ASCE ( American Society of Civil Engineers )
Description: The American Society of Civil Engineers represents more than 150,000 members of the civil engineering profession in 177 countries. Founded in 1852, ASCE is the nation’s oldest engineering society. ASCE stands at the forefront of a profession that plans, designs, constructs, and operates society’s economic and social engine – the built environment – while protecting and restoring the natural environment.

Distributions of Wave Steepness and Surf Parameter
Publisher: American Society of Civil Engineers
Abstract: Predictions of wave action on slopes, and various wave- and depth-induced processes in the surf zone rely on two principal parameters: Wave steepness and surf parameter. For irregular waves, the theoretical distributions ...
Statistics of Wave Crests in Storms
Publisher: American Society of Civil Engineers
Abstract: The least-upper-bound (lub) theory recently proposed by Tayfun and Al-Humoud as a model for the statistical distribution of nonlinear wave crests is explored further. The theoretical distribution of the lub to the largest crest in
Least Upper Bound Distribution for Nonlinear Wave Crests
Publisher: American Society of Civil Engineers
Abstract: The exact form of the statistical distribution of nonlinear wave crests is not known. This study proposes and develops a theoretical least upper bound (
Distributions of Envelope and Phase in Weakly Nonlinear Random Waves
Publisher: American Society of Civil Engineers
Abstract: The representation of directional random waves in deep water under locally homogeneous conditions is examined in terms of the effect of second‐order nonlinearities on the wave envelope and phase. Theoretical expressions ...
Wave Envelope and Related Spectra
Publisher: American Society of Civil Engineers
Abstract: Theoretical forms of spectra associated with the odd and even powers of the wave envelope are examined. It is shown that spectral densities for the even powers of the envelope admit exact forms, whereas those for the odd ...
Envelope, Phase, and Narrow‐Band Models of Sea Waves
Publisher: American Society of Civil Engineers
Abstract: Two alternate sets of definitions for the wave envelope and phase which follow from the Rice‐Dugundji and Crandall‐Mark representation of random wave forms are compared. Theoretical constraints implied by these representations, ...
Nonlinear Effects on Wave Envelope and Phase
Publisher: American Society of Civil Engineers
Abstract: The effects of second‐order nonlinearities on the envelope and phase statistics of long‐crested sea waves are examined theoretically via the characteristic function expansion technique. Various cumulants typically required ...
High‐Wave‐Number/Frequency Attenuation of Wind‐Wave Spectra
Publisher: American Society of Civil Engineers
Abstract: Properties of surface‐elevation spectra representative of nonlinear deep‐water wind waves are examined theoretically. For a wave field characterized by second‐order nonlinearities, expressions describing the spatial ...
Distribution of Large Wave Heights
Publisher: American Society of Civil Engineers
Abstract: The statistical distribution of zero‐crossing wave heights is considered within the context of a previous theory proposed by the writer some years ago. The underlying model, definitions, and assumptions are reexamined ...
Joint Distribution of Large Wave Heights and Associated Periods
Publisher: American Society of Civil Engineers
Abstract: The joint probability density of zero upcrossing wave heights and periods is investigated over the range of large wave heights. The density of interest is expressed as the product of the marginal density of large wave ...
