Source versions

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

• Build and run a catchments scenario;
• Develop river operator scenarios to support day-to-day operations;
• Input data in several ways, including with the Function manager or the Climate data Import tool;
• Use additional analysis tools and plugins; and

• Run and analyse the results using the user interface only now.
  
  

Restrictions on functionality are detailed below:

• Limited Node palette (i.e. not all nodes are available)
• Limited to 20 Nodes & Catchments in total (excluding confluence nodes)
• Simple Function editor
• Simple Calibration tool (limited to 1 objective function and 1 calibration engine)
• Plug-in capabilities but specific Plugins will be available separately via the Plugin Store
• Basic IT/Installation support included
• Some scenario management tools are not available (such as Import/Copy Scenario Functionality, Scenario Diff tool and Scenario Input Sets)
• Some edit tools such as Feature Table and Tabular Editor
• User Logs (Note: it is not Log Reporter) are no available
• NetLP optimisation is not available
• GN1D groundwater flux model are not available
• Constituents and Water Quality models (i.e., Constituents generation, Constituents filters, Routing and Storages) are not available

Details of what Source Modules are available here: https://ewater.org.au/products/ewater-source/ewater-source-access-and-pricing-policy/

These components of Source are not available in Source (public version). 

Full Function Editor (limited functionality)

Only Modelled variable  is available in Source (public version). Most types of variables including Pattern variable, Time series variable, Piecewise linear variable , Bilinear variable and Context variable are not available in Source (public version). 

• Pattern variable - creates a dataset of repeating time-dependent values (eg. daily or monthly pattern). Value used is based on the current simulation date and time;
• Time series variable - uses a time series data source as input. Value used is based on the current simulation date and time;
• Piecewise linear variable - creates a lookup table that interpolates a Y value based on an X value. 
• Bilinear variable - similar to a piecewise linear variable, but allows you to look up and interpolate between values in two dimensions;
• Context variable - for applying the same function in a number of locations that use modelled variables.

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.

Bulk Licensing node

The Bulk Licensing Node is used to represent an administrative arrangement where a group of water users share a common portfolio of accounts.

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:

• To manage the transfer of flow between owners at a given point in an ownership system; or

• To act as a boundary between adjacent ownership systems by managing the transfer of orders and flow at the boundary.

Scenario Transfer node

The Scenario transfer node (STN) handles the joining of two scenarios and conceptually comprises of two components, the Upstream STN and Downstream STN (as shown in Figure 1). The node links two scenarios and runs them together. Constituents, orders and ownership are passed between the two scenarios. However, off allocation does not operate over scenarios, instead, the STN operates like an off allocation boundary - similar to the Transfer Ownership node.

NetLP Parallel Arcs node

The NetLP Parallel Arcs node allows you to define multiple parallel arcs with different capacities and costs at a particular location, to influence the flow in a network. Each arc can be used to represent different flow requirements at a location, such as an environmental or hydrological demand, or flood flow. Note: This node can only be used in NetLP-based ordering.

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:

• is associated with only one scenario in a project, whereas a scenario may be associated with one or more resource assessment systems;
• can only have one owner, but any given owner or water user may be affected by more than one system; and
• supports multiple account types.

There are three types of resource assessment supported in Source:

• Annual accounting - This is a custom assessment method for regulated water;
• Continuous accounting - This replicates the resource assessment system used in the Gwydir and Namoi in NSW; and
• Continuous sharing - In this system, the behaviour of a water user has as little effect as possible on other water users within that system. 

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

• Accounts - Water users within a model are linked to accounts, that allow them to request resources;
• Usage limits - Limits the amount of resource that can be delivered to water users;
• Account type triggers - A trigger initiates or cancels certain actions for an account type; examples include dates and water levels; and
• Off allocation 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.
