Sediment is one of the major contributing factors that affect the river morphology of the United States. During the construction of hydraulic structures like a dam, irrigation channel, or even to utilize the stream for navigation purpose, one of the major concerns for the design engineer would be the characteristics of sediment transported within reach. Maumee River serves for navigation purpose, and the riverbed aggradation resulting in shallow depth may affect its use. Thus, the study of sediment flow and the river bed characteristics is essential to mitigate the problems arising due to the changes in river morphology. The river reach is selected based upon available gauged station and proximity of the settlement. In this study, the Hydrologic Engineering Center's-River Analysis System (HEC-RAS) was used to develop a hydraulic analysis of the sediment transport model. The geometric data were generated from 10-meter x 10-meter resolution digital elevation model using HEC-GeoRAS extension in ArcGIS. Calibration and validation of this model were done by applying various sediment transport functions and Manning's roughness coefficient. The model output indicates the bed change pattern as well as the parts of a river reach that conform to erosion or deposition. The output of the model combined with local knowledge can help to attenuate the problem arising due to the sediment.
