Measured and Predicted Evaporation at Pasaje, Ecuador

Resumen

To determine the water requirements of bananas and certain other crops in the coastal region of the Jubones River basin, southern Ecuador, a study was made of the measured and computed evaporation regimes based on the Class A pan. Piche evaporimeter and climatic data covering 84 months at one station in the project area. This note summarizes the results of the study and provides some evidence showing that certain empirical evapotranspiration formulas are less sensitive under climatic conditions other than those under which they were developed.
