SPREADING OF OCEANIC MATERIALS WITH SECONDARY UNDULATIONS OF TIDE

Abstract

 Short-period oscllation flow often emerges in Maizuru Bay where tidal current is week and estuarine circulation is strong. The oscillation flow which has the 1-hour to 2-hours periods is due to the secondary undulations of tide, and is storng at the baymouth. This study shows that the numerical simulation can reproduce the oscillation flow by setting short-period elevation at the open boundary. Then, numerical experiments show the spreading oceanic materials differs among with or without the oscillation flow at the baymouth.
