Infiltration per unit area of the source region from discs, strips and furrows has previously been shown to be the sum of the one-dimensional infiltration and an edge effect term. Here we apply the same approach to examine infiltration under a constant head from boreholes (both lined and unlined). A critical empirical parameter (γ) in the edge effect term is related to the radius of the borehole, soil hydraulic properties, boundary and initial conditions. For lined boreholes, γ has a narrow range and for the examples investigated, a constant value of 1.06 introduces less than 5% error compared to using the case-specific γ value. For unlined boreholes, γ is larger, ranging between 1.02 and 3.16 for the examples investigated, and should be estimated for specific conditions.
