Wave induced forces around buried pipelines
TLDR
In this paper, the wave induced pressure on a pipeline buried in a sandy bed at different burial depth ratios is analyzed. But the results show that wave induced pressures are significantly controlled by the wave period analyzed in terms of the scattering parameter (ka).About:

Bedform evolution around a submarine pipeline and its effects on wave-induced forces under regular waves
TL;DR: In this article, an experimental investigation of seabed evolution behavior around a submarine pipeline and the hydrodynamic forces on the pipeline under regular waves was presented. And the influence of bedform evolution on wave forces was found to vary significantly in different regimes.

Scour protection of submarine pipelines using rubber plates underneath the pipes
TL;DR: In this article, the authors investigated the protection of scour around submarine pipelines under unidirectional flow using a rubber plate placed underneath the pipes and showed that there exists a critical pressure difference over which the movement of sediment and scour takes place.

Wave Induced Pressures in Permeable Seabeds
Hermann Moshagen,Alf Tørum +1 more
TL;DR: In this article, a theoretical investigation on the transmission of wave induced pressures into a permeable sea bottom has been performed, assuming that the soil water is compressible, while the grain skeleton is assumed rigid, the resulting theoretical model describes an effective mechanism by which the soil permeability affects the pressure transmission.
