The influence of the net rainfall mixed Curve Number – Green Ampt procedure in flood hazard mapping: a case study in Central Italy [PDF]

Journal of Agricultural Engineering, 2013
A net rainfall estimation procedure, referred to as Curve-Number For Green-Ampt (CN4GA), combining the Soil Conservation Service - Curve Number (SCS-CN) method and the Green and Ampt (GA) infiltration equation was recently developed, aiming to distribute

Comparison of SCS and Green-Ampt Distributed Models for Flood Modelling in a Small Cultivated Catchment in Senegal

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.

Infiltration and stability analysis of gravelly soil slopes under rainfall with the improved green-ampt model [PDF]

Frontiers in Earth Science
Rainfall infiltration is a key cause of slope instability, especially in complex soil-rock mixture slopes with preferential flow paths. The classic Green-Ampt model, widely used in infiltration studies, has limitations in handling air pressure variations

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 ...

Analysis Result of Downward Infiltration Experiments Using the Modified Green Ampt Model

, 2022
The excel "Analysis result of exprement.xlsx" collects the analysis result of downward infiltration experiments using Modified Green Ampt Model (MGAM). The MGAM is built based on the study by Hsu, S.-Y., & Hilpert, M. (2011).

Green-Ampt approximations [PDF]

, 2005
The solution to the Green and Ampt infiltration equation is expressible in terms of the Lambert W-1 function. Approximations for Green and Ampt infiltration are thus derivable from approximations for the W-1 function and vice versa. An infinite family of

Improved calibration of the Green–Ampt infiltration module in the EROSION-2D/3D model using a rainfall-runoff experiment database [PDF]

SOIL, 2021
Soil infiltration is one of the key factors that has an influence on soil erosion caused by rainfall. Therefore, a well-represented infiltration process is a necessary precondition for successful soil erosion modelling.

Modification of Green-Ampt model based on the stratification hypothesis

Shui kexue jinzhan, 2012
A modification of Green-Ampt model is proposed based on the stratification hypothesis,which dynamically divided the soil column is into saturated layer,transient layer and dry layer.The model uses the concept of an equivalent hydraulic conductivity in ...
