Streamflow records play important role for design, planning and management of water structures
in any region. In order to use the streamflow efficiently for these purposes, the length of data records must be
statistically sufficient and complete. But, there are usually some gaps at the streamflow records and these gaps must
be infilled by means of reliable methods. In this study, the missing streamflow records in the gauge stations 2119,
2151, 2149, 2158 and 2122, which are located in the upper and middle parts of the Euphrates Basin, were estimated
using Flow Duration Curves and Regression Models. To define the best model among alternatives, determination
coefficient (R2) and Root Mean Square Error (RMSE) were used. According to the results, both of the models
produced successful results with a high value of R2. Moreover, the results showed that the Regression Models
for the stations 2151, 2119, 2122 and 2158 and Flow Duration Curves for the station 2149 were more capable to
preserve the main statistical properties of the historical data.
