The coastal landscapes surrounding New Orleans are rapidly subsiding and eroding into the Gulf of Mexico. These wetlands have historically provided a buffer for hurricane storm surges, thus complementing traditional flood protection strategies like levees and pumps. As the land loss crisis has accelerated over the last fifty years, state officials have experimented with a wide range of water management strategies designed to prevent saltwater intrusion, build new land, and promote plant recruitment. These strategies, outlined in the state’s Coastal Master Plan, include the placement of dredged sediments in eroded landscapes, the diversion of the Mississippi River into its historical floodplain, and the use of treated effluent to freshen estuaries. This field trip will visit three sites on the eastern periphery of New Orleans that provide context for the region’s relationship to water and deltaic ecosystems, and demonstrate experimental sites that span the types of interventions currently under development. These projects will be vital to the transformation of the Lower Mississippi River Delta over the next several decades. Participants will gain a detailed understanding of the range of climate-driven threats to New Orleans and coastal Louisiana, and see concrete examples of the suite of infrastructural tools local officials are deploying to adapt the delta’s ecological functions and geophysical extent.
