• Updated the software to support newer versions of Windows.

NOTE: please read carefully the "known issues" section

Changes:

• The main change is an updated documentation. The user guide is in PDF format.
• The product includes a component checking the availability online of newer versions of the RRL on the Toolkit web site at program startup.
• No expiry date.
• Some of the dates in the sample data (Bass and Jardine rivers), which were previously unknown, have been tracked and corrected.
• Some time series format have been removed from the list for saving monthly data, since they could not handle that time step anyway.
• Following a Toolkit Steering Group, the comma separated values file extension is now '.cdt'. The '.csv' extension was too generic and leading some users into thinking that any such file produced by Excel would be readable.
• Incorrect or unrecognised file formats are better handled and the software tries to give users detailed information about why data failed to load
• Better detection of changes in a project, to signal to the user the necessity to save a project prior to creating a new project, or opening another one. Note that changing the model via the list box will still override the previous settings.
• A powerpoint used at the Catchment Modelling School 2004 is included in the installer as training material

Known issues:

• A copy-paste of large grids of time series will apparently hang. The problem at that stage seems to be in the standard Microsoft grid component, though the problem is hard to investigate. Please use the facility of the Time Series Viewer instead if you want to save time series from a calibration run

• NOTICE: 7 September 2004.

  Errors have been reported in the Tank model of the Rainfall Runoff Library. One is easily fixed, but the other has been investigated and traced to an error in the original code provided to us. This error stems from ambiguity in the interpretation of the original reference; (Sugawara, M. (1995). Tank model in Computer models of watershed hydrology, Water Resources Publications, 164-214).

  We *recommend* that Tank not be used until further notice. Resolution of the error will require us to contact the source code developer and undertake additional testing. This may take some time. We apologise for any inconvenience this may cause.

  Please note, these errors in Tank do not impact on other models within RRL.

Changes:

• Expiry date extended to 01/03/2005.
• The product includes a component checking the availability online of newer versions of the RRL on the Toolkit web site at program startup
• Fix: cases trying to write a data or project file where users do not have write access is handled more gracefully
• Fix: Changing from a log-log Scatter plot to visualising time series could lead to unexpected values on the x-axis in some circumstances
• The software remembers the last directory paths where data and projects were saved, independantly one from another. Last directory paths are also remembered from session to session.
• Additional sample project for each model

The activation key for the current version 1.0.3b is 95e4a1da027f. Current users of version 1.0.3b will be able to continue using this version without having to download and reinstall the upcoming 1.0.4b. No major bug has been reported, so the key is made available to existing users for convenience.

This release is expected to be the last beta release. Most effort will now be on finalising the documentation - please send comments to the e-group

Changes:

• Expiry date 15/06/2004. Please subscribe to the RRL mailing list since the next release will be announced via this list.
• Reviewed the labels of the model and calibration tools
• Calibration tools parameters tool tip pop-up with summary information
• Improved the sampling algorithm for calibration on the duration curve, which was not giving good enough results on very small data sets
• AWBM auto-calibration tool made to match existing implementation. It was searching on larger parameter intervals than original implementation.
• Calibration process is run in its own thread so as not to preclude the responsiveness of the user interface
• The scatter plot of monthly runoff was showing the entries of the warmup period. The Nash-Sutcliffe coefficient was however correct.
• Removed non-relevant output file formats for saving recorded state variables

Changes:

• Expiry date of beta version extended to 15/04/2004
• Configuration settings saved to the registry, not through a file in Program Files folders
• Fixed: display algorithm prevents the dimming that occured on duration curves of a long time series
• Fixed: Calibration on the duration curve with SimHyd could lead to an unhanldled exception
• Fixed: Project files referencing data files on a network drive could not be reloaded in some circumstances
• Added CSV as an output file format
• Removed non-relevant output file formats
• Added the relative and absolute runoff depth difference in the data statistics.
• Fixed: the data scaling entries were lost if the Enter key was not pressed or the up-down arrows were not used

• Extended the evaluation period.
• Fixed the 'NaN' in monthly verification period.

Acknowledgements
Contributions to RRL came from a number of members and associates of the CRC for Catchment Hydrology. In particular we wish to thank Geoff Podger (Department of Infrastructure, Planning and Natural Resources) for Sacramento model source code, support and examples; Dr. Walter Boughton (University of Queensland) for AWBM source code, support and examples and Dr. Francis Chiew (The University of Melbourne) for SimHyd source code, support and examples, Nicholas Murray (CSIRO Land and Water) for assistance with standards and documentation. David Perry (Communication and Adoption Program Leader, CRC for Catchment Hydrology) coordinated the release of RRL on the Toolkit web site. Susan Daly (CRC for Catchment Hydrology) for the graphic design and production of model schematics.

Development History
RRL has been in development as part of the CRC for Catchment Hydrology’s Predicting Catchment Behaviour Program since July 2002. The RRL was developed as a useful tool for hydrologists but also to test how easy it was to develop models written in different languages within TIME and .NET. It has also proved useful in setting standards and protocols for applications developed within the CRC for Catchment Hydrology.

Future development
There is no future development planned for RRL after the release of version 1 in mid 2004. It is hoped however, as more people use the RRL they may suggest other models that should be included or may want to include their own models.
