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.
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.
Comparatively, by means of rain gauge hyetographs, the bias-corrected monthly TMPA-3B42R data were disaggregated to daily resolution.
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.
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).
Hyetographs (rainfall intensity as a function of time) for each runoff event are also shown in Figures 2 and 3.
