We would like to thank Prof. Behzad Ataie‐Ashtiani for his explanatory comment on our paper [Ataie‐Ashtiani, 2015]. He notes that in confined aquifers with a vertical seaside boundary, a tidal overheight does not develop. This is in contrast to an unconfined aquifer for which a tidal overheight may develop when the tidal amplitude is significant relative to the saturated thickness, in particular in the presences of a sloping land surface. As Prof. Ataie‐Ashtiani points out, the absence of a tidal overheight in the case of a confined aquifer makes that the difference in the model outcomes for a specified head and a specified flux at the inland boundary will be less pronounced than for an unconfined aquifer.
