Rivers are easily accessible resources of water for miscellaneous uses but the erosion and sedimentation inrivers are unique and great deal of importance. The analysis of flow and sediment in riverunder different conditions is a base for rivers’ behavior and decision making on engineering aspects. Kunar River is an important river of Afghanistan, has considerable interest because of strategic and environmental condition regarding water resources project planning, agriculture, forests, hydropower and industrial scope. This study is carried out to simulate the process of erosion and sedimentation using HEC-RAS model to assess hydraulic parameters and sedimentation processesin 250 Km stretch of Kunar Riverfrom Nari district of Kunar province to Pul-e-Kama of Nangarhar Province. The model was calibrated manually for hydraulic parameters of river flow and then sediment transport model was simulated. The changes in transverse and longitudinal profile, velocity and shear stress variation along the river, mass inflow and outflow, bed level change of river and suspended sediment concentration is studied for the modeled length.The sediment transport from river tributaries and gullies joining the river from two sides of narrow valley isalso assessed.
