文摘

Quantitatively assess resistivity method by comparing with light transmission visualization. Resistivity method successfully monitors the migration of DNAPLs in slight heterogeneous media. Resistivity tomography based on smoothness consistently overestimates the area of plume. The resistivity increase caused by the low-saturation DNAPLs is slight.
