Decreased distance from the marsh to the marsh edge can lower groundwater tables and increase soil stresses that lead to subsidence. We explore the possibility that the canals that have been dug in the wetlands in coastal Louisiana have decreased marsh edge distances and therefore have contributed to subsidence.
