eWater is pleased to announce the latest Production Release of Source version 4.11. Highlights of Source Version 4.11 include:

The biggest feature in this release is Combine catchments and changes to the Calibration tool. It also includes:
- Climate Data import tool improvements, including the ability to extend the duration of data
- Zoom all the time with the scroll wheel for Catchment Scenarios
- A fix for projects being corrupted by windows that affected a small number of users
- Modelled variables being more stable when moving links.
The significant change for this release is the ability to Version 4.11 includes three significant features:
- You can now combine sub-catchments in a geographic scenario.
- The Calibration tool has been changed from a flow calibration tool to a generic calibration tool.
- You can use the new Environmental flows work with NetLP
...
- .
Combine Subcatchments
You can now combine sub-catchments in a geographic scenario:
...
At the moment you need to have a single outlet for all of the sub-catchments you are combining. We will relax this restriction This restriction will be relaxed in future versions.
At Selected Node Boundaries:
...
You can select a single node and combine all of the catchments upstream of it.
Calibration tool enhancements
The calibration tool has undergone significant enhancements. It has been changed from a flow calibration tool to a generic calibration tool. You can now specify any recordable output (including functions) to be used as part of the objective function in the calibration wizard. The independent variable can now be a Data Source, rather than a separately loaded text file.

The new Environmental Flow node and Environmental Flow Manager now work with NetLP ordering. To determine the "marginal" difference in orders that are required by the Environmental Flow Node, NetLP determines probable flows throughout the system prior to determining environmental flow orders. The model does the order phase twice - firstly Expected Flows without initiating new Environmental Flow orders are determined. These flows are then provided to the environmental Flow Nodes to perform their ordering calculations. NetLP is then given the environmental flow demands as well as all of the other demands . The system then resolves.
...
and works out the most efficient way to deliver the orders.
Minor changes
- Improved generation of orders at Storages and Weirs. Source now allows the user to specify a factor to smooth the rate at which downstream storages orders water from upstream.
- Off allocation had an option called "Equalise Shares", which wasn't used by any of the jurisdictions, and has now been removed.
- climate Data import tool improvements, including the ability to extend the duration of data
- zoom all the time with the scroll wheel for Catchment Scenarios
- a fix for projects being corrupted by windows (affected a small number of users)
- modelled variables are now more stable when moving links
- optional improvement of ordering using Operating Targets with Rules-based orders at storages
- resolution of infinite loops
- Insight now produces a cache of model run results
- addressed some charting issues.
Infinite loops removed from Off Allocation and the Environmental Flow Manager
We have modified Off Allocation and Environmental Flow Manager distribution logic to remove the infinite loops which that could occur in some models.
The changes in this beta will be available in the 4.11 production release, due at the end of December 2019.
Chart changes
We have resolved a number of issues identified with charts and the mass balance tool since their redevelopment.
Chart aggregation can now ignore null values. This allows for the aggregation of seasonal data to an annual time series. e.g. you can now generate a series of the total summer inflows each year.
Insight changes
Insight now produces a file which is a cache of model run results. This means that when you run an insight optimisation and then decide to increase the number of generations of the optimisation, you can continue the extended optimisation from the end of the previous optimisation. This This also means you can stop an insight run and restart it without wasting a large amount of time.
