Image-based measurements of degree of saturation
A method based on SWIR images is proposed for measuring the degree of saturation in soils. This method is especially suitable for use in experiments conducted in the facilities of a common geotechnical laboratory. The method uses images on the short-wave infrared (SWIR) (wavelength: 1400– 1550 nm), which is highly absorbed by water compared with the other bands of the light spectrum (visible and near-infrared). The paper presents the basis of the method and the procedure to measure the degree of saturation in a massive and non-invasive way. A relation curve to transform the pixel intensity values to the degree of saturation is provided for samples of a beach sand. The non-linearity of this curve is discussed and related to the optical path length.
