This asset relates to the Richmond River and consists of the outputs from hydrodynamic modelling undertaken by the University of New South Wales Water Research Laboratory (WRL) to investigate changes in salinity dynamics under sea level rise and possible changes to catchment hydrology.
Three different sea level scenarios were modelled, a present-day sea level, a sea level increase of 0.20 m and an increase of 0.55 m. A series of hydrological sensitivity tests were also run to explore system sensitivity to changes in flow and changes in freshwater flushing events. This asset comprises the full technical report written by WRL, timeseries data for each model scenario run, and all the run files required to re-run the model using RMA software.

Note: If you would like to ask a question, make any suggestions, or tell us how you are using this dataset, please visit the NSW Water Hub which has an online forum you can join.
