Changes in the hydrologic cycle due to increase in greenhouse gases cause variations in intensity, duration, and frequency of precipitation events. Quantifying the potential effects of climate change and adapting to them is one way to reduce urban vulnerability. Since rainfall characteristics are often used to design water structures, reviewing and updating rainfall characteristics (i.e., Intensity–Duration–Frequency (IDF) curves) for future climate scenarios is necessary. The present study regards the evaluation of the IDF curves for Four raingauge stations of Bangalore rural : Anugondanahalli, Devanahally, Doddabalapura and Hoskote. Starting from daily rainfall observed data, to define the IDF curves and the extreme values in a smaller time window (2, 5, 10, 15, 30, 60, 120, 720, 1440 minutes), disaggregation techniques of the collected data have been used, in order to generate a synthetic sequence of rainfall, with statistical properties similar to the recorded data. Then, the rainfall pattern of the Four raingauge stations was analyzed and IDF curves were evaluated
