[MTT30-P06] Integrated Geophysical surveys in levee excavation sites on the Chitose river, Central Hokkaido
Keywords:Integrated Geophysical Survey, Levee Survey
The resistivity and Vs structures obtained by the surface surveys were verified by the resistivity and Vs distribution measured on the excavated slope surface. These surveys delineated imhomogeneity of soils in the levee and the basement. Comparing the resistivity and the grain size evaluated by soil tests, the resistivity structure identified a permeable zone in the levee and showed the extension to the basement.
