[1] Geodetic leveling observations from Biloxi, MS, to New Orleans, LA, and water level gauge measurements in the New Orleans–Lake Pontchartrain area were analyzed to infer late 20th century vertical motions. These data were used to test the validity of previous subsidence rate measurements and the models that predict the location and causes of subsidence. Water gauges attached to bridge foundations and benchmarks affixed to deep rods that penetrate Holocene strata subsided as much as 0.8 m… 
Resolving the contributing factors to Mississippi Delta subsidence: Past and Present
To date, quantification of individual components that contribute to shallow and deep‐seated subsidence in passive margin deltas worldwide has proven problematic. A new, regional gridded
Anthropogenic and geologic influences on subsidence in the vicinity of New Orleans, Louisiana
New measurements of ongoing subsidence of land proximal to the city of New Orleans, Louisiana, and including areas around the communities of Norco and Lutcher upriver along the Mississippi are
A Synoptic Examination of Causes of Land Loss in Southern Louisiana as Related to the Exploitation of Subsurface Geologic Resources
ABSTRACT Olea, R.A. and Coleman, J.L., Jr., 2014. A synoptic examination of causes of land loss in southern Louisiana as related to the exploitation of subsurface geologic resources. During the last
Measuring, modelling and projecting coastal land subsidence
Coastal subsidence contributes to relative sea-level rise and exacerbates flooding hazards, with the at-risk population expected to triple by 2070. Natural processes of vertical land motion, such as
Recent subsidence rates for Barataria Basin, Louisiana
Subsidence in south Louisiana is a fundamental process and major source of uncertainty influencing restoration planning and design and wetland habitat resilience. The primary goal of this study was
Mechanisms of late Quaternary fault throw‐rate variability along the north central Gulf of Mexico coast: implications for coastal subsidence
Quaternary sea‐level cycles have caused dramatic depocentre shifts near the mouths of major rivers. The effects of these shifts on fault activity in passive margin settings is poorly known, as no
Coastal Land Loss and Landscape Level Plant Community Succession: An Expected Result of Natural Tectonic Subsidence, Fault Movement, and Sea Level Rise
Abstract This paper examines the natural and anthropogenic factors that are present and absent at Goose Point. Goose Point is of interest because it lacks most of the “usual (anthropogenic) suspects”
Novel Quantification of Shallow Sediment Compaction by GPS Interferometric Reflectometry and Implications for Flood Susceptibility
Estimates of flood susceptibility and land loss in the world's coastal regions depend on our knowledge of sea level rise (SLR) from increases in ocean mass and volume, as well as knowledge of
Is There Deep-Seated Subsidence in the Houston-Galveston Area?
Long-term continuous groundwater level and land subsidence monitoring in the Houston-Galveston area indicates that, during the past two decades (1993–2012), the groundwater head has been increasing


Subsidence in the Mississippi River Delta--Important Influences of Valley Filling by Cyclic Deposition, Primary Consolidation Phenomena, and Early Diagenesis
ABSTRACT Late Pleistocene fluvial entrenchment, cyclic deposition during the Holocene rise in sea level, and primary consolidation characteristics of valley-fill facies are key factors in
Sea-Level Rise and Subsidence: Implications for Flooding in New Orleans, Louisiana
Global sea-level rise is projected to acceler­ ate twoto four-fold during the next century, increasing storm surge and shoreline retreat along low-lying, unconsolidated coastal margins. The
Mississippi Delta subsidence primarily caused by compaction of Holocene strata
Coastal subsidence causes sea-level rise, shoreline erosion and wetland loss, which poses a threat to coastal populations. This is especially evident in the Mississippi Delta in the southern United
Long-Term Subsidence and Compaction Rates: A New Model for the Michoud Area, South Louisiana
The stratigraphic record of the Michoud area in eastern New Orleans, Louisiana, was examined to address hypotheses developed from recent geodetic studies, which contend faulting, as opposed to
The dominant processes responsible for subsidence of coastal wetlands in south Louisiana
Wetland loss in coastal areas of Terrebonne and Lafourche Parishes, Louisiana, largely results from two subsurface processes: (1) consolidation of recently deposited Holocene deltaic sediments and
Tide gauge records, water level rise, and subsidence in the Northern Gulf of Mexico
Long-term water level changes in the northern Gulf of Mexico were examined using tide gauge records for this century. Strong coherence exists between the annual mean water changes at Galveston,

Modern uparching of the Gulf Coastal Plain
A broad doming of the Gulf coastal plain between Jackson, Mississippi, and New Orleans, Louisiana is indicated by leveling surveys carried out in 1934, 1959, 1964, and 1969. The progressive arching
