Abstract EN
Crop water requirement is essential for agricultural water management, which is usually available for crop growing stages.
However, crop water requirement values of monthly or weekly scales are more useful for water management.
A method was proposed to downscale crop coefficient and water requirement from growing stage to substage scales, which is based on the interpolation of accumulated crop and reference evapotranspiration calculated from their values in growing stages.
The proposed method was compared with two straightforward methods, that is, direct interpolation of crop evapotranspiration and crop coefficient by assuming that stage average values occurred in the middle of the stage.
These methods were tested with a simulated daily crop evapotranspiration series.
Results indicate that the proposed method is more reliable, showing that the downscaled crop evapotranspiration series is very close to the simulated ones.
