Using a SIMD-optimized broadband parabolic equation propagation model in a range- dependent waveguide, the extended boundary condition model for object scattering, and a new method for coupling the two models, broadband basin-scale active acoustic simulations are possible. Preliminary results and reference solutions generated using a finite difference time domain method are presented.
