ABSTRACT A simulation model was developed for field water table control when subsurface drainage flow is regulated with an automatic two-stage weir at the drainage outlet. Simulation results were compared with predicted water table drawdown for conventional drainage (no outlet control) and drainage controlled with a *Tixed elevation weir.
