Abstract
This study is a sub-study of the
integrated research program “A forecasting
system of water elevations around Taiwan”.
One of the purposes of this study is to
develop a new storm surge model by
considering the local boundary effects.
Besides, it establishes and offers the
boundary-fitted orthogonal grid systems for
another two sub-studies of this program.
The study first introduces the FEMA
storm surge model developed by the Federal
Emergency Management Agency, U. S. A.,
and further improves the model theoretically
and numerically by replacing the original grid
system with the boundary-fitted grid system.
Meanwhile, newer viewpoints about the
singularity problems in BIEM are discussed.
Finally, a new numerical scheme is
established in this storm surge model to
improve the computational efficiency and
stability.
