Application of Probable Maximum Precipitation Estimates - United States East of the 105th Meridian

摘要

This study provides a stepwise approach to the temporal and spatial distribution of probable maximum precipitation (PMP) estimates derived from Hydrometeorological Report No. 51, 'Probable Maximum Precipitation Estimates - United States East of the 105th Meridian.' Included are discussions of the shape and orientation of isohyetal patterns for major rainfalls of record. An elliptical isohyetal pattern with a ratio of major to minor axes of 2.5 to 1 is recommended, and a procedure is outlined for obtaining appropriate isohyet values.
