Abstract

The bucket with a bottom hole (BBH) model of soil hydrology was improved to incorporate bioprocesses such as interception and macropore flow into it by adding three model parameters, which is called the BBH-B model. This model was applied to the estimation of evapotranspiration (ET) from a cornfield in the upper Yellow River basin, China, with the results as follows: Estimates of the cumulative ET for periods of about one month were made using the BBH-B model with fair accuracy, if the three additional parameters were determined appropriately. It was also found that ET had a large spatial variation within the cornfield.
