## Abstract

Mud from the Mississippi River built the vast wetlands of Louisiana. Nearly 2000 sq. miles of these wetlands have become open water since the 1930s, wiping out coastal communities and leaving others vulnerable to natural hazards. Crevasses – cuts in the river levee where water and mud flow into the surrounding wetlands are a proven, economical tool for rebuilding these wetlands. River managers have historically adopted a policy of closing crevasses because these cuts can impact the use of the river as a navigation channel and enhance salinity intrusion when the river is low, threatening drinking water supplies. However, crevasses are expected to become more common in the coming decades, especially in areas where channel bank protection is less intensive. The United States is currently lacking a formal framework to incorporate crevassing as part of river management efforts. This project brings together state and federal resource management agencies, private organizations, environmental advocacy nonprofits, and local universities and technical colleges. The project will create the tools and techniques needed to support effective management decisions and to develop a workforce that is both connected to community needs and capable of contributing to long-term planning and adaptive management of the crevasse system.

On the lower Mississippi River, crevasse management is key to sustaining valuable wetlands while enabling the river to meet the needs of communities and commerce. C
