Based on exact dynamic-stiffness matrices and Green’s functions of a layered saturated soil, the scattering of SV waves by a canyon of arbitrary shape in a saturated layered half-space is modeled using the indirect boundary element method in frequency domain. The results of the saturated sites are compared with that of corresponding dry layered site. It is shown that the incident angle, the frequency of incident wave and penetrability of soils have a great effect on displacements. The incident angle and frequency of incident wave should be comprehensively considered in dynamic analysis of the saturated sites
