| Abstract: |
| To evaluate the Hamon potential evaporation (PE) model in the Yellow River Basin, daily mean air temperature and sunshine hours climate data from 1965 to 2014 at 64 meteorological stations of the Yellow River basin are collected, monthly PE calculated by Hamon model are compared with that calculated by Penman-Monteith model as reference value, the results show that without changing the parameter of Hamon model, Hamon model’s performance is not well, the calculated PEs are relatively smaller that reference values. After Hamon model calibration with measured data, good calculation accuracy of PE is obtained. Furthermore, when using mean annual average sunshine duration together with daily air temperature to calibrate Hamon model, the results showed that the model's efficiency coefficient was further improved, indicating that Hamon model had better application effect and prospect in arid and semi-arid regions. |
