摘要：
L-moments method is briefly described and compared with classical methods of moments and maximal likelihood. Algorithms are given for calculating parameters of some distributions widely used in engineering hydrology, meteorology, etc. The advantages of L-moments method relative to alternative methods are analyzed for several examples.
