Abstract
This study represents the result of flow simulation in the Jamuna River using one dimensional HEC-RAS model. The Water bed profile is different in different cross section of a river. This study determines the differences in water level elevation for different years and determines the changes in bed profile in different cross-section of the river Jamuna. In this study, cross section of river, river depth, wetted perimeter, water depth in different cross sections were used to simulate the flow using one dimensional HEC-RAS. From the result of simulation, we can assume the increase or decrease in the bed profile for future years
