This research investigates the influence of thermodiffusion (Soret effect) and diffusion-thermo (Dufour effect) on transient Magneto-Hydro-Dynamic (MHD) free convective flow adjacent to a heated, inclined plate within a porous medium. The analysis incorporates thermal radiation as a key heat transfer mechanism, accounting for time-dependent variations in both velocity and temperature distributions. The porous structure introduces hydraulic resistance, altering fluid motion and thermal transport properties, while the plate's inclination modifies buoyancy-driven convection patterns. The applied magnetic field further complicates the dynamics through Lorentz force interactions. By addressing the coupled Soret and Dufour effects— frequently overlooked in basic models—the study enhances understanding of multispecies heat and mass transfer. The governing nonlinear partial differential equations are solved numerically via the finite difference method.Graphical results demonstrate how critical parameters affect velocity, temperature, and concentration profiles. This computational framework elucidates the complex interdependencies among electromagnetic, thermal, and hydrodynamic phenomena in porous media flows. Major Findings: Soret and Dufour effects significantly influence MHD free convection near an inclined plate in a porous medium. Radiation, magnetic field, and inclination modify flow and heat transfer. Numerical results show complex velocity, temperature, and concentration profiles.
