Influence of Soil Layers on the Infiltration Rates and Cumulative Infiltration Using Modified Green Ampt Model in the HYDROL-INF Simulation Environment [PDF]
International Journal of Agriculture System, 2022 Soil profiles are generally heterogeneous and consist of various horizontal layers due to geological processes, the formation of crusts, or other artificial or man-made activities.

The effect of sorptivity on cumulative infiltration [PDF]
Water Supply, 2020 Abstract Hydraulic parameters of the soil play a considerable role in the hydrological cycle, irrigation planning, drainage, groundwater recharge, and water resources management. One of the most important hydraulic parameters of the soil is sorptivity (S), yet there is insufficient research on how it affects the mechanism of infiltration.

New Analytical Model for Cumulative Infiltration into Dual-Permeability Soils [PDF]
Vadose Zone Journal, 2014 In the vadose zone, preferential flow and transport are much more common than uniform water flow and solute transport. In recent decades, several models have been developed for preferential water flow and physical non equilibrium solute transport. Among these models, the dual-permeability approach is an interesting tool for the conceptualization and ...

Modeling cumulative infiltration into dual-permeability soils
, 2023 Preferential flow is the rule rather than the exception, which questions the applicability of homogeneous models to simulate flows accurately. Gerke and van Genuchten (1993) developed the dual-permeability (DP) approach to account for preferential flow. This approach describes the soil as a combination of the fast-flow and the matrix regions.

Soil Research, 2017 Soil erosion is one of the most critical environmental problems currently facing Iran, and soil conservation is crucial for managing natural resources. The objective of this study was to investigate the effect of a vetiver cultivation system, known to be a valuable bioengineering technique, and polyacrylamide (PAM) addition on runoff, sediment load (SL)

Effect of Water Head and Irrigation Interval on Cumulative and Lateral Infiltration in Furrow Irrigation [PDF]
علوم و مهندسی آبیاری, 2019 Infiltration is considered as one of the most important soil parameters in the design and evaluation of furrow irrigation systems. Water is infiltrated through the wetted perimeter when it reaches a given point in the furrow until it recedes.

Estimation of Kostiakov İnfiltration Parameters Using Initial Soil Moisture
Journal of Agricultural Sciences, 2006 The Kostiakov equation was extensively used to estimate furrovv Infiltration but it is unadjusted for different field conditions. The Kostiakov infiltration parameters (k and a) were therefore developed as a function of initial soil moisture content and ...
