Estimation of suspended sediment load is one of the most important factors in the hydraulic, morphological and hydraulic behavior of river sediments and the basis of proper management of water and soil resources in Drainage basin. Estimation of the total suspended load of the river is often possible with the data measured in hydrometric stations from establishing the relationships of sediment measurement curves using conventional methods. In this paper, the amount of sediment estimation in Damavand Drainage basin has been estimated through statistics recorded in Mamlu hydrometric station. The main rivers of Damavand Drainage basin are Damavand and Siahroud rivers. Damavand river which flows from east to west of the basin and while passing through Damavand city, Tarroud, Arab chenarha, Gilavand, Hesare paeen, Mara, Kajan, Tamisan, Zareh Dar and Siah Sang, after 48 km, finally in Yurd Shah It joins Jajroud river. For this purpose, these statistics (related to Damavand Drainage basin) were received from Tamab Company. According to the study, the average annual bed load in Damavand Drainage basin is 46395.332 tons, the total discharge of sedimentary materials is 2783.2192 tons and the specific sediment production of the basin is on average 3665.12 tons per square kilometer. The results of this study show that Karaj Formation, due to its area in Damavand Drainage basin, has the largest share in sediment production.
