Abstract

Highlights: A simple analytical method to predict the wave-induced current on mild slopes. The surface Stokes drift and volume Stokes transport are obtained for random waves. An example using data typical for field conditions is provided. Assessment of random wave-induced current is based on available wave statistics. Abstract: This paper provides a simple analytical method for calculating the wave-induced current due to long-crested random waves on mild slopes. The approach is based on assuming the waves to be a stationary random process, adopting the Battjes and Groenendijk (2000) wave height distribution for mild slopes. An example is included to demonstrate the application of the analytical method for practical purposes using data typical for field conditions; the significant values of the surface Stokes drift and the volume Stokes transport are calculated. The present results can be used to make assessment of the random wave-induced current based on available wave statistics.
