Abstract

A generalised relationship between  maximum rain depth area and return period has been determined using Karoly and Alexander technique, For this purpose major rainstorms which affected Bihar region during the 65-year period from 1897 to 1961 were analysed and their depth-area-duration data utilized. The 3-day relationship has been found to be of the form d=-2. 76IogAlogT-4. 081og A+16. 03 logT+23.73. Based on this relationship a nomogram has been prepared with the help of which maximum 3-day rain depths can be obtained for different areas and return periods. Conversion factors have also been worked out for obtaining maximum ram depths for one and two-day durations for different areas end return periods.
