The Akaike information criterion (AIC) is a useful tool for choosing the best flood frequency distribution. It balances how well the distribution fits the data with the uncertainty from extra parameters. A study tested the AIC on 42 Canadian hydrometric stations and found it helpful in selecting the right distribution. This method can improve flood analysis by considering both goodness of fit and parameter uncertainty.
