Abstract
The response of a confined well-aquifer system to tidal dilatations requires consideration of the earth tidal dilatation and the ocean tide dilatation. For wells located near the ocean the explanation of tides requires analysis of at least two tidal harmonic constituents and the ratio of the heights of the corresponding ocean tide constituents. The magnitudes of the ocean tide dilatations can be eliminated in solving the simultaneous equations, but their ratio must be known. Tides observed in ten wells in Virginia were satisfactorily explained using modifications of the equations, observed barometric and ocean tide data, and reasonable values for the porosity and bulk modulus of the aquifer system.
