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

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

Modeling of Infiltration from An Artificial Recharge Basin with a Decreasing Ponded Depth

Journal of King Saud University: Engineering Sciences, 1991
The first important physical process in basin recharge is the infiltration of water from the basin's bed to the water table below. The Green and Ampt approach was applied to model infiltration from an artificial recharge basin with a decreasing ponded ...

Building Treatment and Its Effects on City‐Scale Urban Flood Modeling

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT Physics‐based flood hydrodynamic models are widely used for predicting inundation in urban basins with complex building layouts. While the treatment of urban buildings in these models has been extensively discussed, over‐assumptions can introduce inaccuracies, uncertainties, and excessive computational effort, particularly under data‐scarce ...

Self-adaptive Green-Ampt infiltration parameters obtained from measured moisture processes

Water Science and Engineering, 2016
The Green-Ampt (G-A) infiltration model (i.e., the G-A model) is often used to characterize the infiltration process in hydrology. The parameters of the G-A model are critical in applications for the prediction of infiltration and associated rainfall ...

Calibración de parámetros de un modelo de infiltración en la cuenca alta del arroyo Pergamino [PDF]

Ciencia del Suelo
La infiltración regula el escurrimiento superficial y como consecuencia los procesos de erosión y contaminación. Existen diferentes ecuaciones de infiltración, siendo la de Green Ampt una de las más utilizadas en modelos hidrológicos y de erosión.

Optimal parameters for the Green-Ampt infiltration model under rainfall conditions

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 ...

Adequação dos parâmetros do modelo de Green-Ampt-Mein-Larson em condições de campo Adjustment of Green-Ampt-Mein-Larson model parameters under field conditions

Revista Brasileira de Engenharia Agrícola e Ambiental, 2010
O modelo de Green-Ampt-Mein-Larson (GAML) é um dos mais empregados na modelagem da infiltração; entretanto, alguns de seus parâmetros não condizem com a situação real do processo de infiltração da água no solo.

基于信息熵方法的土壤水分入渗方程试验研究

Shuitu Baochi Xuebao, 2017
对沙壤土、黏壤土进行水分入渗试验，确定4种熵方程（E-Horton、E-Kostiakov、E-Philip、E-Green-Ampt）系数并标定了一般方程（Horton、Kostiakov、Philip、Green-Ampt）系数。根据所得到的方程计算相应的入渗率，并与试验观测数据进行比较。结果表明：在沙壤土中，E-Horton、E-Kostiakov、E-Philip方程能较好地反映土壤水分入渗规律，E-Green-Ampt方程高估了土壤水分入渗率。在黏壤土中，4种熵方程拟合效果均较差 ...

Analysis of rainfall infiltration based on the improved Green-Ampt model with permeability coefficient correction

Shuiwen dizhi gongcheng dizhi
The classical Green-Ampt model assumes that the wetting zone is completely saturated when analyzing the rainfall infiltration law of the shallow slope, without considering the infiltration transition zone and its influence on the permeability coefficient

Tipikal Kuantitas Infiltrasi Menurut Karakteristik Lahan (Kajian Empirik di DAS Cimanuk Bagian Hulu)

Forum Geografi, 2009
Rate of infiltrate can be conduct as function of permeability, suction head and moisture of soil parameter. The parameters have close relationship with soil physical characteristics. That relation can be formulated by empirical research.
