The Urban Developer Plugin uses a default diurnal pattern based on Roberts et al. (2005) to vary the probability of water use events occurring throughout the day. This pattern is based on average total indoor water use volumes per household.
The daily diurnal pattern contains regular (periodic) time series data and is used in Urban Developer by the Average and Behavioural Water Use nodes to disaggregate daily demand into sub-daily values. The time series provided must be equi-spaced.
...
Currently, in the Urban Developer Plugin, the The diurnal pattern is not editable and is specified on an hourly basis according to the table , illustrated in Figure 1 below. The volume likelihoods are rescaled to 100% when the model is run.
...
The diurnal pattern is editable by the user and can be modified to reflect customised diurnal demands.

Restrictions
None
Dependencies
The diurnal pattern has no dependencies.
Outputs
The Average and Behavioural Water Use nodes use the diurnal pattern to disaggregate daily demand into sub-daily values.
