By using the parabolic equation for range-dependent waveguide propagation, the extended boundary condition model for object scattering, and a new method for coupling the two models, basin-scale active acoustic simulations have been performed. The transformations and algorithms, as well as some results, will be presented. [Work supported by ONR.]
