BURIAL AND SCOUR OF SHORT CYLINDERS AND TRUNCATED CONES DUE TO LONG-CRESTED AND SHORT-CRESTED NONLINEAR RANDOM WAVES PLUS CURRENTS

摘要

This paper provides a practical stochastic method by which the burial and scour depths of short cylinders and truncated cones exposed to long-crested (2D) and short-crested (3D) nonlinear random waves plus currents can be derived. The approach is based on assuming the waves to be a stationary narrow-band random process, adopting the Forristall wave crest height distribution representing both 2D and 3D nonlinear random waves. Moreover, the formulas for the burial and the scour depths for regular waves plus currents presented by Catano-Lopera and Garcia for short cylinders and Catano-Lopera et al.for truncated cones are used.
