Laboratory simulation of LNAPL spills and remediation in unsaturated porous media using the image analysis technique: a review

Leaking from underground storage and surface spills of hydrocarbon sources can cause serious nonaqueous phase liquid (NAPL) contamination in subsurface environments. The toxic compounds of chemicals have made field study impracticable and it has been replaced by laboratory and numerical simulations....
