Extension of a recent method for obtaining exact solutions of the Bruce and Klute equation
A recent method based on a specific power-law relationship between the matric potential head and the Boltzmann variable was presented by Prevedello et. al. (2008). Here, this relationship was generalized to a range of powers, and the solution extended to include the saturated zone. As a result, the new solution satisfies the Bruce and Klute equation exactly.
