Abstract
All soils by definition have soil layers/horizons. Characteristic properties of soil horizons have been shown to influence water and solute flux. It is usually assumed that soil horizons can be represented by independent layers and that their behaviors can be linearly combined and predicted by convolution of the independent transport solutions of each layer. However, studies suggest that correlation length scales of transport are interrupted at horizon boundaries or the boundary influences significantly the nature of transport in the subsequent layer. Understanding and accurately modeling flow and transport across soil layers requires adequate information about very local scale transport properties and thus, measurements with sufficiently high spatial and temporal resolution which is a challenge in field studies. This paper presents a method of measuring local soil water flux and solute transport within and across soil layers using vertically installed TDR probes. Implications of the measurements as they relate to understanding spatially scale dependent water and solute transport are discussed.
