Pavlovskii's method is applied to Dupuit's approximate solution of steady hydraulic flow of unconfined two‐dimensional plane or curved aquifers in uniform or nonuniform soils, on a horizontal or inclined impervious base. Graphs correlate the geometrical parameters. The error on the potential is about ¼%. The effect of end slopes, especially of the seepage face, may account for some 30% of the total discharge. In one‐dimensional flow the discharge is correct even in nonuniform and curving aquifers on a horizontal base and seemingly also on an inclined base. Girinskii's potential in nonuniform soils in Dupuit's approximation is replaced in the exact theory by two other potentials. (Key words: Groundwater; seepage; hydraulics)
