Phosphorus (P) loss from agricultural fields and watersheds has been an important water
quality issue for decades because of the critical role P plays in eutrophication. Historically …

This review discusses the causes and consequences of 'non‐equilibrium'water flow and
solute transport in large structural pores or macropores (root and earthworm channels …

Understanding groundwater recharge is essential for successful management of water
resources and modeling fluid and contaminant transport within the subsurface. This book …

Preferential flow, a major influence in unsaturated soil and rock almost everywhere, occurs
by multiple phenomenologically distinct hydraulic processes. For the mode known as …

Preferential flow (PF) in soil has both environmental and human health implications since it
favours contaminant transport to groundwater without interaction with the chemically and …

Subsurface drainage is a beneficial water management practice in poorly drained soils but
may also contribute substantial nitrate N loads to surface waters. This paper summarizes …

Land cover is considered to have significant influence on the hydrologic response of a river
basin. In this study, we assessed how changes in land cover over time affected flood …

Agricultural phosphorus (P) losses to surface water bodies remain a global eutrophication
concern, despite the application of conservation practices on farm fields. Although it is …

This report reviews and summarizes findings from more than 30 North American studies of
pesticide transport into subsurface agricultural drains. Background information about …

Macropores formed by the root systems of woody shrubs may be an important conduit for
downward water movement in desert soils. An experiment with 32 1· 0-m2plots, 16 with a …
