Summary
An investigation of the downward transport of a solute following a series of alternating irrigation/rainfall and evapotranspiration events is carried out. The principle of conservation of mass, and the concepts of partition chromatography are used in constructing a simple model which enables the peak solute concentration depth to be calculated at any particular time given the rainfall and evapotranspiration history. Prediction of the theory is compared with published data on solute transport.
