Algorithm Detects Thousands of Missing Levees from U.S. Database
An existing levee database accounts for just one fifth of the country’s actual total levee count, limiting the study of how these embankments affect riparian ecosystem health in the United States.
How River Engineering Alters Carbon Cycling
Artificial levees in the Lower Mississippi River bypass floodplain processing and increase delivery of carbon to the ocean.
High Water: Prolonged Flooding on the Deltaic Mississippi River
Changing climate and land use practices are bringing extended periods of high water to the lower Mississippi River. New management practices are needed to protect people, industry, and the land.
It’s Time to Revise Estimates of River Flood Hazards
Accurately assessing flood hazards requires a better understanding of the feedbacks between natural and human influences on the characteristics of rivers.
Diverting the Mississippi River May Not Save Louisiana’s Coast
New research finds that man-made river diversions have previously led to land losses.
Gulf Dead Zone Looms Large in 2019
A new forecast predicts widespread hypoxia after a wet Midwest spring.
Secrets from the New Madrid Seismic Zone’s Quaking Past
High-resolution lidar topography reveals a long history of ancient earthquakes.
Rethinking the River
The Mississippi River and its delta and plume provide insights into research-informed approaches to managing river-dominated coastal zones.
Reimagining a Fatal Flood
Researchers use high-resolution simulations to reexamine the rainfall events that led to one of the most destructive floods in U.S. history.
