Effects of the Grain Size on Dynamic Capillary Pressure and the Modified Green–Ampt Model for Infiltration

open access: yesGeofluids, 2018
Darcy-scale capillary pressure is traditionally assumed to be constant. By contrast, a considerable gap exists between the measured and equilibrium capillary pressures when the same moisture saturation is considered with a high flow rate, and this gap is

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

Quantification of flash flood peaks using computer simulation for potential hill torrents of Pakistan: A modeling study

open access: yesRiver, Volume 5, Issue 3, Page 432-452, August 2026.
Abstract This study investigates rainfall runoff behavior of five major torrential Nullahs' of Dera Ghazi Khan (D. G. Khan) for flash flood events. The integration, and fusion of satellite‐based meteorological, topographical, and pedo‐transferred function's (PTF) derived soil hydraulic datasets at 250 m grid size substantially proves a viable approach ...

Neighbour Effects and Dynamics of Plant‐Associated Microbiomes in a Strip‐Crop System

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Distinct plant species differentially affect the assembly of host‐associated microbial communities in a strip‐crop system. Crop neighbouring effects on the microbiomes were highest at the edge of the strips, which further reveals reduced leaf pathogens.

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

open access: yesJournal 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

open access: yesRevista 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.

Wildfire Impacts on Hydrology: A Forested Catchment Case Study in Temperate Australia

open access: yesHydrological Processes, Volume 40, Issue 9, September 2026.
Immediately after a wildfire (Scenario 1), surface runoff increased by 34.65%. In Scenarios 2 and 3, it increased slightly (0.96%), while in Scenario 4, it rose 1.04% then decreased as vegetation resprouted. Evapotranspiration decreased by 10.27% immediately after the wildfire, then increased by 1.58%, 0.27%, and 0.84% for Scenarios 2, 3, and 4 ...

A Comparison of Green-Ampt and a Spatially Variable Infiltration Model for Natural Storm Events

open access: yes, 1999
Rainfall-runoff data collected from bare plots (20-216 m2) at 1-min intervals were used to compare the performance of the Green-Ampt infiltration model and a spatially variable infiltration model (SVIM). The two models have the same number of parameters.

Green-Ampt infiltration model parameter determination using SCS curve number (CN) and soil texture class, and application to the SCS runoff model [PDF]

open access: yes, 2001
The U.S. Department of Agriculture (USDA) Soil Conservation Service Curve Number (SCS CN) method is a simple and widely popular technique of estimation of direct runoff volume for design and natural rainfall events in small watersheds.

Rapid Hydraulic Modelling in Post‐Wildfire Channels Using a Tiered Framework

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
A three‐tier hydraulic modelling framework enables rapid, safe calibration of post‐wildfire channel models using remote sensing and limited field data. Tested on two contrasting burned Colorado watersheds, discharge and salt tracer velocity measurements alone captured most of the achievable model accuracy, with detailed bathymetric survey adding little
