Abstract
Variabilities of hydraulic and solute transport properties of soi1 are examined at three scales: pore-scale, sample volume-scale, and field-scale. Undisturbed soil cores were taken at 19 subsites spaced logarithmically along a 150 m line transect in a Groseclose mapping unit near Blacksburg; Virginia. Three core sizes were taken at each subsite at the soil surface and 0.5 m depth. 'Small' cores were-40x54 mm; 'medium' cores were 60X100 mm; and 'large' cores were 100x150 mm. Macropore effects on solute transport
were evaluated using monocontinuum and bicontinuum models. Bicontinuum-predicted solute breakthrough curves
(BTC) closely agreed with observed BTC data with mean errors of reduced concentrations
