Abstract In the present paper, it is pointed out that there are two catagories of adiabatic approximation. within the propagation distance the range-dependent variation of the waveguide may be accummulative (1) or nonaccummula-tive (2). The well-known criterion given by Milder is applicable for the first catagory. The criterion for the second catagory has been derived by the present authors. Two example are discussed, (1) a shallow water waveguide with slight surface roughness and (2) a shallow water waveguide with range-dependent sediment properties.
