Abstract
Depending on the type, scope and location of the project, availability of data, stage of the study and other considerations, the probable maximum precipitation (PMP) used in the probable maximum flood (PMF) analysis may be a generalized estimate taken from publications such as: Hydrometeorological Reports 49 (9) and 51 (10) published by the U.S. National Weather Service. It also may be estimated based on a site specific study by a hydrometeorological analysis, application of hurricane model or a statistical method. A number of case studies, each for a project of different nature and scope located in an area of different physiographic and climatic conditions, is presented. The amount and quality of data available for each project are also different. By presenting these case studies, the writer wishes to share his experience on application of available techniques for the estimates of PMP which is often required in the selection of design flood for major dams and spillways.
