Evapotranspiration from drained wetlands with different hydrologic regimes: Drivers, modeling, and storage functions

•Drainage reduces evapotranspiration (ET) from wetlands in the sub-tropics.•ET from a heavily-drained wetland was 34% less than a more functional wetland.•Main environmental drivers affecting wetland ET were inundation and net radiation.•Generic models (R2=0.76–0.84) can predict ET under variable hydrologic regimes.•Integrated with watershed models, wetland restoration effects on ET can be predicted.
