Journal of Engineering and Applied Science, 2023 In order to achieve proper water consumption efficiency in micro-irrigation systems, the space and flow rate of the drippers should match the hydraulic characteristics of the soil and the time and amount of plant irrigation water.

Advance of Wetting Front in Silt Loam Soil
Tikrit Journal of Engineering Sciences, 2013 Under drip irrigation , the plant's root is concentrated inside the wetted bulb (region). Thus, the development of these roots and the plant production are greatly affected by the wetting pattern.

Wetting front dynamics in an isotropic porous medium [PDF]
Journal of Fluid Mechanics, 2012 AbstractA new approach to the modelling of wetting fronts in porous media on the Darcy scale is developed, based on considering the types (modes) of motion the menisci go through on the pore scale. This approach is illustrated using a simple model case of imbibition of a viscous incompressible liquid into an isotropic porous matrix with two modes of ...

Roughness of moving elastic lines: Crack and wetting fronts [PDF]
Physical Review E, 2007 We investigate propagating fronts in disordered media that belong to the universality class of wetting contact lines and planar tensile crack fronts. We derive from first principles their nonlinear equations of motion, using the generalized Griffith criterion for crack fronts and three standard mobility laws for contact lines.

Wetting Fronts in One-Dimensional Periodically Layered Soils [PDF]
SIAM Journal on Applied Mathematics, 1998 The paper deals with the existence, uniqueness and large time asymptotic stability of traveling wave solutions to the Richards equation. This model describes the vertical infiltration of water through one-dimensional periodically layered unsaturated soils.

Investigation of the Wetting Front Distribution in Vertically Layered Arid Soils under Drip Irrigation [PDF]
Journal of Hydraulic and Water EngineeringSoil wetting front depends on various factors, including soil texture, emitter flow rate, land slope, and volume of irrigation water. Accurate estimation of the curved shape of the wetting front distribution helps to know how much advanced water and ...

Density-wave fronts on the brink of wet granular condensation [PDF]
Scientific Reports, 2017 AbstractDensity-wave fronts in a vibrofluidized wet granular layer undergoing a gas-liquid-like transition are investigated experimentally. The threshold of the instability is governed by the amplitude of the vertical vibrations. Fronts, which are curved into a spiral shape, propagate coherently along the circular rim of the container with leading ...
