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.
Node Types
Roof| Node Icon | Node Name | Purpose |
|---|---|---|
| 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. |
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, Urban Developer prevents you from connecting incompatible inputs and outputs together.
In the node model section (page 91), each node model input and output has a link type listed. The rule is: you can only connect inputs and outputs of the same link type: demand to demand, stormwater to stormwater, etc.
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. For example, the Impervious Area node's Runoff output can connect to another Impervious Area node's Inflow input, or a Junction node's Inflow input.
If a node is not listed in the Destination Node column, the connection is not permitted.
| Node Icon | Node Name | Node Output Destination node - destination input type |
|---|---|---|
| Roof | Runoff to tank Junction - Inflow Receiving Node - Inflow Subnetwork - Piped inflow Tank - Inflow Runoff Impervious Area - Inflow Junction - Inflow Pervious Area - Inflow Receiving Node - Inflow Subnetwork - Surface inflow, Piped inflow Tank - Inflow |
| Tank | Spill Impervious Area - Inflow Junction - Inflow Pervious Area - Inflow Receiving Node - Inflow Subnetwork - Surface inflow Detention Outflow Impervious Area - Inflow Junction - Surface inflow, piped inflow Pervious Area - Inflow Receiving Node - Surface inflow, piped inflow Subnetwork - Surface inflow, piped inflow Tank - Piped inflow Supply Out Alternative Supply - Inflow Mains Water Supply - Inflow Subnetwork - Mains supply, Tank supply, Alternative supply 1 & 2 Tank - Inflow Wastewater Connection - Inflow Water Use - Mains supply, Tank supply, Alternative supply 1 & 2 |
| Average Water use | Greywater Subnetwork - Piped inflow Tank - Inflow Wastewater Connection - Inflow Blackwater Subnetwork - Piped inflow Tank - Inflow Wastewater Connection - Inflow Irrigation/Other Pervious Area - Inflow Subnetwork - Surface inflow, piped inflow Tank - Inflow Wastewater Connection - Inflow |
