Data assimilation is one of the effective solutions to avoid and to limit some of these errors. This manuscript evaluates how Ensemble Kalman filter, one of the most advance assimilation techniques, can enhance water elevation predictions in the Persian Gulf. The open source Delft3D FM was used as a hydrodynamic model and open source code of Open DA was employed to apply Kalman Filter. The Open DA was coupled inside the code of hydrodynamic model to improve its performance. We have setup several experiments to estimate the best number of groups, error parameter of observations, error parameter of open boundary, and the most effective station for assimilation. The results show that the data assimilation can effectively improve the hydrodynamic model results and can be used for real applications. }, URL = {http://joc.inio.ac.ir/article-1-1552-en.html}, eprint = {http://joc.inio.ac.ir/article-1-1552-en.pdf}, journal = {Journal of Oceanography}, doi = {10.52547/joc.10.40.85}, year = {2020} }
