Table 5: Percentage change in streamflow and sediment yield compared to historical data. INMCM4 and MPI-ESM1-2 HR models showed peak streamflow in July, while the ACCESS-CM2 model indicated a peak in August. The Ecearth3 model showed a peak in September for streamflow, while the CanESM5 model exhibited a peak in October. Figure 6 also showed the future streamflow predictions followed the similar historical patterns of streamflow peaks in both watersheds under all scenarios.
