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 ...

Rainfall infiltration analysis and infiltration model of slope based on in-situ tests

Rock and Soil Mechanics, 2021
Typhoon rainstorms occur frequently in the southeastern coastal areas of China. The infiltration of rainwater under typhoon rainstorm conditions is an important cause of landslides in hilly mountains.

A Novel Analytical Solution for Ponded Infiltration With Consideration of a Developing Saturated Zone

Water Resources Research, 2023
Ponding at the soil surface exerts profound impacts on infiltration. However, the effects of ponding depth on infiltration, especially the development of a saturated zone below the soil surface, have yet to be considered in present infiltration models. A

Analysis of Influencing Parameters of the Improved Model for Rainfall Infiltration in Unsaturated Tailings Soil

Advances in Civil Engineering, 2022
The rainfall infiltration analysis method is an important method for slope stability forecast and prevention. Slope angle and unsaturated soil layers are not shown in the conventional Green-Ampt (GA) infiltration model.

An integrated hydrological model based on improved Green-Ampt model and HYDRUS model for semi-humid and semi-arid plain areas

, 2020
Hydrology models of humid areas have always been studied deeply with higher model accuracy, but relatively less so for semi-humid and semi-arid areas, especially in plain. Here an integrated hydrology model (GA-HYDRUS model) was developed based on improved Green-Ampt model and HYDRUS model using the dataset of 7 rainfall events in Tianjin, China.

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

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
