This has been recognized and Green and Ampt has been made available for use in EPA’s Stormwater Management Model (SWMM) for storage basin nodes, which can be used to model SCMs. However, the Green and Ampt model used for watersheds has two major shortcomings when WebScholarWorks at Montana State University (MSU)

Webmethod for modeling infi ltration and soil water redistribution that could be translated to a variety of hydrologic modeling applications. Infi ltra on and Redistribu on Calcula ons Green–Ampt Infi ltra on with Redistribu on Method Th e Green and Ampt (1911) equation describes the infi l-tration process under ponded conditions. Infiltration is a component of the general mass balance hydrologic budget. There are several ways to estimate the volume and/or the rate of infiltration of water into a soil. The rigorous standard that fully couples groundwater to surface water through a non-homogeneous soil is the numerical solution of Richards' equation. A newer method that allows 1-D groundwater and surface water coupling in homogeneous soil layers, and that is related to the Richards equation is the Finite w… WebThe simple method of solving the Green-Ampt one-dimensional infiltration equations developed from Darcy's law are proposed for practical applications.
