HMR52, Probable Maximum Storm (Eastern United States). Users Manual
Abstract
Computer program HMR52 computes basin-average precipitation for Probable Maximum Storms (PMS) in accordance with the criteria specified in Hydrometeorological Report (HMR) No. 52 (National Weather Service, 1982). That HMR describes a procedure for developing a temporal and spatial storm pattern to be associated with the Probable Maximum Precipitation (PMP) estimates provided in HMR No. 51, Probable Maximum Precipitation Estimates - Unites States East of the 105th Meridian. Data required for application of the HMR52 program are: (1) X, Y coordinates describing the river basin and subbasin watershed boundaries; (2) PMP from HMR No. 51 (NWS, 1978); and (3) storm orientation, size, centering and timing. The program computes the spatially average PMP for any of the subbasins or combinations thereof. The HMR52 computer program will optimize the storm area size and orientation in order to produce the maximum basin-average precipitation. The user must provide the desired centering and time distribution for the storm. The HMR52 program will produce a precipitation data file which can subsequently be input to a rainfall-runoff model, such as HEC1. Keywords: Computer program documentation.
