Nominal isovelocity sound speed. A full depth-dependent profile will be added in a future update.
Flat-bottom depth assumed for the entire scenario area. Used by the hybrid propagation model and future Lloyd's mirror effects.
Spherical: TL = 20 × log₁₀(range). Point source in unbounded medium. Appropriate for deep water or short ranges.
Cylindrical: TL = 10 × log₁₀(range). Surface/bottom-bounded waveguide. Appropriate for shallow water at long ranges.
Hybrid: Spherical spreading up to transition range rt = πD²/λ, then cylindrical beyond. Models the near-field to far-field transition in a shallow-water waveguide (D = ocean depth, λ = wavelength).
