Abstract

An approximate technique is presented for including the effect of turbulent bottom friction in the forced first-order wave equation governing long generalized coastal trapped waves. The resulting governing equations include both damping and a cross-shelf and vertical phase shift. A set of examples shows that damping of free waves decreases as the static stability increases, consistent with the inhibition of vertical motions by stratification.
