Warrick (his affiliation is not noted, though he thanks his students in his acknowledgments) has written a clearly organized text in advanced soil physics or vadose zone hydrology for use by students, researchers, and modelers who work with soil water flow, contaminant transport, and environmental pollution abatement. Mathematical development and analysis receive emphasis as the text describes the soil system, soil water flow, saturated flow, one-dimensional absorption, one-dimensional infiltration and vertical flow, multidimensional water flow in variably saturated soils, and solute and containment transport.
