The accurate hydrodynamic profiling of river systems is necessary to understand the dynamics of the flow,
flood risk, and sediment transport mechanisms. The study uses the Telemac-2D algorithm to simulate and analyse
two-dimensional hydrodynamic behaviour in the environment of a selected river. The model includes the velocity
regions, the height of the water surface, and the spatially distributed profiles of the shear tension, including a detailed
bathymetry, boundary position, and flow parameters. The finite element approach to Telemac-2D enables the accurate
modelling of complex geometric, meander flow, and unstable flow phenomena. Getting a high correlation and a low
error matrix, compliance and verification were done using observation discharge and water level data. Simulation
results reveal potential areas for significant flow areas, backwater effects, and erosion, and statement, providing
valuable insight to flood management, infrastructure plans, and ecological evaluation. The study underlines the
effectiveness of TELEMAC-2D as a versatile tool for hydrodynamic analysis in river systems with various
topographical and hydraulic complications.
