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
