Wetland soils are dominated by anaerobic conditions induced by soil saturation and
flooding. This chapter reviews the chemical and physical parameters of soils, particularly …

This paper reviews the importance of large continuous openings (macropores) on water flow
in soils. The presence of macropores may lead to spatial concentrations of water flow …

Abstract Nitrate (NO 3−) leaching from agriculturalproduction systems is blamed for the
rising concentrations ofNO 3− in ground-and surface-waters around the world. This paper …

Principles of Soil Physics examines the impact of the physical, mechanical, and hydrological
properties and processes of soil on agricultural production, the environment, and …

Soil survey activities in many countries have reached a crucial phase. Standard country
wide surveys either have been completed or will be completed within the near future. This …

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 …

Flow pathways of water and solutes in soils form distinct patterns, which are not a priori
predictable. Macropore structure is a prime cause, but other factors, such as differing initial …

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

This paper gives a review of our current conceptual understanding of the basic processes of
water flow and chemical transport in the untsaturated (vadose) zone and of various …

The two major flow mechanisms in the vadose zone are uniform flow and preferential flow.
Both types of flow occur often simultaneously, but have considerably different consequences …
