Application of the SWAP model to simulate water–salt transport under deficit irrigation with saline water

The agro-hydrological Soil–Water–Atmosphere–Plant (SWAP) model was calibrated and validated to simulate water–salt transport based on field experiments in an arid region of China. The simulation results show lower soil water content but higher salt concentration under deficit irrigation. Soil water and salinity below 95 cm at 80% evapotranspiration ( E T c ) treatments and 65 cm at 60% E T c treatments were hardly affected by irrigation. With...
