Temporal Distribution of Rainfall in Virginia: Final Report

Report No: 85-R29

Published in 1984

About the report:

The temporal distribution of Virginia rainstorms was examined by statistically analyzing approximately 1,400 storm events recorded throughout the state. Rainfall time distribution curves were constructed and were compared with several nationally recognized curves such as the Huff quartile curves and the Soil Conservation Service Type II curves. Significant differences were found between the Virginia distribution and the national curves. No regional variation was observed in rainfall distribution for storms of six hours or longer duration, However, regional variation was appreciable for short duration storms. Design rainfall distribution curves, as well as equations describing the curves, are presented in this report.
