This study investigates sediment transport dynamics in the Dognecea River, located in Caraș Severin County using MIKE 11. Numerical simulations were conducted to analyze sediment deposition, erosion patterns, and structural interactions. The sediment transport model considers multiple factors, including riverbed sediment characteristics, hydrodynamic conditions, and structural modifications. The sediment transport model has several applications, with variations in parameters such as study objectives, allocated resources, time scale, space, context of the study team, required accuracy, etc. The characteristics of the sediments in the riverbed are a necessary component to know for modeling sediment transport. It is proposed to collect additional sediment samples from the sediments of the layer. The samples obtained will be analyzed according to the size of the particles in the bed. To address sediment transport issues in the Dognecea River, advanced water flow modeling programs are used. Numerical modeling was performed using the MIKE11 software, incorporating hydraulic flow simulations to analyze sediment transport dynamics. Transport models can be used in the case of small alluvium, such as mud or clay, to non-cohesive deposited alluvium, such as boulders, small ballast and sand, but also mixed sediments. MIKE 11 provides several options for modeling the movement over time of alluvial transport, as well as structural changes in the riverbed. The results provide insights into alluvial transport behavior and offer solutions for mitigating sediment-related challenges such as riverbed clogging and erosion control. The findings demonstrate the effectiveness of MIKE11 in modeling hydraulic and sediment transport processes, making it a valuable tool for water resource management and flood risk mitigation.
