Relative Sea Level Rise and Delta-plain Development in the Terrebonne Parish Region


Book Description

This report presents the results of an investigation of relative sea level rise and delta-plain development in the Terrebonne Parish region of Louisiana, where rates of land loss and barrier island erosion are currently among the highest in the United States. Data from tide gage stations, geodetic leveling surveys, vibracores, and studies measuring cesium-37 activity in surface cores document a new chronology for the Terrebonne Parish region and reveal that, except immediately adjacent to the Atchafalaya delta complex, the current rates of wetland sedimentation are not sufficient to maintain the coastal marshes against the effects of relative sea level rise and subsidence. Over the next century, relative sea level in this region could rise 0.18-2.80 m, and the entire Terrebonne Parish delta plain faces catastrophic land loss and could not be converted to open water.










Relative Sea Level Rise and Subsidence in Louisiana and the Gulf of Mexico


Book Description

Data from two tide gage networks in Louisiana and the northern Gulf of Mexico were analyzed to determine local and regional trends in relative sea level rise. Eustatic correction factors were applied to the rates of relative sea level rise to determine rates of subsidence. The U.S. Army Corps of Engineers (USACE) maintains a network of 83 tide gage stations throughout coastal Louisiana. Of these, 20 have records adequate to represent our study period (1942-1982), and some date back to 1933. The USACE data set was used to determine the local and regional character of relative sea level rise in Louisiana. The National Ocean Survey (NOS) maintains nine tide gage stations throughout the northern Gulf of Mexico in Texas, Louisiana, Mississippi, Alabama, and Florida. All of these stations have an adequate period of record for this study, and some have records dating back to 1913. We used the NOS data set to determine the character of relative sea level rise and subsidence throughout the entire northern Gulf of Mexico. This investigation is the first systematic regional analysis of these tide gage stations that uses only the long-term water-level records.

The Proceedings of the Coastal Sediments 2011


Book Description

This proceedings contains nearly 200 papers on cutting-edge research presented at the seventh international Symposium on Coastal Engineering and Science of Coastal Sediment Processes, held May 2OCo6, 2011, in Miami, Florida, USA. This technical specialty conference was devoted to promoting an interdisciplinary exchange of state-of-the-art knowledge among researchers in the fields of coastal engineering, geology, oceanography, and related disciplines, with a theme of bringing together theory and practice. Focusing on the physical aspects of sediment processes in various coastal environments, this three-volume conference proceedings provides findings from the latest research and newest engineering applications. Session topics cover a wide range including barrier-island morphodynamics and evolution, beach nourishment and shore protection, coastal dunes, cohesive sediment transport, field and laboratory measurements of sediment transport processes and numerical modeling, gravel transport, large-scale and long-term coastal changes, LiDAR and remote sensing, longshore and cross-shore sediment transport, marsh and wetlands, regional sediment management, river deltas, sea-level changes, shelf and sand bodies, shoreline changes, tidal inlets and navigation channels. A special session on recent research findings at the Northern Gulf of Mexico is also included."

Environmental Hydrogeology


Book Description

Headlines continue to blare news of climate change, tangential catastrophic events, and dwindling energy resources. Written by respected practitioners, and geared to practitioners and students, Environmental Hydrogeology, Second Edition explores the role that hydrogeology can play in solving challenging environmental problems.

Multifunctional Wetlands


Book Description

This book describes how natural or constructed wetlands can be used to reduce pollution of freshwater and coastal ecosystems, while still preserving their biodiversity and ecological functions. Through a series of case histories described in 10 chapters in the monograph, the readers will gain an understanding of the opportunities, as well as the challenges associated with reducing point and non-point source pollution using natural, restored or constructed wetlands. The target audience will be water practitioners involved in projects utilizing integrated watershed management approaches to pollution abatement, as well as researchers who are designing projects focused on this topic.
