Research on Rainfall Infiltration Characteristics of Loess Slopes Based on Different Rainfall Intensities

Renmin Zhujiang, 2023
In this paper,a homogeneous loess slope in Qingyang,Gansu Province is used as a reference prototype.An indoor model slope that satisfies similar conditions is built.Rainfall infiltration experiments are carried out on the slope under different rainfall ...

Estimation of Effective Rainfall Guidance Considering Infiltration Capacity-Rainfall Intensity [PDF]

Journal of Korean Society of Hazard Mitigation, 2013
This study investigated the effect of the lag time on the concentration time and the change in effective rainfall depending on the infiltration capacity and rainfall intensity by the status of land use to research the relevance of infiltration capacity-rainfall intensity and the effective rainfall by land categories according to the characteristics of ...

Transforming Agricultural Water Management Through the Water–Energy–Food Nexus: Trends, Opportunities, Barriers and Solutions

Irrigation and Drainage, EarlyView.
ABSTRACT Agricultural water management (AWM) is increasingly transitioning towards transformative thinking, where interconnected sectors, including water, energy and food, are managed holistically. Trends point towards cross‐sectoral and harmonised strategies to optimise water use efficiency and productivity, integrate renewable energy, promote ...

Coupling Analysis of Rainfall Infiltration and Slope Runoff in Two-layered Slope

工程科学与技术, 2020
Natural soil slopes often consist in two or more soil layers due to the geological and human factors. Under heavy rainfall, rainwater infiltrates into the slope, and when the rainfall intensity is greater than the infiltration rate of the soil, the ...

Impact of Irrigation Scheduling on Corn Yield and Water Balance in Sandy Soils of Central Minnesota Using the EPIC Model.

Irrigation and Drainage, EarlyView.
ABSTRACT Efficient irrigation scheduling is critical in sandy soils to achieve optimum yield and maximum net benefit with minimum environmental concerns. The Environmental Policy Integrated Climate (EPIC) model was used to study the impacts of autoirrigation of corn on crop yield and soil water balance during 2019–2021 at −300 and −450 kPa for loamy ...

Numerical Analysis of Rainfall Infiltration in the Slope with a Fracture

, 2005
With the finite volume method, a 2D numerical model for seepage in unsaturated soil has been established to study the rainfall infiltration in the fractured slope.The result shows that more rain may infiltrate into the slope due to existing fracture and ...
