Subsurface Mapping with Airborne Electromagnetics in the Central Valley of California
Extensive pumping of groundwater has led to subsidence in parts of the Central Valley of California. Airborne electromagnetic data were acquired to assess the ability of the method to assist in understanding the spatial variation of the observed subsidence. A total of 104 km of data were acquired and the derived resistivity model related to subsurface lithology using 12 lithology logs from near-by wells. We were able to map the clay layers, within and between aquifers, that are the likely geologic controls on the observed subsidence.
