been made either with a model for perfectly confined aquifers or with a model for purely
unconfined aquifers. However, many aquifers may be neither totally confined nor purely
unconfined at the frequencies of tidal loading but behave somewhere between the two end‐
members. Here we present a more general model for the tidal response of groundwater in
aquifers with both horizontal flow and vertical leakage. The model has three independent …
