Numerical Simulation of Soil Water Movement under Subsurface Irrigation

Irrigation Management of Subsurface Drip Irrigation of Palm Trees under Arid and Semiarid Regions

In order to investigate the effect of water quantity in subsurface drip irrigation on water use efficiency of palm yield and yield components, and determining suitable irrigation treatments for three different date cultivars, a split plot experiment design in a randomized complete block design with three replications were applied for three cropping years (2013-2016), at Behbahan Agricultural Re...

The Role of Hydraulic Conductivity in Modeling the Movement of Water and Solutes in Soil Under Drip Irrigation

simulation of salinity distribution in soil under drip irrigation tape with saline water using swap model

introduction: the to be limited available water amount from one side and to be increased needs of world population from the other side have caused increase of cultivation for products. for this reason, employing new irrigation ways and using new water resources like using the uncommon water (salty water, water drainage) are two main strategies for regulating water shortage conditions. on the ot...

Numerical analysis of a pollutant dispersion in subsurface soil

A hydraulic scale model was used in a laboratory experiment for the purpose of understanding the characteristics of a pollutant dispersion in subsurface soil. The experimental site was an area near a radioactive waste repository in the Republic of Korea. The hydraulic scale model was designed and manufactured in geometric similarity to the actual site. The tracer 99mTc which has a short half-li...

The effect of irrigation water quality on soil properties under center pivot irrigation systems in central Saudi Arabia

A field experiments were conducted for three growing seasons (2007 to 2009) at five different sites of soil types and salinity levels. Five different ground water qualities were used to irrigate five fields each with area of 50 to 54 hectares planted with wheat crop and the irrigation system used at each field was center pivot sprinkler system. The irrigated fields were located at different loc...
