Abstract:
A reliable and simple procedure has been developed for generating
short-time increment rainfall sequences in which a rainfall is defined as being
a continuous run of non-zero 10 minute yields. The procedure is a combination
of simple stochastic models designed to generate the duration of a rainfall, the
distribution of the 10 minute yields within a rainfall and the time intervals
between rainfalls. The model was fitted to the historical 10 minute rainfall records from
three climatically different regions of New Zealand. A comparison between the
same characteristics of the generated and historical data show that the overall
model to be a practical and yet a reliable method for generating short-time
increment rainfalls.
