2016 Taylor & Francis Group, London. In the present study, sediment transport models have been implemented in the CFD solver FANS3D to simulate scour infilling process around a circular pier. FANS3D uses the finite-analytic method, which incorporates the analytic solution of the differential equation in its linearized form in the respective small subdomain. The Reynolds-Averaged Navier-Stokes equations are solved in general curvilinear coordinate system. The Chimera overset grid technique is utilized to simulate flows in a multi-block domain. This paper presents the time development of the scour hole and the infilling process due to bed load transport of non-cohesive sediment under the three flow conditions: flood, normal, and flood-tonormal transitional. The effect of the size of the sediment particle is also discussed.
