東京湾モデルの潮流推定解析に対する拡張カルマンフィルタFEMの適用

抄録

In this study, we present the application of the extended Kalman filter FEM for tidal current estimation analysis in Tokyo bay. As for the governing equation, the non-linear shallow water equation introduced, and the Galerkin and the selective lumping methods are applied to discretize the governing equation in space and time. The observed water elevation are employed in the tidal current estimation analysis, and we examine about the effect of the introduction of the observed water elevation in tidal current estimation analysis.
