Abstract

Summary

Groundwater flow is one of the most important topics in water resource and agriculture. Most alluvial stratum consisted of heterogeneous sedimentary deposits has a different depositional structure. Because of depositional processes, the groundwater flow greatly influence the orientation of underground medium, which further affect the radial anisotropy of underground medium, and change the SH- or (and) SV- wave velocities. We propose to use radial anisotropy estimated by surface waves to detect ground water flow. SH- and SV-wave velocities are obtained from Love waves and Rayleigh waves acquired along the same survey line, respectively. By analyzing the radial anisotropy, we can detect the direction of ground water flow as well as the depth of it. Two field tests are performed at two different sites, both of which prove the feasibility of detecting groundwater flow by analyzing radial anisotropy.
