is there the possibility to use actual evapotranspiration (measured in our case) as a boundary condition? Maybe by not simulating root water uptake and modifying some input file ?
Thank you for your help,

You can you actual values of evaporation and transpiration and adjust the parameters affecting the reduction from potential to actual values (e.g., Feddes parameters) such so that there is no much further reduction. However, there will likely still be some reduction. J.
