Abstract:

The most commonly used source of rainfall estimates is the U. S. Weather Bureau Technical Paper 40. A more detailed study of Pennsylvania storms was conducted in 1970 under the sponsorship of the Pennsylvania Department of Environmental Resources. The report resulting from this study shows some very pronounced areas of large and frequent rainfall amounts. In 1985, an agreement was reached with the Pennsylvania Department of Transportation to conduct an updated rainfall frequency study, using data up to 1983, and to present the results in the form of charts from which rainfall estimates could be read conveniently for durations between 5 minutes and 24 hours, and return periods between 1 and 100 years. The development of these charts is the main topic of this paper.
