A similarity solution exists in two-dimension when a constant flux is imposed along a line source. Following the R. R. Bruce and A. Klute method in one-dimension, this similarity solution can be used to determine the soil-water diffusivity. The application of the method is illustrated for a sandy loam. The advantage of the method is that the slope of the moisture profile is finite and easily measured, even close to the source.
