Field evaluation of evapotranspiration models under Canadian Prairie conditions

Authors: Ndulue, Emeka; Sri Ranjan, Ramanathan
Description: An accurate estimate of evapotranspiration (ET) is important for determining the water demand of field crops, irrigation scheduling, field water management, and hydrological modeling. The ET can be directly determined by measuring the water uptake of the plant either using a lysimeter or by transpiration flow measurement methods. Since direct measurements are costly weather data has been used as input in various ET models to predict potential ET. This study aims at directly measuring crop ET and comparing it with those predicted by different ET models using meteorological data obtained from a field site in Manitoba.
