Analysis of the spatial rainfall computed through spatial interpolation of point rainfall depicted a reduction of about 53-85 percent and 66-90 percent in volumes of rainwater during summer and winter seasons of the drought period, respectively.
Then, depending on the catchment size select an areal reduction factor to convert these point rainfall depths to catchment average rainfall depths.

Recent events (e.g., summer 1993 and July 1996) that produced significantly higher point rainfall totals in this region have created extreme social and economic impacts (Kunkel 1996; Changnon 1999; Changnon and Kunkel 1999).
where a and b are functions of frequency f and rain temperature t; the value of R is the value for an exceedance of 0.01% of the time for point rainfall rates with an integration time of one minute.
The storm testing is difficult, Morgenstern said, because it's hard to guess at what point rainfall has the "oomph" to push herbicides from the soil, or how quickly the chemicals reach the river.
Figure 3-8 provides adjustment factors for converting point rainfall over an area for storms of various durations.
Temporal patterns of storm rainfalls are derived by applying the commonly and easily used average variability method of Pilgrim and Cordery (1975) using point rainfall data.
