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.

Node Models

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.

Node Types

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

IconNode NameDescription

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.

Average Water useA water use node represents representing average urban water demand and water consumption behaviour.

Behavioural Water useA water use node represents urban water demand and water consumption behaviour.

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