Geophysical Surveys for Assessing Levee Foundation Conditions, Feather River Levees, Marysville/Yuba City, California

Abstract

Effective flood and coastal storm emergency response depends on the ability of emergency managers to obtain information on the condition of flood-damage reduction structures in near real-time. This report describes the results of a geophysical study performed to determine the potential for geophysical methods to provide supplemental geologic data between existing soil borings in a rapid fashion in an area of complex geology. The geophysical study was conducted along 10 km of landside levee toe adjacent to the Feather River, approximately 5 km south of Marysville/Yuba City, CA. Electromagnetic induction, capacitively coupled electrical resistivity, and direct current electrical resistivity survey methods were used to conduct the geophysical study. Survey results were used to classify soil type to depths of approximately 60 m.
