HMR52 Overview

BOSS HMR52, based on HEC's HMR52 program, helps engineers compute basin-averaged precipitation for Probable Maximum Storms (PMS), and corresponding spatially-averaged Probable Maximum Precipitation (PMP) for a basin or combination of watershed sub-basins. The HMR52 Modeling program employs the procedures specified in the NWS's Hydro-meteorological Report No. 52, which pertains to the Central and Eastern United States. Click for details
