Navigational channels are frequently maintained by the use of jetties. These stabilized channels often form long straight waterways which permit the passage of tidal flows and waves into harbours, lagoons, or rivers. This paper concerns the decay of the waves down the channel due to energy losses within jetties. The analysis involves the used of an impedance boundary conditions at the channel side walls to model the wave dissipation there. The wave motion is described by an eigenfunction expansion for the velocity potential within the channel, with and without tidal currents. For the case the water wave length is long with respect to the channel width and no currents are present, the wave height decay down the channel can be described by an exponential decay function.
