Rainfall Analysis is pre-requisite for designing efficient storm water management system. This paperincludes the most accurate methodology for developing Rainfall Intensities-Duration-Frequancies (IDF) relationships.Vadodara city is taken as study area to design efficient River-lake interlinking system. For this, first necessary step isproper understanding of rainfall pattern and development of IDF curves. Daily Rainfall data (1970-2015) from gaugestation in Vadodara city was analysed by Flood Frequency analysis by Gumbel’s extreme value distribution to deriveprobabilities of daily maximum rainfall events using spread sheet., Rainfall intensities were derived for 60, 90, 120, 180,240, 360, 480, 720, 1440 min of duration, this intensity duration relationship were plotted with log-log plot for 1 & 2year return period. This particular return period was adopted for storm water management. Relationship of rainfallintensity with concentration time for a given frequency of occurrence for 10 min & 30 min intervals were plotted togenerate IDF curves which will be considered as one of the important input parameter to design River-lake interlinkingsystem.
