Extended Data Figure 7: Relationships between peak annual discharge and normalized EM score for historical floods in sedimentary archives.
From: Climatic control of Mississippi River flood hazard amplified by river engineering
Scatterplots and linear regressions with 1σ prediction intervals relating normalized EM score (a measure of grain size) to peak annual discharge of historical flood events for (a) MRY, (b) FLR and (c) STJ. Peak annual discharge estimates are from the Mississippi River gauging station at Vicksburg. Calibration periods vary owing to site-specific factors discussed in the Methods and Supplementary Information. adj., adjusted.
