Operating Guidance 8-12: Joint Probability - Optimal Sampling Method for Tropical Storm Surge Frequency Analysis
The purpose of this guidance document is to simplify the application of, and ensure correct implementation of, the Joint Probability Method (JPM) approach. The procedures outlined in this guidance were developed during the intensive efforts by FEMA and the USACE to reevaluate coastal hazards in the Northern Gulf following Hurricanes Katrina and Rita of 2005. In order to simplify their application and to ensure a correct implementation of some of the methods not commonly encountered in past FEMA studies, two utility programs have been written. One is a console program, SURGE_STAT, to compute the surge statistics at the target sites, including the effects of secondary parameters. The other is an Excel spreadsheet, JPM-OSQ.XLS, to select the parameters of the OS storms, according to the quadrature methods. The programs and User’s Manuals are available to Mapping Partners upon request to the FEMA Project Officer.
