摘要
In this paper, general models characterizing the decay of hydraulic conductivity with depth are given for porous media and fractured media, respectively. It is found out that the general models can be simplified by the exponential decay model under certain conditions and the decay exponent is convenient for describing the decay rate of hydraulic conductivity. Using this simplified model, the regularity of decay in hydraulic conductivity with depth in several aquifers with different depths of hydraulic conductivity measurements and lithology from different places around the world is analyzed.
