WASHINGTON – Current design standards for United States hydrologic infrastructure are unprepared for the increasing frequency and severity of extreme rainstorms, meaning structures like retention ponds and dams will face more frequent and severe flooding, according to a new study.

Extreme weather events are on the rise, but U.S. water management systems use outdated design guidelines. New research, published in the AGU journal Geophysical Research Letters, analyzed data from multiple regions throughout the U.S. and found the rising number of extreme storms combined with outdated building criteria could overwhelm hydrologic structures like stormwater systems.

The new study is particularly timely in light of recent storms and flash floods along the East Coast... FULL ARTICLE
