The checking needs to be completed by Reclamation, <br />. the Service, and members of the study team if possible. <br /> <br />Calibration - is when the model is 'fitted' or 'fine-tuned' to <br />the characteristics of the real world system being studied. A <br />model is considered to be calibrated when model results match <br />observations taken from the system under investigation. <br /> <br />Calibration - period was set for 1961 to 1975. <br /> <br />Parameters to be check during calibration and the order of <br />importance. <br />a.
