SEVERE RAINSTORMS IN THE VIDARBHA SUBDIVISION OF MAHARASHTRA STATE, INDIA

This paper discusses the results of Depth-Area-Duration (DAD) analysis of the 8 most severe rainstorms that affected the Vidarbha subdivisio n of Maharashtra State, India, during the 100 yr period from 1891 to 1 990. It was found from this analysis that rainstorms in June 1908, Jul y 1930 and August 1912 yielded greater raindepths for smaller areas, i .e. less than or equal to 1000 km(2) and less than or equal to 25 000 km(2), and that the August 1986 rainstorm yielded greater raindepths f or all the larger areas, for measurement periods of 1 to 3 days. The D AD raindepths of these severe rainstorms for different durations will be useful for the design storm estimates of different water resources projects in the Vidarbha region, as well as for checking the spillway capacity of existing dams.
