SPACIAL DISTRIBUTION OF SUSPENDED SUDIMENT WITH ADCP IN THE KESENNUMA BAY OSHIMA STRAIT

Abstract

 The purpose of this research is evaluation of 3 dimensional distributions of suspended particles with ADCP in and around Oshima Strait of Kesennuma Bay. The SS density was formulated based on a relation between rear scattering intensity of ADCP and FTU of water quality meter. Highest SS value was present above bottom west on the strait, and the current direction was west at mid-point of the strait. Transmitted SS to the west bay was up to ca. 200 g/sec, and ca. 50 % of the amount moved to the west bay mouth.
