Modified Green-Ampt model for infiltration analysis in loess area and its parameter determination and verification

open access: yesScientific Reports
Water infiltration into soil is important in geotechnical engineering. The classical Green-Ampt (GA) infiltration model is widely used in soil infiltration due to its physical significance, but it ignores the actual unsaturated layer in the infiltration ...

The Effects of Concentration of Ponding-Infiltration Water on Water and Salt Movement in Soils

open access: yesGuan'gai paishui xuebao, 2021
【Background】 Seasonal water shortage in southern China has made water supply unable to meet the demand and using unconventional water as a supplementary resource for irrigation can partly relieve this pressure.

Calculation of safety factor of slope stability considering the effect of closed air

open access: yesShuili Shuiyun Gongcheng Xuebao, 2022
Intense rainfall always results in the air in soil slopes being closed, and it will decrease the slope stability therefore. The present research mainly focuses on the effect of closed air pressure on infiltration and on the stability safety factor of an ...

Improved Green-Ampt infiltration model of soil slope considering inclination

open access: yesShuili 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 ...
