ABSTRACT

ABSTRACT: The estimation of erosion and sedimentation rates in a watershed has always been an interesting subject for planners and researchers in the field of erosion and sedimentation. Employing several empirical models and techniques is prevalent due to the shortage of measured and recorded data in Iran, although application of these models is not always followed by appropriate, logical, and expected results because of various reasons. The present investigation is intended to explore the condition of water erosion and production of sediments in Amameh watershed using EPM empirical method and comparing its results with the observed sedimentation data in this region. According to data intermediate analysis, compared to the observed sedimentation data, the results of estimation of sedimentation rate showed that the rate of relative error has been 117.7% in EPM empirical method.
