What is Probable maximum precipitation (PMP)?

Probable maximum precipitation is defined as the estimate of the extreme maximum rainfall of a given duration that is physically possible over a basin under critical hydrological and meteorological conditions. This is used to compute flood by using suitable rainfall runoff model. Two methods of PMP estimation are: 1. Statistical procedure 2. Meteorological approach
