The daily diurnal pattern contains regular (periodic) time series data and is used by the Average and Behavioural Water Use nodes to disaggregate daily demand into sub-daily values. The time series provided must be equi-spaced.
The Urban Developer Plugin uses a diurnal pattern based on Roberts et al. (2005) to vary the probability of water use events occurring throughout the day. The diurnal pattern is specified on an hourly basis according to the table below. The likelihoods are rescaled to 100%. Future versions of Urban Developer will enable users to input their own diurnal pattern.

| 2:00 am | 100 |
