eWater is pleased to announce the latest Production Release of Source version 5.10. Key enhancements in version 5.10 include improvements to the Operations Tabular Editor, the ability to Hot Start GR4J and Sacramento rainfall-runoff models, significant enhancements to the Calibration Tool, updates to the Environmental Flow Node and Manager and additions to Scenario Input Sets to make it easier to work with large models with significant scenario modelling.
Improvements to Source
Calibration Improvements
The calibration tool has been significantly extended, you can now:
- calibrate Schematic Scenarios,
- calibrate any parameters in the model that are available through Scenario Input Sets, and
- specify relationships between meta-parameters.
This is a significant step forward for the calibration tool, it's currently called Flow Calibration Tool, however, this should be updated soon.
The Calibration tool and Bivariate stats now support multiple parameters for Objective Functions. The Square-root Daily, Exceedance, and Bias function now has three parameters, Alpha (α), Lamda (λ) and Mu (μ). Details of the implementation are here: Bivariate Statistics SRG
These can now be set in both the Calibration tool and when looking at the Bivariate stats in the Results Manager:
Ability to model individual components of distribution loss
You can now model 9 different individual components of Distribution Loss at a Supply Point. This is on a new, optional, separate tab:
Summary of minor changes
- Other minor bug fixes.
Community Plugin Changes
We have moved to .net 4.8.0 which requires Visual Studio 2019. We are planning on moving to .NET 6. The transition to .NET 6.0 won't be a quick process as some components we currently use will no longer be supported, however it does provide a potential pathway to running natively on Linux. Source can currently be run on Linux under Wine, but only natively on Windows.
Results and Configuration Changes
Some results have changed between Source 5.10 and Source 5.12. Changes include how marker constituent processing works in Weirs and how the confluences process unregulates sections of a network. Details are available here: /wiki/spaces/SC/pages/51643296
