Abstract: The L-moment method was proposed by Hosking in 1990. It’s a new and good estimation method for flood frequency analysis, on which many studies have been performed abroad. The procedure of L-moment method for P-III distribution is first introduced for Chinese hydrologists, and a formula for L-moment method of P-III distribution with historical information is also proposed. A comparison with conventional estimation methods by Monte-Carlo method shows that L-moment method is of good statistical performance that the result from it is almost the same as PWM, and the new formula is effective.
