CHARACTERIZATION OF WATER DISPLACEMENT IN SOILS USING SIMPLE CHROMATOGRAPHIC THEORY

Abstract
Summary: Simple chromatographic equations were adapted to describe frontal water displacement by tracer‐containing water in soils where only partial displacement occurs. The equations were shown to give excellent agreement with experimental data in five field experiments where tracer was added in artificial rainfall. The consequences of partial displacement for soil water replenishment in the root zone, salt leaching and ground water recharge are discussed.
