demand area analysis,
00:32
calculates an unp profiled demand profile within a
00:35
demand management area and is typically domestic demand.
00:40
This profile represents the variation in demand for a single characterization of
00:44
demand and is stored as a demand pattern in a demand diagram.
00:48
The calculation of this profile is an essential part
00:51
of the calibration process which precedes a simulation.
00:55
A demand area within info
00:57
works. WS pro is defined by seed nodes and boundary conditions.
01:02
A seed node is picked at random either within a polygon or assigned area code
01:08
boundary conditions define objects at the extent
01:11
of the demand areas such as meters,
01:13
valves and pump stations.
01:16
A trace is carried out from the seed node to the bounding condition
01:20
and the resulting selection of nodes and links defines the demand area.

Recorded field data known as live data is needed to perform a demand area analysis.
02:03
The live flow data is utilized to perform a flow balance
02:06
on areas of the network to determine the unp profiled demand
02:10
inflow and outflow. Live data needs to be populated in the live data configuration
02:15
and the live data points must be linked to the relevant network objects.
02:20
Both the network and control object should be
02:23
open when defining the boundary conditions for demand areas
02:27
to allow the analysis of zone

Large metered consumers must be entered as direct demands
03:08
transfer nodes must not be used for this purpose.
03:12
A template demand diagram must be set up including demand
03:16
categories for all unp profiled demand and leakage demand.
03:19
To be calculated by the demand area analysis,
03:23
demand area nodes must be assigned to nodes or demand area polygons must be set up.

The demand area.
03:30
Grid view is used to generate demand areas and to view and edit data for each one
03:36
each time. A new demand area grid view is opened.
03:38
Seed nodes are randomly selected and the demand areas are retraced by tracing
03:43
through nodes with matching area codes or within the same polygon boundary.
03:48
Retracing of boundaries can also be requested by the user.
03:52
The results of demand area analysis can be copied to network objects to

Modeling the spatial and temporal characteristics of demand for water is one of the most important aspects of representing water supply systems.
A demand area is defined by seed nodes and boundary conditions. Demand Area Analysis is used to calculate essential information for each Demand Area.
IMPORTANT: Recorded field data, known as live data, is needed to perform a demand area analysis. The live flow data is utilized to perform a flow balance on areas of the network to determine the unprofiled demand. Inflow and outflow live data needs to be populated in the Live Data Configuration, and the live data points must be linked to the relevant network objects.
Other requirements for demand area analysis:
Before performing a demand area analysis in InfoWorks WS Pro, the following must be done:
The Demand Area Grid View is used to generate demand areas and to view and edit data for each one.
The results of demand area analysis can be copied to network objects to streamline mapping and provide users with more robust information on a model.
