(w:d) Figure 21: Distance (metres) from mouth of Glyde River versus width-depth ratio. The graphs (Figures 19 to 21) indicate a zone along the estuary where things change. This zone seems to be at the end of the exposed coastal floodplain section. There are also zones where the cross sections are very shallow and coincide with the change in channel properties. This indicates that there may have been some internal barriers in the system and these barriers may now be eroding. A model was developed to reproduce the tidal processes in the estuary resulting from dry season and wet season flood conditions. The dry season modelling results for tide gauge G8250007 located upstream of the mouth of the Glyde are given in Figures 22 and 23. m odelled elevation -4.0 -3.0 -2.0 -1.0 0.0 1.0 2.0 3.0 01 08 15 22 29 05 12 day O ctober 2000 el ev ati on Figure 22: Modelled dry season tide height at G8250007
