Simulated coastal fine-grained sediment plumes from beach nourishment near Santa Barbara, California

A coupled hydrodynamic and sediment transport model was developed to simulate the dispersal of fine-grained sediment from beach nourishment projects near Santa Barbara, California. The model simulations were used to quantify the size and extent of sediment plumes resulting from nourishment projects and evaluate the potential impacts of beneficial use of fluvial sediment captured in upland flood control facilities on coastal environments. The model data produced using the provided input files in this data release are analyzed along with satellite remote sensing observations of sediment plumes in the area to inform efficient sediment management strategies in Warrick and others (2025).
