An advection-diffusion model is proposed to simulate large wood transport during high flows. The mathematical derived from the mass balance, taking into consideration both concentration and log orientation, which affects and, most importantly, accumulation. Focusing on transport, equation implemented in a hydrodynamic provide one-way coupled solution of flow floating mass. tested series flume e...

The predictive capability of two way–coupled point-particle Euler–Lagrange model in accurately capturing particle-flow interactions under grid refinement, wherein the particle size can be comparable to size, is systematically evaluated. Two situations are considered, (i) uniform flow over a stationary particle, and (ii) decaying isotropic turbulence laden with Kolmogorov-scale particles. Partic...
