What is Source?

Welcome to Source - an application that can be used for both catchment and river modelling. Source provides a flexible structure that allows you to select a level of model complexity appropriate to the problem at hand and within any constraints imposed by your available data and knowledge. You can construct models by selecting and linking component models from a range of available options.

Source is designed to:

  • Support the construction and operation of river models that mimic river behaviour. Water resource systems can be analysed for periods that range from days to many years; and
  • Allow you to construct and interrogate water and contaminant transport models to assess the impact of future change, on parameters of interest.

You can build various kinds of scenarios, including:

  • Basin planning scenarios,
  • River Operator scenarios, which are intended to support day-to-day operations; and
  • Catchment scenarios, which are intended to model water quality constituents (eg. salinity).


Note: There are two versions of Source versions available - a version that allows unrestricted access to all parts of Source, and Source (public version), that provides limited access. Refer to Source versions for more information on what is available in both.

Source Training Courses

We deliver Source training packages to provide a structured pathway to proficiency certification in Source Modelling for Industry, Governments and Development Partners.  We offers following five tiers of training which will lead towards proficiency certification in the use and customisation of Source:

  1. Fundamentals in Source Hydrological Modelling
  2. Advanced Topics in Source Hydrological Modelling
  3. Source Catchment and Water Quality Modelling Specialist
  4. Source Water Resources Assessments and Water Sharing Modelling Specialist
  5. Source Customisation Specialist (for ICT Professionals)

Training can be delivered in a range of formats to suit you, including face to face workshops, online training modules and live webinars. View our course calendar for upcoming dates,


Using the Source User Guide 

The Source User Guide provides:

  • information on operating Source, including specifying catchment geometry, selecting component models, generating river models, running a project and viewing results;
  • an overview of the broad concepts underlying Source;
  • information on data formats compatible with Source; and
  • The Scientific Reference Guide, which provides the scientific background of each component used in Source.

To get started you can choose a topic of interest from the navigation panel on the left, or from the topic links below.


Scientific and Technical Reference

The Source Scientific Reference Guide details the theory behind the software, including scientific provenance, parameters defaults and recommended ranges, relevant algorithms and references.



Note: To access some sections of the user guide, including some sections Scientific and Technical Reference section you will need an eWater account ID, which can be created for free on the Toolkit website. Use your eWater account ID and password to login to Confluence, Toolkit and Source. If you have trouble logging into Confluence please contact us.

We welcome comments on how the quality and effectiveness of the User Guide can be improved. To add comments you will need to be logged into Confluence, and a comments field will appear at the bottom of each page. All comments will be viewed by the Documentation Team.

Accessing the online documents

You can access the Source User Guide online in one of two ways:

  • By following the links within the Source software. The Help menu or the feature editors (nodes or links) contain links to the user guide and scientific reference guide; or
  • By navigating to wiki.ewater.org.au, and select Source User Guide 4.9 from the menu on the left.

Refer to Source revision history for the release notes.

Guidelines for water management modelling

As a major provider of modelling products, eWater is responsible for ensuring they are well used. To this end, a set of generic guidelines have been published to promote a best practice, quality assured approach for:

  • The application of modelling tools, primarily to address water management problems; and
  • The provision of decision support to end-users of model results.

These guidelines cover risk assessment, decision support, and communication and interaction between you and end-users of model results, as well as technical aspects of modelling. They also provide a framework for a series of guidelines relevant to the application of certain functionality in Source, such as modelling storages and wetlands, modelling water sharing rules and uncertainty analysis.

This "key" symbol is associated with recommendations and guidelines for best practice modelling provided by a panel of experienced Source users. However, they are not necessarily appropriate in every situation. You should always rely on your own judgement and experience to decide whether to incorporate a particular recommendation or guideline into your model.


It is highly recommend that you read “Guidelines for water management modelling” before selecting a modelling platform for your application. Following these guidelines is a critical aspect of developing robust, reliable and defendable models. They can be accessed from eWater's Toolkit.
