Sediment deposition from bouyant river plumes
ORAL
Abstract
The ground deposition patterns of sediments that are carried by a river into the ocean are studied via numerical simulation. The bouyant plume of particle-laden fresh water evolving in ambient sea water near the estuary is assumed to spread axisymmetrically. Model predictions, both for the flow field and for the sediment deposition, are derived from the shallow water approximation as well as from the boundary layer equations. Predictive capabilities of these models are assessed by comparison to results from direct numerical simulations.
