%X Dye tracer has been widely used in sandbox experiments of solute transport.This study uses image analysis to determine the concentration of dye tracer in porous media.By establishing a quantitative relationship between the concentration and the hue value of the dye tracer,the concentration distribution of the dye tracer can be quickly obtained.The image analysis provides a cost-effective and high-resolution method to quantify the solute concentration distribution in two-dimensional sandbox experiment for groundwater solute transport studies.Because the range of image hue values is limited,the image analysis method can only be applied to a certain range of solute concentration.
