A QUASI-3D NUMERICAL SIMULATION FOR HYDRODYNAMIC CIRCULATION IN TOKYO BAY USING CIP-FEM

Abstract

We developed a numerical quasi-3D hydrodynamic model using CIP-FEM to evaluate the enclosed coastal environments. The model was applied to Tokyo Bay to investigate its performance and usefulness. The calculated profiles of salinity and water temperature agree well with the observed ones. These results show that the validity of the proposed model was confirmed, and the improvements of the solving method for the advection term made progress toward the accuracy of the vertical profiles in the surface layer. We discussed a relationship between wind conditions and clockwise/counterclockwise circulation in the upper and middle layer using the proposed model.
