Abstract: Sediment transport is an essential aspect of river engineering that affects channel stability, flood risks, and hydraulic structures. This study focuses on analyzing sediment behavior in the Mandavya River using HEC-RAS modelling software. The objective is to evaluate sediment movement, erosion, and deposition under different flow conditions by incorporating river geometry, flow data, and sediment characteristics into the model. Both steady and unsteady flow simulations were carried out, and various sediment transport functions were tested to determine their suitability. The analysis highlights sediment load distribution, bed level changes, and areas prone to aggradation and degradation. Results indicate that sediment transport is highly influenced by discharge variations and channel slope. The model successfully identifies critical zones of erosion and deposition, supporting effective river management and flood mitigation planning. Overall, the study demonstrates that HEC-RAS is a reliable tool and provides a strong scientific basis for sustainable river basin management and infrastructure development.
