I would recommend choosing a calibration and a validation period, and you can split it down the middle since you have so many years of data. Therefore, I would calibrate the model using the data from 1987-2000. Try to get the model’s results to match the observed data as closely as possible, using values for Nash Sutcliffe and other statistical indicators. These should be reported in your final write-up about the model. Then, for the years 2000-2013, use the same parameters you used for 1987-2000 (don’t change anything) and report the values for the same statistical indicators. The validation period is a test of how well your calibration applies to an time period not included in your calibrated data.
