Introduction
Compounding the subsidence problem is the forecast that the world's oceans will rise over the next century due to global atmospheric warming. Together the rising sea and subsidence accelerate coastal erosion and wetland loss, increase flooding, and increase the extent and frequency of severe storm impacts. To assess the impact of marine trangression caused by subsidence and sea-level rise at a given location, it is necessary to have a thorough understanding of the natural processes that operate on the delta plain. Reliable scientific data are needed to identify the 'hot spots' of subsidence, where infrastructure is most at risk, and what are the best strategies to sustain and restore Louisiana's coastal wetlands. In this collaborative study, the US Geological Survey (USGS), US Army Corps of Engineers (USACE), and University of New Orleans (UNO) are responsible for developing an objective and reliable scientific database on subsidence and sea-level rise for managers, planners, and researchers by conducting detailed studies within the Mississippi River delta plain.
