Water Budget of Maize on Heavy Clay in a Continental Climate: Field Experimentand Model Simulation. Final Report of the Project 'Evaporation Estimation Comparison.'

摘要

The report documents the field activities, the resulting data set, and modelvalidation results. In chapter 2, the setup of the field experiment and primary data analysis as performed during the experiment is described. The theory and data analysis concerning calculation of actual evapotranspiration, potential evapotranspiration, and characterization of soil hydraulic properties is given in chapter 3. Also included is a comparison of the water budget terms evapotranspiration and soil moisture depletion. In chapter 4, the structure of the models DAIR and SWAP93 is described. Validation results are presented in chapter 5. Conclusions and recommendations are finally given in chapter 6.
