Innovative irrigation solutions have to face water scarcity problems affecting the Mediterranean countries. Generally, surface (DI) or subsurface drip irrigation systems (SDI) have the ability to increase water productivity (WP). But the question about their possible utilization for crops such as corn would merit to be analysed using an appropriate economic tool. The latter would be necessary b...

in this study, effect of slope on soil wetting pattern under surface drip irrigation and simulation with hydrus-2d model evaluated.the physical model made of plexiglas to size 83, 6 and 54 cm (length, width, height) filled with silty clay loam soil was used. to achieve the desired discharge, a small drip irrigation system created that includes a water tank with a fixed height (about 2 meters), ...

The HYDRUS-1D and HYDRUS (2D/3D) computer software packages are widely used finite element models for simulating the one-, and twoor three-dimensional movement of water, heat, and multiple solutes in variably-saturated media, respectively. While the standard HYDRUS models consider only the fate and transport of individual solutes or solutes subject to first-order degradation reactions, several ...

Sub-surface irrigation with porous clay pipe can be an efficient, water saving method of irrigation for many less developed arid and semi-arid regions. Maximizing the efficiency of clay pipe irrigation requires guidelines and criteria for system design and operation. In this study, experimental and simulated (with HYDRUS (2D/3D)) soil wetting patterns were investigated for sub-surface pipe syst...

Abstract One of the problems involving water bodies is pollution sources, which later becomes parent various social, economic, and health problems. these conditions can be overcome by utilizing phytoremediation through constructed wetlands. HYDRUS a software that offers easy modelling pollutant decay mechanisms in wetlands using finite element method. This study aims to show analyse how model m...
