This asset relates to the Tweed 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.
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.
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.
