Özet

The SLURP model was tested for the transferability of calibrated model parameters for different time periods in the Aksu Basin in the Black Sea region in Turkey. Two different scenarios were tested. The first scenario used three data sets: 1980-1982 data for calibration, 1983-1984 data for validation, and 1995-2000 data for evaluation. The second scenario used two data sets: 1995-2000 data for calibration and 1980-1984 data for evaluating transferability. Because a decrease in model performance occurred whenever using the calibrated parameters before and after calibration periods, the authors recommend updating calibrated model parameters whenever marked changes occur in the watershed.
