Fig. 4: Gauge-assimilated flows significantly improve the capture of trend relative to the natural flow in just a few plants.
From: Hydropower capacity factors trending down in the United States
Highlighted river basins (blue shading) contain one or more such plants (pink points). Spark lines for eight such cases show the observed trend in annual CF (black, bold type) and modeled trend using natural streamflow (orange) and gauge-assimilated (blue) streamflow (the slope of the trend line lies to the right of each sparkline, highlighting significant improvement in annual CF trend capture with the gauge-assimilated flow).
