This section lists all the Urban Developer node types, their characteristics and how their models operate.
This section also describes the node connection rules, i.e. the inputs and outputs that are allowed to be connected.

| Icon | Node Name | Description |
|---|---|---|
| Roof | A roof node represents a physical roof catchment surface. |
| Tank | A tank is a type of storage used in domestic and industrial settings to store water from runoff or mains supply, and to release it in a controlled manner. |
| Average Water use | A water use node represents urban water demand and water consumption behaviour. |
| Behavioural Water use | A 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.

Node Connection Rules
The node connection rules are based on the link type allowed between each node output and input. When you draw links between outputs and inputs,
the UD plugin will prevent you from
configuring the links to join incompatible inputs and outputs together.
In
Node Model detailed descriptions, each node model input and output has a link type listed. The

The table below summarises these connection rules in one place.
To use this table, look up the originating node in the left-most column, then the output you want to connect (the destination node) in columns 2..29.
Example: from a roof node, you can connect the runoff output to a buffer, but not the runoff to tank output.
This table shows the allowed connections between a source node, and a destination node. The Destination node column specifies which output of the source node can connect to the nodes below it. If a node is not listed in the Destination Node column, the connection is not permitted. For example, the Impervious Area Roof node's Runoff to Tank output can connect to another Impervious Area a Tank node's Inflow input, or a Junction Rainwater / Stormwater Tank inflow, but not an Average Water Use node's Inflow inputRainwater / Stormwater inflow.If a node is not listed in the Destination
