Figure 6. Relationships between depth-averaged velocity (DAV ),
water depth (Y ), and water-depth change rate
(\(\dot{Y}=\ dY/dt\)) at the four measuring stations. Columns from the
left- to the right-hand side of the figure show, respectively, results
for AD2CP-1 (seaward inflection point), AD2CP-2 (bend apex), ADCP (side
tributary confluence), and AD2CP-3 (landward inflection point). Red and
blue quadrants represent data obtained during the flood and the ebb
phase, respectively. (a, b, c, d) Water depth (\(Y\)) vs. depth-averaged
velocity (DAV ) curves for all the monitored tidal cycles. Red and
blue points denote the maximum flood and ebb DAVs of each tidal
cycle. (e, f, g, h) Water depth (\(Y\)) vs. water-depth change rate
(\(\dot{Y}\)) curves for all the monitored tidal cycles. Red and blue
points denote the maximum flood and ebb \(\dot{Y}\) of each tidal cycle.
(i, j, k, l) Depth-averaged velocity (DAV ) as a function of
water-depth change rate (\(\dot{Y}\)) for below-bankfull stages during
all the monitored tidal cycles. (m, n, o, p) Depth-averaged velocity
(DAV ) as a function of water-depth change rate (\(\dot{Y}\)) for
above-bankfull stages during all the monitored tidal cycles.
