Peak Flows and Summer Flow None on the models effectively represent peak flows (Figure 5). By way of example, inside the calibration period of your Q2 catchment (native forest cover), the models showed an underestimation ranging amongst 20 and 70 for GR4J, 18 and 70 for GR5J and in between 10 and 62 for GR6J, although within the validation period the models showed an underestimation ranging among 21 and 62 for GR4J and GR5J and between 15 and 58 for GR6J. In the calibration period of Q3, the models showed an underestimation ranging betwe.
