Tidal Residuals in Homogeneous Systems z δ=4L/λ > 0.6-0.7 δ=4L/λ < 0.6-0.7 Li and O’Donnell (2005, JPO, 1826)
Examples of Tidal Residuals Influenced by Bathymetry in a Short Channel OUT OUT IN St Augustine Inlet St. Augustine Inlet location and cross-section of net exchange flow pattern. Red and yellow shades indicate regions of net outflow while blue shades denote regions of inflow.
low E med E high E Ke = B/R; E = Az / (f H2) (wide) (narrow) So in order to address that question, the solution can be examined in terms of the Kelvin number (ratio of width of system vs internal Rossby radius) Three generalities may be drawn for the along-estuary flows (contours): 1) Exchange pattern depends on the width of the system: inflow occupies entire water column for low E and high Ke 2) Two-way exchange is most vigorous with moderate friction (med E) 3) Exchange pattern is independent of width of system for high E: inflow occupies the entire column high E Ke = B/R; E = Az / (f H2) (looking into the estuary; orange is inflow; white is outflow)
