Comparison of SCS and Green-Ampt Distributed Models for Flood Modelling in a Small Cultivated Catchment in Senegal [PDF]
Geosciences, 2018 The vulnerability to floods in Africa has increased over the last decades, together with a modification of land cover as urbanized areas are increasing, agricultural practices are changing, and deforestation is increasing.

Optimal parameters for the Green-Ampt infiltration model under rainfall conditions [PDF]
Journal of Hydrology and Hydromechanics, 2015 The Green-Ampt (GA) model is widely used in hydrologic studies as a simple, physically-based method to estimate infiltration processes. The accuracy of the model for applications under rainfall conditions (as opposed to initially ponded situations) has ...

A green-Ampt model considering unsaturated zone and pore air pressure
GeodermaThe relationship between infiltration time and the depth of the wetting front can be solved using Darcy’s law. According to this, the infiltration rate is equal to the derivative of the infiltration amount regarding time.

Modified Green-Ampt model for infiltration analysis in loess area and its parameter determination and verification [PDF]
Scientific ReportsWater infiltration into soil is important in geotechnical engineering. The classical Green-Ampt (GA) infiltration model is widely used in soil infiltration due to its physical significance, but it ignores the actual unsaturated layer in the infiltration ...

3DMGAR: A Transient Quasi-3D Point-Source Green–Ampt Infiltration and Redistribution Model
Vadose Zone Journal, 2018 Although Richards’ equation (RE) generally provides a good description of infiltration and water redistribution in soils, its numerical solutions can be computationally intensive or suffer from numerical instability and require extensive soil data ...

Green‐Ampt infiltration model for sloping surfaces [PDF]
Water Resources Research, 2006 This work quantifies and explains the direct physical effects of slope angle on infiltration and runoff generation by extending the Green‐Ampt equation onto sloping surfaces. A new extended solution using identical precipitation hydrographs was compared to the original formulation and then used to calculate the infiltration and runoff generation for ...
