Suspended-sediment concentrations

Contour plots of SSC for the spatial surveys during trade-wind conditions on the reef flat. (a) SSC from the low tide survey. The highest SSC (60e70 mg/l) were located in a nearshore band, and east of the fish ponds and Kaunakakai wharf. (b) SSC from the high tide surveys. SSC in excess of 80 mg/l are seen in a nearshore band and east of the fish ponds and wharf. The SSC rapidly decreases with distance offshore from 130 mg/l to <5 mg/l, exhibiting the constraint of SSC to the inner-reef flat.
