eWater is pleased to release Source 5.50, which captures improvements and enhancements from May 2024 to October 2024, key activities include:
Replicate Runner functionality
More Objective Function options
Farm Dams Node - Activation Date
Other enhancements and bug fixes
Replicate Runner:
Improvements to this functionality includes bug fixes as well as enhancements.
The way leap years are handled by the replicate runner has been defined:
If the model run date is a leap year and the replicate data is also a leap year, the original value on 29 February is assigned to 29 February for the model run
If the model run date is a leap year and the replicate data is not a leap year, the average of 28 February and 1 March is assigned to 29 February
If the model run date is not a leap year and the replicate data is a leap year, the original value in the replicate data on 29 February will be ignored in the model run
Replicate Runner results are now supported when calculating Annual Descriptive Statistics in Results Manager. Results can be summarised by scenario as well as by selected sub-runs within scenarios.
Objective Functions:
Four new objective functions been added to Source Calibration functionality and also to the statistics available in Source Results Manager. These include the Kling-Gupta Efficiency (KGE) statistic and three versions of a statistic proposed by Trotter et al (2023) which is an adaptation of the KGE to address the tendency of KGE (and NSE) to preference matching high flows:

Regression testing
There is no tolerance in our regression test suite to allow for earlier identification of results being different on different machines or versions of operating systems.
