Self-adaptive Green-Ampt infiltration parameters obtained from measured moisture processes
Water Science and Engineering, 2016 The Green-Ampt (G-A) infiltration model (i.e., the G-A model) is often used to characterize the infiltration process in hydrology. The parameters of the G-A model are critical in applications for the prediction of infiltration and associated rainfall ...

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 ...

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 ...

The Development of A mathematical Model to Predict Runoff From A micro-catchment under High Water Application Rates [PDF]
, 1988 Current trends in sprinkler irrigation to improve application uniformity and reduce energy requirements haste led to problems of water application and potential surface runoff, which in turn have highlighted the importance of the soil and cultivation

Instrumented soil column model for rainfall infiltration study
, 2008 Infiltration and changes on pore-water pressure in soil must be taken into account in most slope stability and seepage problems. Laboratory experiments were performed to examine one-dimensional rainfall infiltration behavior of unsaturated soil.

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 ...

Irrigation and Drainage, EarlyView.ABSTRACT Global warming has intensified prolonged droughts in many regions, including Türkiye, resulting in growing pressure on already limited water resources. Agriculture, as the largest water‐consuming sector, faces critical challenges in sustaining productivity under increasing water scarcity. In this context, assessing water use efficiency through

Irrigation and Drainage, EarlyView.ABSTRACT Crop modelling is essential for agricultural water management but often relies on simplified water balance routines that limit representation of soil moisture dynamics. To address this limitation, we developed a coupled model that integrates the 1‐D Richards equation, solved using a finite difference method into the FAO AquaCrop.
