Long- and short-crested random wave-induced scour below pipelines Available to Purchase

This paper provides a stochastic method by which the maximum scour depth and the maximum scour width below pipelines exposed to long-crested (2-D) and short-crested (3-D) non-linear random waves can be derived. The approach is based on assuming the waves to be a stationary narrow-band random process and adopting the Forristall wave crest height distribution representing both 2-D and 3-D non-linear random waves, and by using the regular wave formulae for scour depth and scour width derived in earlier research studies. An example calculation is provided. Tentative approaches to related random wave-induced scour cases are also suggested.
