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.
...
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:

Scenario Input Sets and the Export summary now include more information about Environmental Flow Actions. The path for the existing Scenario Inputs Sets will need to change from Rules → Actions. API details are in RM-16591. Terminology in the User Interface for one of the Initial Values at the start of run has been corrected during the process of developing the full API. Time since last successful season has been changed to Time since last successful spell in a successful season.
...
Confluences now also handle constraints for Unregulated sections of networks. For orders to be passed up to the splitter, constraints needed to be propagated down confluences. This improvement makes Confluences sum together the forecasts from each of its two branches when they are both unregulated.
River Operations Improvements
The Operations Tabular Editor has new options including Uncheck All for working with the active recorders:
From within View Overrides you can now Clear Historical Overrides:
Operations models now have a summary of Forecast models across the model
Hot start rainfall-runoff models
...
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
- Order Crawler now includes constraint factors. They are specified per owner, so when there are multiple owners in the system, we have included the average across owners. We also resolved a bug when there were multiple owners, the total wasn't always being shown and it was reporting the results for the first owner it found.
- Improvements to the Hydroclimate data transformation tool plugin (version 2.2), details and the new manual are available here: Hydroclimate Data Transformation Tool
- Scenario Input Sets now supports values that can go over one line. To use {MultiLineValue} include it after the = sign, and end it with {/MultiLineValue}. Example: MultiLineValue.txt
- Issues with date formats changing on different computers have been resolved by moving to exports based on yyyy-MM-dd HH:mm:ss. We will continue to import data from a variety of formats, however, tools such as Scenario Input Sets, and the Export Summary will now be using this format regardless of the user's local settings.
- An oversight in the algorithm to determine ownership at the splitter node has been resolved. Ownership at splitters could become negative in rare cases when sharing unallocated flows, it was previously assumed the allocated flow was always less than the actual flow.
- We no longer support node or link names with trailing white space. For example, nodes and links with names such as "Storage " won't be allowed to open in this version of Source. You will need to fix these names in a previous version of Source. These trailing white spaces were causing errors to occur in the results manager.
- Improvements to the Data Sources Overview
- Auto export results now use the dimension Display Units
- The Simulation log file has more content for Data Sources
- New Scenario creator Single Catchment Scenario Builder
- Other minor bug fixes.

Some results have changed between Source 5.0 4 and Source 5.410. Changes include how marker constituent processing works in Weirs and how the confluences process unregulates sections of a network. Details are available here: 5.10 Results and Configuration Changes from 5.4
