An updated “Service Pack” Beta Release of WaterCAST has been created. This Beta Release (version 1.0.2) will replace the Beta Release (version 1.0.0) that was released in November 2008. Beta Version 1.0.2 will rectify several bugs and minor annoyances that were identified in the previous Beta release:

Some users have experienced problems with setting up and running WaterCAST models and have been getting an “out of memory” error with WaterCAST Beta Version 1.0.0. This has occurred for some users that have models with a large number of functional units, subcatchments and/or constituents. The error does not occur with relatively small sized projects, which have a smaller number of subcatchments and functional units (such as those included as tutorials with the WaterCAST manual). Version 1.0.2b allows WaterCAST to use the modeller’s hard drive as temporary storage for time series data, which will prevent an overflow of the RAM accessible to WaterCAST on your computer.

A bug was fixed that ensure that the Raster2Regions process completes before enabling the “Next” button at the appropriate step in the Wizard. In some circumstances, this bug would cause WaterCAST v1.0.0b to crash if the user clicked on the next button before the Raster2Regions process had been completed.

A bug in the pre-processor that allows the importation of ASCII grids of SILO data into the model is fixed. The pre-processor in WaterCAST v1.0.0b had previously incorrectly calculated average subcatchment rainfalls from the SILO grids for some projections of the subcatchment extents.

Release notes for WaterCAST 1.0

Version 1.0 has been launched under the WaterCAST banner, building upon and refining the current E2 modelling framework, with the following features:

• Improved data management including:
  • Better handling of large scenarios (large # of catchments, long simulation periods)
  • Faster saving, loading and copying of projects and scenarios
• Improved reporting and visualisation capabilities, including:
  • Inclusion of the ?Contributor? plugin ? a reporting tool for the viewing the contributions of a particular constituent from different areas of the catchment
  • New Graph window for displaying model/scenario statistics
  • New recording infrastructure and new visualisation of model outputs
    • New Project Explorer and Recording Manager
    • Greater detail of recording options, such as the recording of totals at the FU level
    • Retention of recorded parameters set so that each time a project is loaded the parameters of interest are recorded automatically
• inclusion of the Sacramento rainfall-runoff model
• Increased data analysis and manipulation capabilities, including terrain analysis and the AsciiGrid tool, which provides a mechanism for rapidly and easily importing daily rainfall or Potential Evapotranspiration (PET) data. It is particularly suitable for very large catchments (e.g. 50,000+ km2)
• Improved input configuration of ?E2 storage? link model
• New filtering tool that allows batch application of parameters to ?region? maps
• Speed improvements to new scenario wizard
• Greater customisation possibilities:
  • "Options..." - Allows the user to set some default colours and adjust the compression level when loading and saving project files.
  • "Unit Preference?" - Allows the user to set the global unit preferences.


• SimHyd Bug Fix: There was an issue in the impervious area of the SimHyd model. It occurred only when the impervious area was activated (i.e. perviousFraction not equal to 1). Therefore, peak flows were significantly underestimated.
