Different numerical and analytical models are presently available that provide the tools to predict pollutant and water transfer processes between the soil surface and the groundwater level. Among the existing models, the Hydrus-1D model has been used for years in the prediction of water and pollutants transfer in the unsaturated zone. The main purpose of this paper was to model the movement of...

<p>El desarrollo del bulbo mojado bajo riego localizado en suelos enarenados presenta un comportamiento diferente observado homogéneos. La presencia de cultivo muy activo, también impone una serie variaciones que no han sido plenamente caracterizadas. El objetivo este trabajo es presentar la metodología adquisición datos y las precauciones necesarias para obtener modelo defina con precisi...

A field experiment was carried out during the spring season 2020 at University of Baghdad to study effect length and depth drip tape on wetting advance ofsubsurface irrigation system using Hydrus 2D/3D program. The site planted with sunflower in a clay loam texture. installed 0.3m below soil surfacein two lengths; 20m 40m. designed according arrangement split plotsdesign three replications. tre...
