Water‐table elevations in some pacific coast beaches

Abstract

The University of California in cooperation with the Bureau of Ships, United States Navy, has been engaged in field investigations of beach and surf conditions at many of the more important beaches of the West Coast of the United States. One of the first problems encountered in these studies was that of establishing a datum on each beach which would be related to the tidal datum (Meat lower low water) without running long lines of levels from points of known elevation. In an effort to discover a simple way of determining this datum, investigations were initiated, by means of which it was hoped to be able to connect, empirically, the elevation of the ground water in the teach with the predicted tide. Although the original purpose did not prove practicable, considerable interesting data have been obtained. It is the purpose of this paper to present some of these data for the benefit of other investigators.
