Simple perturbation methods continue to yield good results in the solution of the problem of vertical infiltration of water into unsaturated soils. The initial approximation is valid for all times and gives useful information about important flow characteristics. The required computations are always direct and simple. Some numerical work pertaining to Yolo light clay is presented to exhibit the advantages, relevance, and simplicity of the present analysis compared to other existing works on this topic.
