Review and comparison of models for describing non-equilibrium and preferential flow and transport in the vadose zone
TL;DR: In this paper, a review of existing approaches for modeling preferential and non-equilibrium flow and transport in the vadose zone is presented, which range from relatively simplistic models to more complex physically based dual-porosity, dual-permeability, and multi-region type models.
Journal ArticleDOI

TL;DR: Key challenges in modeling soil processes are identified, including the systematic incorporation of heterogeneity and uncertainty, the integration of data and models, and strategies for effective integration of knowledge on physical, chemical, and biological soil processes.
Journal ArticleDOI
Modeling Nonequilibrium Flow and Transport Processes Using HYDRUS
TL;DR: A wide range of nonequilibrium water and transport modeling approaches available within the latest version of the HYDRUS-1D soŌ ware package are described in this paper, with a focus on the dual-permeability model.
Journal ArticleDOI
A review of model applications for structured soils: a) Water flow and tracer transport.
TL;DR: This review compiles results published over the past decade on the application of physically based models for simulating PF and PNE non-reactive tracer transport for scales ranging from the soil column to the catchment area.
