N2 - The Simplified Image Analysis Method (SIAM) is a laboratory technique devised to assess the three-phase dynamic saturation of water and Non-Aqueous Phase Liquids (NAPLs) in granular soils. This method is based on an extension of the Beer-Lambert Law of Transmittance that establishes a linear relationship between the saturation of water (Sw), NAPL (So), and their corresponding average optical densities (Di), for pictures taken using two consumer-grade digital cameras attached to two band-pass filters (wavelengths λ = 450 and 640 nm). In this study, we use SIAM to characterize the migration of diesel (density ρ = 0.865 g/cm3, viscosity v = 7 mm2/s), a Light NAPL (LNAPL), when subject to different precipitation conditions (precipitation intensity i = 6.6 and 63.2mm/h) in a one-dimensional column (3.5 × 3.5 × 50cm) filled with Toyoura sand (particle density ρS = 2.65 g/cm3, equivalent grain size D60 = 0.196).
