Investigation of the Influence of Particle Size on the Migration of DNAPL in Unsaturated Sand

Four experimentswere conducted to investigate the migration of dense non-aqueous phase liquid (DNAPL) in unsaturated porous media using Light Reflection Method (LRM). The porous media was natural sand collected from a river and segregated into different sizes through sieving. Three different sizes o...
