＜Introduction＞ This manual explains how to use the web-site “Kurushima Kaikyo Tidal Current

Information”. This web-site displays the prediction of tidal current in Kurushima Kaikyo on arbitrary

time. The prediction estimated from analytical result of tidal simulation is sometimes

different from the actual currents which influenced with sea and weather conditions. < Necessary version of OS and Web-browser software >
