sidescansonar
|
|
bathymetry
|
|
grab
|
|
|
Purpose
|
|
from the towed sidescan sonar, how sand
|
|
is redistributed in channel from last survey;
|
|
from the rotating sidescan sonar, tracking dune migration as indication of
|
|
bed load transport rate;
|
|
studying sed. structures of the predam flood deposits and to compare grainsize
|
|
evolution with grainsize evolution from the 1996 flood;
|
|
to monitor sediment along the river corridor;
|
|
to compare past side scanning sonar surveys with the present by looking at
|
|
changes along the river corridor
|
|
|
Information to be Derived
|
|
distribution of sediment along 17 pools of the corridor; bedform migration information along selected pools; information about primary sedimentary structures deposited during experimental flow event
|
|
|
Summary
|
|
sampling and sidesan sonar

Got Help?
|
For R-1-97-GC, we would appreciate any information on -- contract, days at sea, dive count, funding, kms of navigation, NGDC Info, organization, owner, ports, project number, publications, scanned materials, seismic description, station count, station description, submersible, tabulated info.
