Abstract

Mean monthly and annual rainfall for the Godavari basin up to Paithan dam site have been worked out by the isohyetal method, Mean annual rainfall has been found to be of the order of 29 Inches.

 

The study has revealed that in the central parts of the catchment coefficient of variability is the highest and is of the order of 40 to 44 per cent for monsoon (June to October) rainfall.

 

Seventy-three heaviest rain spells, one for each, year of the 73-year period (1891.to 1963), have been studied by depth-duration method as well as by the Gumbel s statistical method and the design storm rainfall depths have been worked out for the return periods of 100, 200, 500 and 1000 years.
