two-phase Eulerian equations for sediment transport (see the user document)
the typical length scale can be on the order of 0.1~100 m, and the resolution in the vertical can be on the order of grain size, while the horizontal grid resolution can be relaxed appropriately .
alpha: sediment concentration
Ua: sediment velocity
Ub: fluid velocity
p: fluid pressure
Theta: granular temperature
k: fluid kinetic energy
epsilon/omega: fluid turbulent dissipation
sediment transport drive by turbulent/laminar flows
The typical time scale is on the order of 100 second, and the time step should satisfy the Courant number (<0.3)

A three-dimensional two-phase flow solver, SedFoam-2.0, is presented for sediment transport applications. The solver is extended upon twoPhaseEulerSedFoam (https://csdms.colorado.edu/wiki/Model:TwoPhaseEulerSedFoam). In this approach the sediment phase is modeled as a continuum, and constitutive laws have to be prescribed for the sediment stresses. In the proposed solver, two different inter-granular stress models are implemented: the kinetic theory of granular flows and the dense granular flow rheology μ(I). For the fluid stress, laminar or turbulent flow regimes can be simulated and three different turbulence models are available for sediment transport: a simple mixing length model (one-dimensional configuration only), a k-ϵ and a k-ω model. The numerical implementation is first demonstrated by two validation test cases, sedimentation of suspended particles and laminar bed-load. Two applications are then investigated to illustrate the capabilities of SedFoam-2.0 to deal with complex turbulent sediment transport problems, such as sheet flow and scouring, with different combinations of inter-granular stress and turbulence models.
