Increasing groundwater contamination across the globe triggered the concept of “aquifer
vulnerability”, which has been extensively used worldwide during past three to four decades …

The original review of macropores and water flow in soils by Beven and Germann is now 30
years old and has become one of the most highly cited papers in hydrology. This paper …

Recently, the interactions between soil structure and microbes have been associated with
water transport, retention and preferential or column flow development. Of particular …

The mechanisms allowing the rapid release of stored water to streams are poorly
understood. Here we use a tile-drained field site to combine macroporous soils at the …

Atrazine, one of the most widely used herbicides in the world, threatens human health along
with terrestrial and aquatic biota. Recent reports have found atrazine in drinking water to be …

We quantified unsaturated flow beneath playa and adjacent interplaya settings at a site in
the Southern High Plains (United States) to resolve issues related to where and how water …

Although both raindrop driven processes and diffusion play important roles in the transfer of
chemicals from soil to surface runoff, current transport models either do not consider the two …

This study was undertaken to determine the present distribution and mobility of sludge-
applied metals at an old land application site. Trace metals concentrations were determined …

In most contaminant transport modeling studies, only the macropores that are visible at the
soil surface are considered. Furthermore, it is assumed that these macropores are straight …

Agricultural subsurface drains, commonly referred to as tile drains, are potentially significant
pathways for the movement of fertilizers and pesticides to streams and ditches in much of the …
