Variation of the three non-dimensional parameters P (red contours in right diagram), Fm (green contours in right diagram) and ν (blue contours in left diagram) as functions of the observable quantities ΔS / S0 and us / uf. See text for explanation of symbols. Letters refer to the classification of positive estuaries discussed in Chapter 11: W = salt wedge, H = highly stratified, S = slightly stratified, M = vertically mixed. Adapted from Hansen and Rattray (1966).
