In this study, the monthly streamflow data for the period 1972-2007 and the daily rainfall data for the period 1972-2005 have been analyzed using the Mann-Kendall nonparametric test after removing serial correlation. The results reveal a substantial spatial and subseasonal difference in the monsoon season streamflow and rainfall patterns, with a predominance of the increasing

The correlation coefficients show a direct correspondence of the rainfall and streamflow series with the El Niño-Southern Oscillation (ENSO), which is contrary to the established inverse relationship over India. The noteworthy feature of this study is the observed

Strong evidences have emerged regarding the basin-wide increases in extreme rainfall indices. In particular, the coastal sector of the basin is more vulnerable to the heavy rainfall, whereas the southern Eastern Ghats region is susceptible to the
