Green and ampt infiltration model
Web2 days ago · The Green-Ampt model estimates the soil infiltration of rainfall, assuming that the rainfall intensity is higher than the infiltration capacity. As shown in Figure 1 , the Green-Ampt model considers that the rainfall infiltrates the soil surface, generating a boundary called wetting front, separating the wetted soil from the dry soil. WebJan 29, 2024 · An alternative model set-up was considered, with the Green-Ampt model for infiltration. As for the SCS model, the Green-Ampt parameters were either preset or …
