Hydraulic and morphologic heterogeneity in the soil environment contribute to the complexity of characterizing water and solute transport. The objective of this laboratory study was to investigate the effect of soil physical and hydraulic properties on the spatial variability of solute transport. Undisturbed blocks of Cecil soil (Clayey, kaolinitic, thermic Typic Kanhapludults) were collected from a interfluve, linear slope, and footslope. Soil blocks were placed on a grid lysimeter plate for water and solute collection. A single application of 400 mL of 1000 mg bromide (Br) L
