| Outline of Final Research Achievements |
In this study, by selectively using geophones for exposed ground and hydrophones for submerged ground, the scope of application of MASW (Multi-channel Analysis of Surface Waves) technology was extended when the subsoils of tidalflat/ shallow sea is surveyed. By combining these technologies and simplified sampling and sounding technologies, an integrated and packaged ground survey method is proposed. Using this method, we successfully restored the sedimentation history of the complex subsoil layers in an estuary or an artificial tidalflat. These results can contribute to the interdisciplinary fields of geophysics, coastal engineering, coastal ecology, and geotechnical engineering.
