USGS Open-File Report 2006-1195, Surficial Sediment Character of the Louisiana Offshore Continental Shelf Region: a GIS Compilation
Description: The Louisiana coastal zone, comprising the Mississippi River delta plain stretching nearly 400 km from Sabine Pass at the Texas border east to the Chandeleur Islands at the Mississippi border, represents one of North America's most important coastal ecosystems in terms of natural resources, human infrastructure, and cultural heritage. At the same time, this region has the highest rates of coastal erosion and wetland loss in the Nation due to a complex combination of natural processes and anthropogenic actions over the past century. The USGS has actively supported coastal and wetlands geologic research for the past two decades in partnership with universities (e.g., Louisiana State University, University of New Orleans), state agencies (e.g. Louisiana Geological Survey, Louisiana Department of Natural Resources), and private organizations (Williams and others, 1992a,b; Williams and Cichon, 1993; List and others, 1994). These studies have focused on regional-scale mapping of coastal and wetland change and developing a better understanding of the processes that cause coastal erosion and wetlands loss, particularly the rapid deterioration of Louisiana's barrier islands, estuaries, and wetlands environments. With a better understanding of these processes, the ability to model and predict erosion and wetlands loss will improve. More accurate predictions will, in turn, allow for proper management of coastal resources. Improved predictions will also allow for better assessments of the utility of different restoration alternatives.

Research Project
National Assessment of Coastal Change Hazards
Description: The National Assessment of Coastal Change Hazards is a multi-year undertaking to identify and quantify the vulnerability of U.S. shorelines to coastal change hazards such as the effects of severe storms, sea-level rise, and shoreline erosion and retreat. It will continue to improve our understanding of processes that control these hazards, and will allow researchers to determine the probability of coastal change locally, regionally, and nationally. The Assessment will deliver these data and assessment findings about coastal vulnerability to coastal managers, other researchers, and the general public.

Research Project
National Assessment of Shoreline Change Project
Description: Beach erosion is a chronic problem along most open-ocean shores of the United States. As coastal populations continue to grow, and community infrastructures are threatened by erosion, there is increased demand for accurate information regarding past and present shoreline changes. There is also need for a comprehensive analysis of shoreline movement that is regionally consistent. To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is conducting an analysis of historical shoreline changes along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii. A primary goal of this work is to develop standardized methods for mapping and analyzing shoreline movement so that internally consistent updates can periodically be made to record shoreline erosion and accretion.

USGS Open-File Report 2005-1027, An Operational Mean High Water Datum for Determination of Shoreline Position from Topographic Lidar Data, Title Page
Description: .The National Assessment of Coastal Change Hazards Project of the U.S. Geological Survey, Coastal and Marine Geology Program, is using lidar mapping technology to determine shoreline position for the Nation's open ocean coasts with sandy beaches. The lidar mapping provides elevations relative to the NAVD88 fixed vertical datum. The shorelines determined from lidar-derived beach profiles are defined as an operational Mean High Water (MHW) contour, and therefore the elevation of the MHW tidal datum must be known relative to NAVD 88. The elevation of the MHW tidal datum varies relative to NAVD 88 along the coast as a function of the local tide range and mean tide level. National Oceanic and Atmospheric Administration (NOAA) tide station data were studied and compiled to tabulate MHW, Mean Higher High Water, and Mean Tide Level elevations along the East, West, and Gulf Coasts. In all, 136 tide stations were chosen: 93 along the East Coast, 19 along the West Coast, and 24 along the Gulf Coast. Although open coast tide stations were preferable for determining MHW, some stations that were not fully on the open coast were used to fill gaps where few or no open coast stations were available. The East, Gulf, and West coastlines were divided into "MHW Zones". These zones are sections of coast to which one MHW elevation is assigned. This operational MHW elevation, which is the average of MHW from all tide stations in the zone, is the elevation used for all lidar shorelines derived within that zone. Twenty-seven zones were created in all: twenty on the East Coast, three on the Gulf Coast, and four on the West Coast.
