This paper is concerned with transparent boundary conditions (TBCs) for wide angle "parabolic" equations (WAPEs) in the application to underwater acoustics (assuming cylindrical symmetry). Existing discretizations of these TBCs introduce slight numerical reflections at this artificial boundary and a
