Layered Green and Ampt Infiltration With Redistribution

Peter La Follette et al.

Summary: This paper describes an extension of the Green and Ampt method into layered soils on a continuous basis, which is called Layered Green and Ampt with Redistribution (LGAR). Results show that LGAR is a mass-conservative, computationally efficient, reliable and reasonably accurate method for simulating infiltration over extended time periods compared to the numerical solution of the Richards equation (RE) in layered soils in arid and semi-arid regions.

Approximate analytical solutions for one-dimensional soil water movement equation with arbitrary initial conditions

Lijun Su et al.

Summary: Simple analytical solutions for one-dimensional horizontal and vertical soil water movement are crucial for estimating soil hydraulic parameters and achieving precision irrigation. This study presents approximate analytical solutions based on the principle of least action and variational principle, for the problem of horizontal absorption and vertical infiltration in soil under arbitrary initial conditions and constant boundary conditions. Algebraic functions for soil water content, cumulative infiltration, infiltration rate, and infiltration time are obtained. Results show that these analytical solutions have high precision in predicting soil water infiltration, as compared to numerical simulations. The relationships between cumulative infiltration and wetting front distance/depth, infiltration rate and reciprocal of wetting front distance/depth, and square of wetting front distance/depth and infiltration time are found to be nonlinear for arbitrary initial conditions. The initial conditions have little effect on the relationship between infiltration rate and wetting front distance/depth when the initial soil water content is lower than 0.6 theta(s). Additionally, stable infiltration wetting front distance/depth and time are determined based on the nonlinear relationships between infiltration rate and wetting front distance/depth in vertical infiltration.

A computationally efficient hydrologic modeling framework to simulate surface-subsurface hydrological processes at the hillslope scale

Lin Chen et al.

Summary: Considering the interaction between surface and subsurface is crucial for predicting water movement and quality in the environment. In this study, a new efficient coupling routine for 1D surface-subsurface modeling was developed by combining KINEROS2 (K2) and HYDRUS-1D (H1D) open-source codes. The approach successfully accounted for surface ponding and water exchange between the two model domains, allowing for accurate representation of subsurface behavior below each overland flow plane.

The effect of hillslope geometry on Hortonian rainfall-infiltration-runoff processes

Jie Wang et al.

Summary: This study investigates the impact of hillslope geometry on Hortonian rainfall-runoff processes. Different geometrical characteristics can lead to variations in runoff and infiltration processes. Current rainfall infiltration prediction methods may have errors when applied to hillslopes with curved profiles and variable widths.

Modeling slope rainfall-infiltration-runoff process with shallow water table during complex rainfall patterns

Songbai Wu et al.

Summary: The study modified Smith et al. (1993)'s infiltration model and developed a modeling framework for simulating the rainfall-infiltration-runoff process in presence of a water table. The model showed good agreement with experimental data and performed well under complex rainfall patterns. Comparisons with other models indicate that the modified model offers realistic and accurate predictions for infiltration and runoff in the presence of a water table.

Calibration of Green-Ampt wetting front suction for ponding and non-ponding infiltration scenarios

Caroline Andrade Pereira et al.

Summary: Calibrating the effective matric suction at the wetting front can improve the performance of the Green-Ampt model, especially for different soil types, water supply regimes, and initial matric suction. Reduction of wetting front matric suction may be necessary to approach numerical simulations, even during rainfall events.
