Tide‐induced head fluctuations in a confined aquifer with sediment covering its outlet at the sea floor

A confined coastal aquifer usually extends under the sea for some distance with its submarine outlet covered by a thin layer of sediment with properties dissimilar from the aquifer. Previous theoretical studies neglected this outlet capping. In this paper an analytical solution is derived for a confined aquifer subject to tidal fluctuations with a leaky boundary condition at the outlet capping. For the cases that offshore length of the aquifer...
