Overview

Computational modeling study demonstrates accurate prediction of large wood transport and logjam formation around hydraulic structures, highlighting a cost-effective tool for flood mitigation design.

Key Points

To develop and validate a coupled numerical framework capable of simulating the dynamic transport of large wood logs and their interactions with flood control structures.
Coupled Eulerian Computational Fluid Dynamics (CFD) for water hydrodynamics with a Lagrangian Discrete Element Method (DEM) for log kinematics and multi-body interactions.
Validated the numerical framework against experimental data from a 1:16 scale physical model of the Springbank off-stream storage reservoir structure on the Elbow River in Canada.
The coupled CFD-DEM model successfully predicted individual log trajectories and the formation of wood jams at hydraulic barriers across tested structural configurations.
The simulation framework enabled testing of hazardous flood scenarios that are impractical or cost-prohibitive to evaluate in physical laboratory experiments.
