Fig. 4: Sensitivity of processes over time at selected locations.
From: The sensitivity of simulated streamflow to individual hydrologic processes across North America
The importance of the eleven hydrologic processes (colorbars in right column panels) on each day of the year (average over 20 simulated years) are shown for eight example locations (a–h). These example locations are indicated by the USGS or WSC gauge station identifier added as a label at the top of the right column panels. These eight representative locations are the centers of eight clusters based on the three climate indicators. The clustering and example basins are derived to show the spatial variation of the process sensitivities over time in various climatic regions. Each cluster is named using the major physiographic or ecohydrologic region it covers (label on top of left column panels). For reference, the average weight of each day of the year based on the average simulated streamflow is displayed (black line in right column plots). These weights are used to derive time-aggregated sensitivities (see Fig. 3) from the time-dependent sensitivity indices displayed here in order to increase the weight of timesteps with high flows as compared to low-flow timesteps.
