A model of solute transport in overland flow is developed and applied to the simulation of surface fertigation. Water flow is simulated using the depth-averaged, one-dimensional shallow water equations. Solute flow is represented by an advectiondiffusion model. The resulting set of three partial differential equations is sequentially solved at each time step. First, water flow is computed using...

The Ord River Irrigation Area (ORIA) is located within northern Western Australia near the Northern Territory border. Since the beginning of irrigated agriculture in the ORIA the groundwater levels have been continuously rising and are now close to the soil surface in some parts of ORIA in northern Western Australia. The groundwater is now saline throughout most of the ORIA and soil salinity ri...

Water management and utilization is an ongoing problem in developing countries with semi-arid to arid climates such as Afghanistan. The lack of effective irrigation systems are oftentimes the most limiting factor for maximizing agricultural productivity in these countries. In Afghanistan, the most widely used irrigation methods are basin/border for cereal crops and furrow for vegetables and gra...

Marginal agricultural land provides opportunities to diversify landscapes by producing biomass for biofuel, and through floral provisioning that enhances arthropod-mediated ecosystem service delivery. We examined the effects of local spatial context (adjacent to woodland or agriculture) and irrigation (irrigation or no irrigation) on wildflower bloom and visitation by arthropods in a biofeedsto...

The shortage of water resources makes it urgent to increase agricultural irrigation efficiency. In response this need, study develops a real-time adaptive control (RACI) system for border irrigation. Avoiding the need traditional systems calculate soil infiltration properties in real-time, RACI adjusts inflow rate based on difference between actual and expected advance time. Simulations collect...
