An Investigation on the Effect of Prevailing Winds upon the Depth of Bays. (4th Paper)

[摘要] In the present paper, the author shows the result of application of the method of investigation explained in the previous papers to Beppu Bay in Kyûsyû, the depth of which seems to have been affected by the deposition of sand and mud discharged by rivers, etc. as well as by winds. The following results were obtained, viz.(1) There exists a more or less close parallelism between Δ (s) curve representing the depth distribution of the bay along the coast, and f (s)-or Φ (s) curve representing the effect of prevailing winds.(2) The parallelism seems to be somewhat closer between the curves Δ (s) and f (s) than between the curves Δ (s) and Φ (s).(3) It seems that the phase of undulation of Δ (s) curve is somewhat different from that of f (s)- or Φ (s) curve. A possible explanation was made for this difference in phase.(4) More or less conspicuous anomalies appear here and there in the “Anomaly curve” of this bay.A more detailed discussion will appear in a future number of the “Geophysical Magazine”.
