In the theory of coastal ground water in shallow strata the shore line, the contact line of the sea and the land surfaces, is usually assumed to be stationary. However, when a sea beach is sloped, the shore line moves to and fro according to the rise and fall of the tide. In this paper, the authors present a theory including the effect of the moving boundary on the coastal ground water tide which is often encountered in the lowland along the Japanese coast. It is proved by this theory that the effect of the moving boundary due to the sea tide is found in the amplification of the fundamental oscillation of coastal ground water and in the occurence of third harmonic in ground water tide.This theory explains the particular ground water tide of the Miho Peninsula, a sand spit protruding into Suruga Bay, on the Pacific coast of Japan.
