A Dynamic Multidomain Green‐Ampt Infiltration Model [PDF]

open access: yesWater Resources Research, 2018
AbstractShrink‐swell soils possess dynamic hydraulic properties, which may limit the applicability of traditional models for simulating infiltration and overland flow. This study incorporates Green‐Ampt infiltration concepts into a multidomain porosity framework to account for variations in pore size distributions and saturated hydraulic conductivities

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]

open access: yes, 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

open access: yesGeoderma
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.

KAJIAN LAJU INFILTRASI PADA LERENG YANG TERTUTUP ABU VULKANIK BERDASARKAN EKSPERIMEN SKALA LABORATORIUM

open access: yesJurnal Sumber Daya Air, 2022
Indonesia has 129 active volcanoes; therefore, the volcanic-related disasters risk is relatively high. Lahar flood is a secondary post-eruption disaster, which is triggered by the rainfall due to the movement of volcanic material by the runoff. After the

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

open access: yesYantu 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

open access: yesYantu 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

Theoretical Investigations to Aid in the Prediction of Combined Sewer Overflows in Coastal Urban Watersheds: Case Study of San Francisco

open access: yesWater Resources Research, Volume 62, Issue 11, November 2026.
Abstract Combined sewer systems (CSS) function in about 700 U.S. municipalities, with over 100 near vulnerable coastal waters. Predicting changes due to rainfall, sea level rise (SLR), and groundwater rise is vital for adaptation. This study compares a hydrologic‐hydraulic model (PCSWMM) and a hybrid mass balance method for estimating combined sewer ...
