eWater is pleased to announce the latest Production Release of Source version 5.10.
...
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
...
The user interface has been consolidated to a single tab, and it's been made clear that it has currently only been implemented for GR4J and Sacramento.
Calibration Improvements
...
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:
Environmental Flow Node and Environmental Flow Manager
...
When working with large models with significant scenario modelling with Scenario Input Sets, it can be hard to recognise that Input Sets may change the run-time configuration. We have included Scenario Input Sets in each feature editor to show the number of changes to the current node/link across the Scenario Input Sets:
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:

- 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 export 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 computer 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.
- Confluences now handle constraints for Unregulated sections of networks. We introduced changes to allow splitters to be considered regulated in 5.6 - Beta Release (February 2021). 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.
- When using the Shuffled Complex Evolution optimisation function, you can now run multiple instances of Source to improve the speed of the calibration: This can be run through the User interface or through the commandline.
- 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.
- Other minor bug fixes.

- Improvements
...
- Calibration using Parallel runs within Source,
- Hot Start Rainfall Runoff Models,
- Improvements to the Data Sources Overview,
- Ability to model individual components of distribution loss and
- a number of minor improvements.
Calibration using Parallel runs within Source
...
This can be run through the User interface or through the commandline.
Hot Start Rainfall Runoff Models
When running Rainfall-runoff models GR4J or Sacramento, you can now take a Snapshot of their internal state variables:
This can then be saved to a file and applied at the start of a model run:
This removes the need to do a warmup period for running rainfall-runoff models.
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:
Data Sources Overview Improvements
...
- the
...
- Data Sources Overview
...
- Export to csv,
- Number of usages,
- Column filtering and sorting, and
- a new Usages view of where the Data Sources are used in the model.
You can also Group By columns. e.g. This is grouped by the Water Feature Type:
Minor changes
- Auto export results now use the dimension Display Units,
- The Simulation log file has more content for Data Sources,
- New recorder on confluences: Constrained Historical Order For Long Branch
- New Scenario creator Single Catchment Scenario Builder:
- 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 5. The transition to .NET 5.0 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.
