This document attempts to provide a set of water infiltration models which have the flexibility of handling a wide variety of hydrogeologic, soil, and climate scenarios. More specifically, the purposes of this document are to: (1) categorize infilteration models presented based on their intended use; (2) provide a conceptualized scenaro for each infiltration model that includes assumptions, limitations, boundary conditions, and application; (3) provide guidance for model selection for site-specific scenarios; (4) provide a discussion of input parameter estimation; (5) present example application scenarios for each model; and, (6) provide a demonstration of sensitivity analysis for selected input parameters. Six example scenarios were chosen as illustrations for applications of the infiltration models with one scenario for each model. The intention of these scenarios is to provide applications guidance to users for these models to various field conditions. Each model application scenario includes the problem setup, conceptual model, input parameters, and results and discussion.
