A sensitivity analysis of the influence of channel geometry over the impact of a tidal farm on water levels has been performed with idealised models of estuaries.
Blockage effects and sensitivity of the tidal response to friction have an important role.
In general, the effect of the tidal farm leads to an attenuation of the tidal range.
Loss of intertidal areas and positive effects on flood risk levels are potential environmental impacts derived from the tidal farm.
