An earlier investigation (Turner 1997) concluded that most of the coastal wetland loss in Louisiana was caused by the effects of canal dredging, that loss was near zero in the absence of canals, and that land loss had decreased to near zero by the late 1990s. This analysis was based on a 15-min quadrangle (approximately 68,000 ha) scale that is too large to isolate processes responsible for small-scale wetland loss and too small to capture those responsible for large-scale loss. We conducted a… Expand
Spatial and temporal patterns of land loss in the Lower Mississippi River Delta from 1983 to 2016
Abstract The Mississippi Delta in coastal Louisiana has some of the highest rates of land loss in the world. This land-loss crisis might become a global problem because most major deltas are expectedExpand
Causes of hot-spot wetland loss in the Mississippi delta plain
Field surveys and sediment cores were used to estimate marsh erosion and land subsidence at Madison Bay, a well-known wetland loss hot spot in coastal Louisiana. Former marshes of Madison Bay areExpand
Mapping the Geomorphology and Processes of Coastal Land Loss in the Pontchartrain Basin: 1932 to 1990 and 1990 to 2001
Abstract The geomorphology and processes of land loss in the Pontchartrain Basin for the period 1990–2001 are mapped and the results of the classification presented. This data set is compared to anExpand
Coast 2050: A New Approach to Restoration of Louisiana Coastal Wetlands
The loss of Louisiana's coastal wetlands continued at a rate of over 60 km2 per year in the 1990s and continued losses of an additional 1295 km2 are projected by 2050. The rapid rate of land loss isExpand
Constraining rates and trends of historical wetland loss, Mississippi River Delta Plain, south-central Louisiana
The timing, magnitude, and rate of wetland loss were described for five wetland-loss hotspots in the Terrebonne Basin of the Mississippi River delta plain. Land and water areas were mapped for 34Expand
Using ecotechnology to address water quality and wetland habitat loss problems in the Mississippi basin: a hierarchical approach.
Wetlands to promote nitrogen removal, mainly through denitrification but also through burial and plant uptake, offer a sound ecotechnological solution and changes in farming practices and use of wetlands for nitrogen assimilation can reduce nitrogen levels in the River. Expand
Analyzing spatial variability of drivers of coastal wetland loss in the northern Gulf of Mexico using Bayesian multi-level models
ABSTRACT A modeling framework that can quantify the impact of multiple potential drivers on coastal wetland loss while estimating its uncertainties is needed to better conserve and restore theseExpand
Wetland Loss Patterns and Inundation-Productivity Relationships Prognosticate Widespread Salt Marsh Loss for Southern New England
It is suggested that southern New England salt marshes are already experiencing deterioration and fragmentation in response to sea level rise and may not be stable as tidal flooding increases in the future. Expand
A Simplified Analytic Investigation of the Riverside Effects of Sediment Diversions
Abstract : Coastal land loss is a striking reality in many coastal communities. The issue is especially acute in coastal Louisiana. Problems of land loss in coastal Louisiana have been extensivelyExpand
Ecological response of forested wetlands with and without Large-Scale Mississippi River input: Implications for management
Abstract We investigated two adjacent wetlands in the Lake Pontchartrain basin, one of which receives periodic input of Mississippi River water and one which does not, to gain insight into howExpand


Wetland loss in the Northern Gulf of Mexico: Multiple working hypotheses
I examined four hypotheses about causes for the dramatically high coastal wetland losses (0.86% yr−1) in the northern Gulf of Mexico: an extensive dredged canal and spoil bank network, a decline inExpand
Land loss in the Mississippi River Deltaic Plain
ABSTRACT Systematic measurements and comparisons of maps, black-and-white aerial photographs, and color infrared imagery taken at five periods within the interval from 1890-1978 have been used toExpand
Land Loss Rates: Louisiana Coastal Plain
Land loss mapping and rate curve development for 62 Quadrangles in the Mississippi River deltaic and chenier plains shows that land loss rates and trends vary significantly throughout coastalExpand
Louisiana wetland loss: A regional water management approach to the problem
Loss of Louisiana's coastal wetlands has reached catastrophic proportions. The loss rate is approximately 150 km2/yr (100 acres/day) and is increasing exponentially. Total wetland loss since the turnExpand
Effect of hydrologic management on marsh surface sediment deposition in coastal Louisiana
A reduction in sediment deposition indicated that the areas under management in this study are receiving insufficient inorganic sediment deposition to keep pace with sea-level rise. Expand
Direct impacts of outer continental shelf activities on wetland loss in the central Gulf of Mexico
The direct impacts of outer continental shelf (OCS) development on recent wetland loss in the northern Gulf of Mexico were quantified using aerial imagery, field surveys, and literature review. TheExpand
The role of the Mississippi River in wetland loss in southeastern Louisiana, U.S.A.
The suspended load of the Lower Mississippi River has decreased almost 80 percent since 1850. The long-term suspended sediment record can be loosely subdivided into three phases: a historic intervalExpand
Consequences of sea level rise: Implications from the mississippi delta
Abstract Sea level rise is expected to increase worldwide over the coming decades, and its impacts are beginning to be felt in many areas. Two major direct impacts of sea level rise are submergenceExpand
Spoil banks: Effects on a coastal marsh water-level regime
Abstract Above- and below-ground water-level fluctuations were measured in the marshes south of New Orleans, Louisiana, between November 1982 and December 1983. The purpose of the program was toExpand
The decline in the suspended load of the Lower Mississippi River and its influence on adjacent wetlands
Since 1850, there has been an overall decrease in excess of 70 percent in the suspended load transported by the Lower Mississippi River. A decrease of 25 percent between the earliest measurements andExpand
