Wavelet transforms are recent mathematical techniques, based on group theory and square
integrable representations, which allows one to unfold a signal, or a field, into both space …

This contribution provides a review of the most recent wavelet applications in the field of
earth sciences and is devoted to introducing and illustrating new wavelet analysis methods …

Context Numerous dams have been built in China to develop hydropower, a sustainable
and clean energy source. In recent years, the impact of dam construction on the regional …

A simple, nonrigorous, synthetic view of wavelet theory is presented for both review and
tutorial purposes. The discussion includes nonstationary signal analysis, scale versus …

The preface begins' Turbulence is a dangerous topic...'—with which any aircraft operator will
agree—but goes on'... which is often at the origin of serious fights in the scientific meetings …

Dam construction brings both benefits and harms to the ecological environment. This paper
focuses on the impact of the construction of mega-dams on regional climate. Based on the …

The wavelet decomposition is used to generalize the multifractal formalism to singular
signals. The singularity spectrum is directly determined from the scaling behavior of partition …

All objects considered previously have been identified by specifying that some measure
distributed on them is uniform: For example, the concentration on an isoconcentration …

Karstic watersheds appear as highly non-linear and non-stationary systems. The main focus
of this paper is a heuristic study of this non-stationarity using a time-scale localisation …

An assessment of local isotropy and universality in high-Reynolds-number turbulent flows is
presented. The emphasis is on the behaviour of passive scalar fields advected by …
