     the three finite-element, finite-difference and finite-volume numerical methods for hydrodynamic modeling of different water situations are based on solving the governing differential equations on the modeling domain grids. in general, a grid is a partition of a domain into sub-domains or subdivisions. this process of subdivision is called grid generation. although generating a denser grid often leads to a higher resolution of the modeling system in expense of higher computational cost, this is not always the case, and thus, we have to use an optimized grid for the domain to ensure the efficiency of the modeling process (berg et al., 1997). in this research work, hydrodynamic modeling of weser river estuary, located at german north sea coast, has been carried out by considering different number of nodes and triangular elements in a finite element approach using the swevolver and xf4 software packages (2-d hydrodynamics swevolver manual, 2004; xf4 manual, 1999). then, the modeling results have been compared together to obtain an optimized grid for the area, in which a new harbor place for container ships should be designed based on the results.
