In this video, we present the results of a high-fidelity numerical simulation using high-performance computing to tackle one of the most important societal challenges: infrastructure stability. The numerical study was conducted to investigate the interaction of highly turbulent flow, riverbed, and bridge infrastructures in the Feather River, Northern California.  The simulation results show that the high-velocity water flow can undermine the bridge foundation by creating a scour hole of about 20 ft deep.
