An Investigation on the Effect of Prevailing Winds on the Depth of Bays. (Ist Paper)

[摘要] It is a well established fact that when winds blow from the offing towards the coast or from the coast out to the offing a vertical circulation of water is produced, and it follows as a natural consequence that the depth of shallow seas or bays may change. In this paper, is treated this subject in case of bays of moderate size, in which the effect of tidal and oceanic currents etc. is small. In Part I a discussion is made on the movement of sand particles at the bottom of a bay. The method of treatment of the subject is dwelled on in Part II, where a provisory functional expression Φ (s) is introduced to represent the effect of prevailing winds on the depth of a bay, where s is the length along the coast line, and its application to an actual ease is shown in Part III. The result seems to justify this method.
