Abstract

Example embodiments relate to a computer-implemented method for determining water content of a moist sample of porous material from a spectral reflectance spectrum of the moist sample. The computer-implemented method comprising: obtaining (201) a hyperspectral measurement of the moist sample comprising the spectral reflectance spectrum (212), and a spectral response function (211) associated with the hyperspectral measurement; determining (202) a water-layer thickness (215) within the moist sample based on the spectral response function, the spectral reflectance spectrum of the moist sample, a spectral reflectance spectrum of an air-dried sample of the porous material, and an absorption spectrum of water; and determining (204) the water content of the moist sample (221) according to a first predetermined relationship (220) or a second predetermined relationship (230) based on (203) the water-layer thickness within the moist sample.
