A tidal energy barrage has been proposed for the Severn Estuary, UK. In order to predict the effect such a structure may have on the tidal resonance in the channel, a simple two dimensional model has been developed for a series of simulated estuaries, ranging from a simple box channel with a uniform flat bed to a simple wedge shaped channel with a solid barrier across, to a simulation of the Severn Estuary with topographic and bathymetric values. These modelsshow amplitudes and phases of elevation and current flow for each model scenario. model outputs show that overall tidal resonance decreases with the construction of a barrier across a channel.
Numerical modelling of the response of tidal resonance to the presence of a barrage is located in United Kingdom.
