| Another useful way to take advantage of the model’s temporal and spatial resolution
was to analyse the modelled salinity predictions and examine the number of times throughout
any wet-season that any region was exposed to any low salinity events. This is also known as
Exceedence Analysis and maps regions which exceed a given threshold for a threshold duration in time.
Since runoff induces lower salinity events in the model, it was possible to convert salinity levels into concentrations of freshwater runoff as detailed in the table below. Thus a fresh water exceedance map gives locations which experience lower salinity events while the number of exceedences measured the exposure times that each location was subjected too. |
 | Table shows the amount of freshwater runoff and coastal saltwater present in the model predicted salinity distributions and what dilution factor with pure seawater each salinity represents. |
