FIG. 7. Circulation and momentum balances for idealized inlet at midebb: (a) velocity flux (depth-averaged velocity multiplied
by total water column) vectors interpolated onto uniform 425-m grid for clarity, (b) free-surface elevation with 1-cm contour
intervals, (c) bathymetry with 1-m contour intervals, and (d)(k) shaded contours of individual momentum flux terms (see text
for description).
