Subsidence in Coastal Louisiana: Understanding Subsidence: Implications for Coastal Restoration and Protection Planning; New Orleans, Louisiana, 13 January 2009



The high rates of subsidence in coastal Louisiana are a well-documented component of regional land loss, ecosystem function deterioration, and coastal engineering failures. For agencies tasked with managing the effects of subsidence, the wide variability of these rates and their sharp spatial gradients pose significant challenges. Further, there is a lack of scientific consensus on what processes are most responsible for the observed subsidence, which creates uncertainty surrounding spatial patterns of subsidence, as well as a lack of consensus on what areas are most susceptible to it–not trivial questions for the resource management community.
