The daily diurnal pattern contains regular (periodic) time series data and is used in Urban Developer to disaggregate daily demand into sub-daily values. The time series provided must be equi-spaced.
Currently, in the The Urban Developer Plugin , the 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 not editable and 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.
