Simulated water table management by controlled drainage based on rainfall forecasts



Simulated water table management by controlled drainage based on rainfall forecasts



Transactions of the ASAE, American Society of Agricultural Engineers 29(4): 988-994



A simulation study using DRAINMOD was conducted for southern USA humid climate and soil conditions to evaluate growing season water table management by controlled-drainage. Control was simulated by regulating the depth of an overflow weir at the drainage outlet. A rainfall probability INDEX, computed from daily records of National Weather Service forecasts, was used to simulate an override of the weir depth control, permitting free drainage in advance of predicted rainfall events.
