A Generalized Absorbing Boundary Condition for Elliptic Harbor Wave Models

Conventional absorbing boundary conditions used in elliptic harbor wave models usually do not consider the effect of incident angle and amplitude variation of the outgoing waves at a boundary. In this paper, a generalized absorbing boundary condition with linear approximation is developed to account for these effects. Improved solutions have been obtained using the new boundary condition in three test cases that show little spurious boundary reflections. The proposed boundary condition increases the reliability of model predictions for complex real-world applications.
