- Abstract
- A detailed understanding of the flow and transport processes of chemicals in soils is needed to implement effective and efficient soil and water management strategies and to meet the current challenges of sustainable development. The solute transport process is a key process determining the mass flow of chemical substances once they are released in the soil solution. The transport process is a highly nonlinear and space-time dynamic process for which models are still poorly validated at the larger scale. In this article, we review some recent advances in describing solute transport in soil at the macroscopic core scale, corresponding to the scale of most soil measurement devices, and the pedon scale, corresponding to the scale of a small field. After introducing basic concepts, major problems using the classical Convection Dispersion Equation (CDE) model for describing field-scale solute transport is presented and alternative modeling concepts are introduced.
