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 series of geophysical investigations performed to determine the potential of geophysical methods to provide supplemental geologic data between existing borings in a rapid fashion in an area of complex geology located along the toe of the Sacramento River levees. The geophysical study was conducted along selected portions of the Sacramento River levee between Natomas Cross Canal and Powerline Road. Electromagnetic, ground penetrating radar and capacitively-coupled resistivity surveys were conducted to infer soil type.
