Gupta and Waymire (1990) studied the concepts of simple and multiple scaling to characterize the probabilistic structure of the precipitation process, Koutsoyiannis and Foulfoula-Georgiu (1993) used a scaling model to predict storm hyetographs. Menabde et al.
(3) Generate the rainfall excess hyetographs for a given rainfall depth, temporal pattern and a range of durations using a conceptual loss model.
The first involves generating a complete hydrograph from the rainfall hyetograph; the second is based on a dimensional argument, relating the effective runoff rate to peak rainfall intensity and gross runoff coefficient.
The variation of rainfall with time or hyetograph is characterised by a maximum rainfall depth and a temporal pattern or shape.
By concentrating on the most important aspect of a storm hyetograph rather than the temporal variation of rainfall intensity within each storm event, application of physically based soil erosion models could be made easier because the number of model parameters required to drive the weather generators can be reduced considerably.
Finally, the paper by Singh, Griffiths, and McKerchar (2018) provides 'Temporal patterns for design hyetographs in New Zealand'.
Data sets recorded by each station were precipitation to produce rainfall hyetographs and water depth which were converted to flow rate to produce runoff hydrographs at the inlet and outlet of the monitoring constructed wetland for the storm events investigated.
One of the most widely used design hyetographs is the Soil Conservation Services (SCS) hypothetical storms profiles (see Figure 1).
Comparatively, by means of rain gauge hyetographs, the bias-corrected monthly TMPA-3B42R data were disaggregated to daily resolution.
A storm selection criterion was established, 104 rainfall events occurring between May 2002 and December 2004 were selected and hydrographs and hyetographs were plotted for each storm.
Monthly hyetographs observed at the site weather stations showed that rainfall events occurred between July and October (winter) with little rainfall between November and March (summer).
