GENERALIZED PHYSICAL APPROACH OF ESTIMATING AREAL PROBABL MAXIMUM PRECIPITATION (PMP) FOR PLAIN REGION OF THE GODAVARI RIVER BASIN (INDIA)
Probable Maximum Precipitation (PMP) Depth-Area-Duration (DAD) analysis
2014/11/12
In this paper a generalized physical approach of estimating areal probable maximum
precipitation (PMP) for the non-orographic region of the Godavari river basin has been developed.
In this method,...
