Fig. 4: Spatial distribution of aging dams and recent trends in extreme joint precipitation events across the CONUS.
From: Increasing dam failure risk in the USA due to compound rainfall clusters as climate changes
Spatial distribution of aging dams and recent linear trends in (a) joint event of 100-year annual maximum daily and 10-year previous 5-day rainfall, and (b) joint event of 100-year annual maximum daily and 10-year previous 30-day rainfall, for the 1979-2021 CPC-CONUS daily rainfall dataset. The color represents the ratio of the return level in 2021 to that in 1979. Only large-sized dams, with height > 12.2 m (40 ft) or storage capacity > 1.23 million m3 (1000 acre-ft), categorized as high or significant hazard dams are displayed.
