Simulation of real-time variations of saline drainage water: comparing system dynamics with DRAINMOD-S

Accurate simulations of wastewater quality and quantity, particularly in saline and semi-arid areas, are important in agricultural water management. In this study, a system dynamics (SD) approach was proposed to simulate drainage water and groundwater salinities, water table fluctuation, and drainag...
