An analytical solution is developed for seepage through a hillside in which a curved water table is maintained by steady percolating water. The two‐dimensional surface is assumed to be a straight slope from the base to a seepage point but may be irregular at higher elevations. Conformal transformations are used to determine seepage elevations and water table profiles as a function of the seepage rate and the slope. For small slopes and small percolation rates the seepage elevation is equal to the rainfall rate times the width of the slope divided by the saturated hydraulic conductivity.
