Daily rainfall data obtained from the rain,gauge station, Sulur (11 degrees N and 77 degrees E) were analyzed for fitting one day maximum rainfall, average weekly, monthly and seasonal rainfall data, using different distributions like Normal, Log-normal, Gumbel and Log-Pearson III to determine the best fit distribution. Over the study area: the Gumbel and Normal distribution distributions are identified for the estimation of one day maximum rainfall, the average weekly and monthly rainfall with minimum D-index. However for seasonal rainfall, all four distribution viz. Gumbel, Log-normal, Log-Pearson III and Normal distributions gave relatively low D-index values with minimum in Gumbel distribution.
