This type of flow exists at the wastewater treatment facility at Tuscola, Illinois, where it is used to augment a central-pivot sprinkler system of wastewater treatment. Boundary Modeling of steady infiltration through a homogeneous soil to drains was compared with three closed-form equations: Kirkham, Hooghoudt, and Hammad. For water table depth at the midpoint between drains, Boundary Modeling predicted results virtually identical to Hooghoudt's. For the water table depth at the drain, the differences between Boundary Modeling and Hammad's prediction are all less than 2 cm, averaging 0.3 cm. The mass balance error for these solutions was less than 0.14% for the 32 simulation cases examined. The utility of the Boundary Method (BM) was demonstrated by determining hydraulic head and stream functions in problems of subirrigation, drainage, and evaporation in homogeneous soils and problems of subirrigation and drainage in zoned soils. In order to apply the Boundary Method to wastewater treatment and to determine dispersion and average residence time of the sewage effluent in the field, a steady chemical transport experiment for disturbed soils was conducted out under managed field conditions. BM solutions of hydraulic head differed from measured values by 0.2 to 6.2 cm. Modelled arrival time of bromide was essentially identical to measured values and peak concentration of bromide was within 0.1 mg/l at all measured locations.
