This book is the first complete account of the L-moment approach to regional frequency analysis of environmental extremes.Extreme environmental events, such as floods, and high winds, have severe consequences for human society. Estimation of these frequencies is difficult as extreme events are by definition rare and the data record is often short. Regional frequency analysis resolves this problem by combining data from several sites to estimate event frequencies at any one site. This book is the first complete account of the L-moment approach to regional frequency analysis. It describes the theoretical background to the subject, is rich in practical advice for users, and contains detailed examples that illustrate the approach.Extreme environmental events, such as floods, and high winds, have severe consequences for human society.

Regional frequency analysis helps to solve the problem of estimating the frequency of these rare events at one site by using data from several sites. This book is the first complete account of the L-moment approach to regional frequency analysis. Regional Frequency Analysis comprehensively describes the theoretical background to the subject, is rich in practical advice for users, and contains detailed examples that illustrate the approach. This book will be of great value to hydrologists, atmospheric scientists anlS&
