Plume processes, sediment dispersal, and deposition on the Eel
River shelf for a simulated flood event.
These animations were presented in
"Dispersal of flood sediment by oceanographic currents and energetic
waves"; Courtney Harris, W. Rockwell Geyer, and Rich Signell, AGU
Ocean Sciences Meeting, January 2000, San Antonio, Texas
The simulations are for a 6-day flood event, with peak discharge of
10K m3/s. Winds are strong and from the south for the first three days
and then die off for the remainder of the event.
Simulations made using ECOM-SED from Hydroqual.
Plume Dynamics
The left panel shows the freshwater plume's structure. The right panel
the amount of suspended sediment in the surface. The red arrows are
depth-averaged velocity. The big-then-small red arrow on the upper
right of the sediment-panel represents the strength and direction of
the wind stress.
Sediment Dynamics
The left panel is the near-bed suspended sediment concentration, with
contour lines ranging from 10mg/L to 10g/L. The middle panel is
depth-integrated suspended sediment with contour lines ranging from
1mm to 10cm. The right panel is depth of sediment deposition, with
contour lines ranging from 1mm to 10cm.
These are in "flc" format. See Rich Signell's guide to fli/flc if you
need help viewing them.
