Effect of hydraulic conductivity probability distribution function on simulated solute leaching
In this paper, the effect of fitting several different probability‐distribution functions to hydraulic conductivity or pore‐water velocity values, in the simulation of the movement of a nonreactive solute through the soil, is evaluated. The simulation of solute transport in the soil was found to be sensitive to the distribution fitted to pore‐water velocity. The log‐Gaussian (log‐normal) distribution, though traditionally used, is not necessarily the best distribution for characterizing the spatial variability of saturated hydraulic conductivity, pore‐water velocity, or infiltrability. The upper tails of the simulated relative concentration series are best fitted by beta distributions, regardless of the input distribution used for pore‐water velocity.
