โœฆ Synopsis

Near-resonant free-surface flows over a wavy bed of either finite or semi-infinite extent are considered. For a bed of finiteextent wavy profile of a small amplitude, it is shown that the linear model is valid and a steady state exists even within the resonant regime, with an "upstream influence". If the bed extends semi-infinitely to far downstream, the linear model breaks down in the near field, where the motion is governed by a series of forced KdV equations, which are matched to the far-field linear solutions.

adopts a gradient-diffusion form for Z, whilst Bradshaw et al. (1967) argue against such a form; however, the modifications of the present (Z = 0) results implied by either Townsend's Z or that of Bradshaw et al. are relatively small.
