while a total values ​​of 750.750 cubic meters per year sedimentation equivalent to 5/5. 658509 tons per year at a surface area with a sediment delivery rate of 38.02 was obtained by the MPSIAC model. Also, by validating the experimental models, it was found that the results of the MPSIAC model were more accurate than the EPM in the study area.
