Abstract

Twenty-records of current velocity were obtained at two coastal stations in the Seto Inland sea. It was observed that water movement was characterized by east-west flow and north-south flow. Autocorrelation analysis showed that the characteristics of water motion were periodic in semidiurnal period. At frequencies about 2 cycles per day where power spectrum of current velocity had slopes of -5/3, the horizontal eddy viscosity coefficient were about 1.8x104 cm2/sec in east-west component and about 1.2x104 cm2/sec in north component.
