A dual-porosity model for simulating the preferential movement of water and solutes in structured porous media
TL;DR: In this paper, a dual-porosity model was developed for the purpose of studying variably saturated water flow and solute transport in structured soils or fractured rocks, where water in both pore systems is assumed to be mobile.

How water moves in a water repellent sandy soil: 1. Potential and actual water repellency
Louis W. Dekker,Coen J. Ritsema +1 more
TL;DR: A distinction between potential and actual water repellency and the assessment of the critical soil water content is introduced and highlighted in this paper, where persistence and degree of dried samples were examined from 10 trenches in a dune sand with grass cover using the water drop penetration time and the alcohol percentage tests.
Journal ArticleDOI
Preferential flow in a sandy vadose zone: 1. Field observation
TL;DR: In this paper, the authors used dye tracing and profile excavation to examine water flow patterns in the unsaturated zone of the Central Sand Area of Wisconsin (CSAW), and found that preferential flow paths constituted the dominant flow pattern at this location.
Journal ArticleDOI
Water repellency in soils: a historical overview
TL;DR: Water repellency has been extensively studied in the literature as mentioned in this paper, with a large body of information available in a wide range of scientific disciplines throughout the world, especially in the United States and Australia.

Preferential flow descriptions for structured soils
TL;DR: In this paper, a number of various model approaches have been proposed to overcome the problem of preferential flow severely limiting the applicability of standard models for flow and transport that are mostly based on Richards' equation and convection-dispersion equation.
