Most of the hydrological and hydraulic studies refer to the notion of a return period to
quantify design variables. When dealing with multiple design variables, the well-known …

Estimates of flood event magnitudes with a certain return period are required for the design
of hydraulic structures. While the return period is clearly defined in a univariate context, its …

Compound climate extremes are receiving increasing attention because of their
disproportionate impacts on humans and ecosystems. However, risks assessments …

The most powerful earthquake in 40 years occurred on 26th December 2004 off the west
coast of Sumatra, Indonesia. The tsunami it generated turned into one of the worst known …

In this paper we provide a general theoretical framework exploiting copulas for studying the
return periods of hydrological events; in particular, we consider events depending upon the …

The concept of return period in stationary univariate frequency analysis is prone to
misconceptions and misuses that are well known but still widespread. In this study we …

Calculating return periods and design quantiles in a multivariate environment is a difficult
problem: this paper tries to make the issue clear. First, we outline a possible way to …

This paper is of methodological nature, and deals with the foundations of Risk Assessment.
Several international guidelines have recently recommended to select appropriate/relevant …

The use of copulas in hydrology is quite recent, and many important results still are to be
discovered and/or derived. In this work we present some recent advances in hydrological …

Multivariate extreme value models are a fundamental tool in order to assess potentially
dangerous events. The target of this paper is two‐fold. On the one hand we outline how …
