This section lists all the Urban Developer node types, their characteristics and how their models operate.

See the node connection rules for a summary of how the node inputs and outputs are allowed to be connected.

Nodes represent a physical entity or process within the system that occurs on a relatively localised basis.

For example, a roof rainwater tank, mains supply point and/or waste water discharge point are all represented by nodes.

A water use node represents urban water demand and water consumption behaviour. The Urban Developer Plugin offers two methods for simulating water use behaviour:

The following table lists the node models currently available within the Urban Developer Plugin. Each node is represented by a specific icon. The table outlines the function of each node model; other sections of this User Guide contain a more comprehensive description of the each node model.

Wastewater Connection - A wastewater connection node is an optional end-point of the wastewater aspect of a modelled system.

RoofA roof node represents a physical roof catchment surface.

TankA tank is a type of storage used in domestic and industrial settings to store water from runoff, recycled water or a mains supply

and to release it in a controlled manner.

Other node types available in the Urban Developer Standalone Application, but not currently implemented in the Urban Developer Plugin include:

  • Alternative Supply - An alternative supply node represents any water supply stream in the model, such as bore water, snow melt, or others. An alternative supply node has no configurable parameters.
  • Impervious Area - An impervious area node is used to model catchment areas of zero infiltration, such as roads, driveways, parking lots, and other concreted or paved surfaces.
  • Junction - A junction is a point where outflows or runoff from two or more other nodes converge and are aggregated.
  • Pervious Area - A pervious area node models areas within the catchment that allow infiltration and seepage to groundwater.
  • Receiving Node - A receiving node is intended to be the most downstream node in a network, or part of a network, and is used for tracking purposes.
  • Subnetwork - A subnetwork is a characterisation of a group or cluster of dwellings, water uses or general water demands, as a discrete unit.
