To the Editor —

More than 13,000 km2 of the Mississippi River delta region are in danger of submergence by the year 21001,2, and engineered diversions of Mississippi River water and sediment are critical to delta sustainability3,4. Nittrouer and Viparelli5 examine Mississippi River sand supply within this context. Here we comment on several points that merit further scrutiny.
