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.
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 diurnal pattern is specified on an hourly basis according to the table below. The likelihoods are rescaled to 100%. The diurnal pattern is editable by the user.
| Hour | Likelihood |

| 1:00 am | 200 |
| 2:00 am | 100 |
| 3:00 am | 50 |
