The AUSRIVAS Macroinvertebrate Predictive Modelling software requires Internet access in order to run a model. Model data is maintained at a central site and stored on a server at this site (currently at the CRCFE University of Canberra site). When an authorised user runs AUSRIVAS, the software connects to this central server to access the latest model information, and uses this to produce an assessment of the condition of a test site.

 

 

If you do not have Internet access, you can still run the software and load previously saved data, but you wont be able to access information about the models and you wont be able to run a model.
