Abstract: This paper presents a simulation numerical model that can generate an oil‐risk map for a given area. The map shows monthly and yearly probabilities of oil‐slick presence for each grid area. The probability computation ...

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 ...

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, ...

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 ...

Abstract: Long waves coupled to and forced by groups of primary waves in water of uniform, but arbitrary depth are investigated. Stream function wave theory is used to represent the long waves, which are driven by a virtual pressure ...
