Streamflow extreme indices were calculated using daily observed discharge data from 10 discharge stations (Mohggaon, Manot, Patan, Gadarwara, Sandia, Hoshangabad, Chhidgaon, Handia, Mandleshwar, Garudeswar) for the period of 37 years from 1979 to 2015 (Table 2). Rest stations at Narmada basin sites were discarded because of the unavailability of data for the concerned period. The discharge data have been obtained from Central Water Commission (India, WRIS). The daily rainfall data have been obtained from Indian Meteorological Department (IMD) at 0.25° resolution. The daily temperature dataset for the basin has been obtained from the Global Meteorological forcing dataset (GMFD) at 0.25° resolution.
