[Abstract]

　The currents and mass transports in the Arabian Gulf are investigated with analysis of the oceanographic data and numerical models. According to the seasonal variation of sea water temperature and salinity, It is found that sea waters of high salinity in the inner part of the gulf, which is produced by the extreme evaporation in winter season, sinks and flows out to the Strait of Hormuz in as a bottom current. With numerical models, we simulate 2-amphidromic system of semi-diurnal tides and 1-amphidromic system of diurnal tides. And also we calculate the wind-driven currents of both a stratified sea and a vertically well-mixed sea.
　Using the wind-driven currents and tidal currents calculated numerically reffered to above, we construct a system to calculate the drift of floating materials. This program is designed to work in a notebook-type personal computer, so as to be able to calculate the path of the floating materials, including oil, in anywhere.
