Abstract
Similar to the Stokes drift in periodic gravity waves, we introduce a second-order Stokes effect on the particle drift in isolated linear surface disturbances (pulses) in shallow water. For a linear disturbance with the shape and length scale of a KdV solitary wave, the model results agree surprisingly well with the observed drift in moderately steep solitary waves in the laboratory, as well as with more comprehensive theory for surface drift in solitary waves.
