“…Useful regional and nationwide inferences have been reported and widely used. After examination of 271 soil horizons beneath topsoil in two US regions, O'Neal [70,71] suggested a set of field clues that could serve as the keys to place soil horizon into one of the seven permeability classes. The principal clues were relative dimensions of structural aggregates, amount and direction of the aggregate overlap, number of visible pores and texture.…”

Integrative studies are needed as the response to mounting environmental challenges. The new discipline-hydropedology-has been defined as an intertwined branch of soil science and hydrology that encompasses the multiscale basis and applied research of interactive and hydrologic processes and their properties in the unsaturated zone. This review focuses on the relationship between soil structure and soil hydraulic functions at different scales, which is the distinct focus of hydropedology that makes it a desirable development for its parent disciplines. Status and perspectives are reviewed for revealing relationships between hydrologic functions of soils and soil structure at the aggregate/ped scale, the horizon/pedon scale, the field/hillslope scale and the watershed/basin scale. Transcending scales can be achieved by acknowledging that relationships between soil structure and hydrologic functioning at a particular scale are controlled by such relationships at a finer scale and greatly influenced by those at a coarser scale. Addressing soil hydrologic functioning at societally important scales can be achieved by applying data fusion, pedotransfer relationships, and concurrent use of models. Hydropedology emerges as the logical consequence of the progress in science and as the timely response to society's needs.

“…The aggregate system approach may well be appropriate for Ap horizons, but it ignores or subjugates B horizon morphological structure to a very minor role in soil importance. The aggregate approach neglects the very important impact that the interped zone has on root growth and water and air movement in soils (Bouma, 1991; Coen and Wang, 1989; O'Neal, 1949). In this regard, recent soil permeability work has centered on macropore flow in soils.…”

“…Among the studies that address estimation of hydraulic conductivity from related properties are O'Neal (1949;, Uhland and O'Neal (1951), Hirschi and Moore (1980), Rawls et al (1982), McKeague et al (1982), Puckett et al (1985), Wang et al (1985), Bouma (1986), and Baumer et al (1987).…”
