Classification diagram for the observations from the Vellar estuary shown in Figure 13.4. Numbers in brackets indicate the amount of river discharge into the estuary in m3 s-1. ΔS: diference bottom salinity - surface salinity; So: ocean salinity; us: mean surface velocity; uf: freshwater velocity.
Background colour in the diagram indicates roughly the areas occupied by different estuary classes in the classification diagram discussed in chapter 12.
