Floods cause environmental hazards and influence on socio-economic activities. In this study, we evaluated the historic flood frequency at a confluence in the middle Yellow River, China. A non-parametric, multivariate, empirical, orthogonal function matrix model, which consists of time correlation coefficients of flood discharge at different gauge stations and flood events was used for the anal...

River flow extremes constitute a complex random process in both space and time. In this paper, some basic characteristics of flood flows considered as a spatial process are reviewed and discussed. Of particular interest are both marginal and joint distributional properties of annual peak flows at a collection of points in some large region. Two widely used regionalization methods for modeling t...

Recent evidences of the impact of persistent modes of regional climate variability, coupled with the intensification of human activities, have led hydrologists to study flood regime without applying the hypothesis of stationarity. In this study, a framework for flood frequency analysis is developed on the basis of a tool that enables us to address the modelling of non-stationary time series, na...
