LCI awarded a research grant to Ian McGregor, Chris Bloszies, and Jeff Unruh to evaluate land subsidence in southern Louisiana using stream gauge data. This study will constitute a “proof-of-concept” test to derive a suite of time series of land subsidence from the stream gauge data, which can then be used to evaluate time- and space-varying patterns of land subsidence in the Mississippi Delta region of southern Louisiana. The stream gauge data will supplement existing land survey and GPS data to provide a longer-term and more spatially extensive evaluation of subsidence rates for risk evaluation studies and for use in future engineering design and mitigation.
