     an integrated 2dh numerical model based on eulerian approach including hydrodynamic, suspended sediment transport, oil transport and combined oil slick-sediment transport module has been developed and validated against laboratory measured values. fvm method and adi (alternating direction implicit) scheme have been employed for disceritization and solving governing equations. the second order lax-wendrof and second order central difference schemes have been used for advective and diffusive terms respectively. multiphase oil spill model (mosm) approach has been taken to simulate oil slick and flow interaction. all three modules of the numerical model have been validated against experimental data. the model capability for simulation, oil spill and suspended sediment transport, has been examined and the predictions show reasonable accuracy compared with analytical solutions and measured values reported in the literature. as an application the effect of oil in suspended sediment transport has been investigated for alternative concentrations which show increase of concentration of suspended sediment with the increase of oil entered in water column.
