The study of infiltration within the field of hydrology rests heavily on Richards equation, which, since its introduction in 1931 for infiltration in unsaturated soil, has had many solutions under particular sets of parameter constraints. There has also been numerical solutions that were verified with experimental data. Like many other differential equations in various fields of study, there is a preference for numerical solutions. Notwithstanding their utility, the reliance on numerical techniques often obscures the requirement of mathematical rigor and proof of corresponding analytic solutions. This research seeks to explore existing analytic solutions, under various parameter constraints, for the Richards equation. The approach adopted in this study is that of review of literature and mathematical formulation. Equations will be investigated in a sequential order from many to just a few constraints. The researcher expects to present detailed analytic solutions.
