Integrated geological and geophysical investigations of a levee system damaged by the East Japan Earthquake: A case around Yoshinuma Sluiceway, Kokai River.

Abstract Integrated geophysical surveying was conducted along a levee system which had been damaged by the 2011 East Japan Earthquake. High-resolution surface wave survey using Land Streamer, capacitively coupled resistivity survey using OhmMapper, slingram EM survey using GEM-2, and DC resistivity survey were applied for the integrated survey. 250-m long two parallel lines were set along the levee
