This study was designed to find the best-fit probability distribution of annual maximum
rainfall based on a twenty-four-hour sample in the northern regions of Pakistan using four
probability distributions: normal, log-normal, log-Pearson type-III and Gumbel max. Based
on the scores of goodness of fit tests, the normal distribution was found to be the best-fit
probability distribution at the Mardan rainfall gauging station. The log-Pearson type-III
distribution was found to be the best-fit probability distribution at the rest of the rainfall …
