Welcome to Source (public version). Just as with the full version, you can:

Context variables 

Context variables allow you to define a function using a parameter that returns different values based on the parameter's specific context. They can be used in rainfall-runoff models, nodes and links. Using context variables, you can define one function which will use different inputs depending on the context (ie. rainfall runoff model, node or link).

Off allocation node

The off-allocation flow sharing node is used to determine how much off-allocation flow is available in the river (at the node), as well as how to share this between the downstream water users that have licence shares. Off-allocation flows are those that are in excess of regulated requirements. They can be generated from unallocated tributary inflows downstream of storages, and from storage spills.

Ownership and the Transfer of Ownership node

Water ownership deals with the assignment and tracking of water as it is stored in, transits through, and exits river systems. This is an important aspect of water management, as it allows resource sharing amongst owners with the ability to determine how much water an owner has, and where it is located.

The transfer ownership node has two main functions in ownership systems:

Resource assessment

Many regulated river systems support several resource assessment schemes to share the available resource (water) among users. In Source, a resource assessment system:

There are three types of resource assessment supported in Source:

You can also configure the following attributes that make up the above three systems:

River Operations (limited functionality)

Operations forecasting allows you to create alternate forecasts for inflows, water demands, stream flow losses and gains (unaccounted differences) and constituents within a single overall project scenario. In other words, it forecasts the input data for a model. 

In Source (public version), operations cannot be enabled in a scenario. Consequently, a scenario cannot be run using the Run w/Warm Up analysis type.

Insight (limited functionality)

Insight is eWater’s multiple-objective optimisation decision support framework that allows for more efficient evaluation of planning options than the traditional manual trial and error approach that is often used. The main aim of Insight is to optimise decision rules for multiple objectives. The optimisation tool enables a more thorough examination of potential planning scenarios and the resulting trade-offs between desired outcomes.

Source (public version) allows you to undertake optimisation in a single scenario only. It does not allow you to load multiple files where you can carry out optimisation across multiple scenarios.
