Abstract: The mean current velocity profile in the combined wave‐current motion is calculated by use of the depth‐integrated momentum equation. The velocity distribution is assumed to be logarithmic inside as well as outside the ...

Abstract: A review of the existing research on the interaction between a pipeline and an erodible bed exposed to waves and/or currents is presented. The review covers three topics: scour, liquefaction, and lateral stability of ...

Abstract: The development of the turbulent boundary layer around a circular cylinder in oscillatory flow is investigated by the depth integrated equation of momentum. The shape of the velocity profile is assumed to be log‐linear. ...

Abstract: By means of detailed mathematical modeling the processes responsible for the morphological evolution of small-scale excavations exposed to wave-induced flow are investigated. The problem is relevant when assessing rates ...

Abstract: An empirical relation for the bed concentration of suspended sediment

Abstract: This paper presents the results of an experimental study on scour around a pile subject to combined waves and current. Irregular waves were used in the experiments, which were carried out both for codirectional waves and ...

Abstract: This paper considers the lift forces acting on a pipe with or without a small gap between the pipe and the seabed. From simple physical considerations, it is explained why the potential theory that predicts a downward lift ...

Abstract: This paper presents the results of an experimental investigation on scour below pipelines exposed to waves. The effect of lee‐wake of the pipe is the key element in the scour process, and it is demonstrated that the ...
