Simulation of solute transport using a transfer function model

Simulation of solute transport using a transfer function model A transfer function model is proposed for simulating solute transport under natural field conditions where substantial variability exists in water transport properties. This approach makes no attempt to describe the variability through a deterministic model but merely measures the distribution of solute travel times from the soil surface to a reference depth. Using this distribution function, it is possible to simulate the average solute concentrations at any depth and time for arbitrary solute inputs or water application variability. Equivalently, the model may be used to predict the probability of extremely long or short travel times for a mobile chemical.

Abstract

A transfer function model is proposed for simulating solute transport under natural field conditions where substantial variability exists in water transport properties. This approach makes no attempt to describe the variability through a deterministic model but merely measures the distribution of solute travel times from the soil surface to a reference depth. Using this distribution function, it is possible to simulate the average solute concentrations at any depth and time for arbitrary solute inputs or water application variability. Equivalently, the model may be used to predict the probability of extremely long or short travel times for a mobile chemical. In this paper several illustrative calculations are performed for which analytic solutions are possible. In a companion paper (Jury et al., this issue) a field test of the model is reported.
