摘要

This paper presents an analytical solution of groundwater head response to dual-tide fluctuation in an island leaky aquifer system. This system comprises a confined aquifer and a semipermeable layer (the confined aquifer's roof), Both the confined aquifer and its roof terminate at the both coastlines. The analytical solution indicates that the head fluctuation decreases with the vertical leakage, the aquifer's length and storativity, and increases with the aquifer's transmissivity. A threshold value of the aquifer's length is defined.
