Title

CALIBRATION METHODS TO ESTIMATE REFERENCE CROP EVAPOTRANSPIRATION AND CALCULATED POTENTIAL WATER REQUIREMENTS OF OLIVE PLANT IN KERMANSHAH PROVINCE

Pages

  45-64

Abstract

 Estimating the WATER REQUIREMENT is among the most important factors in the design of irrigation and water resources management. To determine the WATER REQUIREMENT, the evaporation-transpiration point of the reference crop should be estimated. Given that a variety of methods have been recommended in this regards, selecting the appropriate method is a hard and complex task. In this study, five selected stations in KERMANSHAH PROVINCE during the period between 17 and 54 years were used. Five methods including FAO - Penman - Monteith, Thornthwaite, Modified Blaney-Criddle, modified Hargreaves and Penman have been used to do the needed calculations which are done based on monthly and annual data. The calculated values of the potential evaporation - transpiration and the recommendations of the World Meteorological Organization indicated that of the five methods mentioned above FAO - Penman - Monteith provides a more accurate estimate. The results showed that the monthly and annual maximum ET0 were 8.5 and 48.9 millimeters which was for Ravansar station and the minimum order of 5.8 and 38.4 mm which was experienced in Kangavar station, and finally it showed that the maximum annual WATER REQUIREMENT for Ravansar station is 923.3 mm.
