Improved Green-Ampt infiltration model of soil slope considering inclination

Shuili Shuiyun Gongcheng Xuebao, 2020
In view of the fact that the traditional Green-Ampt infiltration model ignores the influence of slope angle and unsaturated zone of soil on the rainfall infiltration of slope, the gradient of infiltration potential energy of soil was modified by using ...

A comparison of discharge hydrograph using some methods of effective rainfall approach (case study: Upper Cisadane Watershed)

Jurnal Sumber Daya Air, 2016
Calculation of effective rainfall is an important step in hydrologic modelling. The used methods to calculate effective rainfall rarely observe watershed conditions on site.

Study on the influence of infiltration on flood propagation with different peak shape coefficients and duration

Water Policy, 2021
Traditional flood simulations fail to properly consider the impact of soil infiltration in floodplain areas with high soil infiltration rates. Notably, ignoring soil infiltration will lead to considerable uncertainty in flood simulations.

Discussion of “Application of a Nonstandard Explicit Integration to Solve Green and Ampt Infiltration Equation” by Damodhara R. Mailapalli, Wesley W. Wallender, Rajendra Singh, and Narendra S. Raghuwanshi [PDF]

, 2010
Mailapalli et al. (2009) presented an explicit numerical scheme for calculation of solutions to the 1D Green and Ampt (1911) infiltration equation. They compared their numerical solution to a numerical solution obtained using the Newton-Raphson method (e.

A green-Ampt model considering unsaturated zone and pore air pressure

Geoderma
The 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.

An improved Green-Ampt model for rainfall infiltration analysis of multi-layered heterogeneous soil slopes

Yantu gongcheng xuebao
The rainfall infiltration analysis of slopes is of a great significance to the reinforcement design, mitigation and risk mitigation of rainfall-induced landslides. The classical Green-Ampt model, whose parameters have clear physical meanings and which is

Rainfall infiltration model considering spatial variability of multiple layers in transition layer and its application in slope stability analysis

Yantu gongcheng xuebao
Establishing a reasonable rainfall infiltration model is an important prerequisite for revealing the rainfall-induced slope failure mechanism and disaster prevention and control. The traditional Green-Ampt model does not consider the distribution of soil

ERROR ANALYSIS ON THE ESTIMATION OF CUMULATIVE INFILTRATION SOIL USING GREEN AND AMPT MODEL

, 2014
Green and Ampt infiltration model is still useful for the infiltration process because of a clear physical basis of the model and of the existence of the model parameter values for a wide range of soil.
