Tracking the Sediment Carried by the Muddy Mississippi

by Delaney Dryfoos 10 June 20259 June 2025

New research shows that typically, less than 10% of land-building alluvium reaches the Bird’s Foot Delta region, the southernmost reach of the river, where it meets the Gulf.

A view of a bridge, with the New Orleans skyline visible in the distance between the bridge and the water. A purple tint, a teal curved line representing a river, and the text “#AGU25 coverage from Eos” overlie the photo.
