Abstract Due to climate change, variable rainfall pattern and rapid urbanization during last two decades, Vadodara district is frequently facing problems related to flooding. In present research paper frequency Analysis is carried from the available hydrometeorologicalhistorical rainfall data series of past four decades for Vadodara District, Gujarat. Rainbow software is used to carry out the analysis. Homogeneity of data is checked and Goodness-of-fit is tested. A logarithm transformation is selected to plot magnitude of event and corresponding probabilities of exceedance. The mixed Global probability distribution is used to explore the re-occurrence of rainfall events with certain return period.
