EPA Infiltration Models

The United States Environmental Protection Agency (US EPA) developed a suite of numerical watershed infiltration process models available using MathCAD 6.0 spreadsheet model. Numerical infiltration models include, the SCS Curve number method, the Phillips 2 term model, the Layered Green Ampt Model, the Explicit Green Ampt Model, the Constant Flux Green Ampt Model, and the Infiltration/Exfiltration model.
