Figure 10. Flow decomposition at the apex site. (a) Location of AD2CP-2 and the direction of primary (\(V_{P}\)) and secondary velocity (\(V_{S}\)). (b) Time series of \(V_{P}\) and \(V_{S}\) during high-amplitude tide (HAT ) and Low-amplitude tide (LAT ). (c,d,e,f) Vertical distribution of \(V_{P}\) magnitude with overimposed\(V_{S}\) vectors computed, at 5-minute intervals, 15 minutes before and after the bankfull stage in the HAT and LAT cycle.\(V_{s}\) are directed toward the inner and outer bank when pointing to the left- and right-hand sides of the figure, respectively.
