Beach Nourishment in the Gulf of Mexico

Attempts to stabilize the shore can greatly influence rates of shoreline change. Beach nourishment in particular will bias rates of observed shoreline change toward accretion or stability, even though the natural beach, in the absence of nourishment, would be eroding. Trembanis and Pilkey (1998) prepared a summary of identifiable beach nourishment projects in the Gulf Coast region that had been conducted before 1996. Those records were used to identify shoreline segments that had been influenced by beach nourishment. Supplemental information regarding beach nourishment was collected from agencies familiar with nourishment projects in the State. All records were compiled to create a GIS layer depicting the spatial...

Sediment Placement, 2012-2015, North and Mid-Atlantic U.S.

There are 6 datasets total that together represent sediment placement in the North and Mid-Atlantic: Proposed Sediment Placement (points, lines, and polygons) and Sediment Placement (points, lines, and polygons).These data are part of a broader project: Inventory of Habitat Modifications to Sandy Oceanfront Beaches in the U.S. Atlantic Coast Breeding Range of the Piping Plover (Charadrius melodus) as of 2015: Maine to North Carolina. An estimate of the length of sandy oceanfront beaches that have received or continue to receive sediment placement from Maine through North Carolina was compiled. Only ocean-facing shorelines or those directly exposed to Long Island Sound or the Peconic Estuary were included in this...

Sediment Placement, Before Hurricane Sandy, North and Mid-Atlantic U.S.

The data are from the Sediment Placement Projects on Sandy Beaches in the U.S. Atlantic Coast Breeding Range of the Piping Plover (Charadrius melodus) prior to Hurricane Sandy.This dataset represents the approximate locations of sediment placement projects along the U.S. North Atlantic coast from Maine through Virginia prior to the time that Hurricane Sandy made landfall in October 2012.The sediment placement projects were identified as part of an inventory of habitat modifications to sandy beach habitat within the U.S. Atlantic Coast breeding range of the federally-threatened piping plover. Sediment placement projects included in the inventory were beach nourishment projects, storm damage reduction projects, beneficial...

Historical Changes in Shoreline in the Gulf of Mexico

There are critical needs for a nationwide compilation of reliable shoreline data. To meet these needs, the USGS has produced a comprehensive database of digital vector shorelines by compiling shoreline positions from pre-existing historical shoreline databases and by generating historical and modern shoreline data. Shorelines are compiled by state and generally correspond to one of four time periods: 1800s, 1920s-1930s, 1970s, and 1998-2002. Each shoreline may represent a compilation of data from one or more sources for one or more dates provided by one or more agencies. Details regarding source are provided in the ‘Data Quality Information’ section of this metadata report. Shoreline vectors derived from historic...

Long Term Shoreline Change Rates

Rates of long-term and short-term shoreline change were generated in a GIS with the Digital Shoreline Analysis System (DSAS) version 2.0, an ArcView extension developed by the USGS in cooperation with TPMC Environmental Services. The extension is designed to efficiently lead a user through the major steps of shoreline change analysis. This extension to ArcView contains three main components that define a baseline, generate orthogonal transects at a user-defined separation along the coast, and calculate rates of change (linear regression, endpoint rate, average of rates, average of endpoints, jackknife).

RTK-dGPS surveys of Lake Michigan beach topography near Ogden Dunes/Burns Harbor, Indiana

The US Army Corps of Engineers (USACE) is evaluating the placement of dredged material in the nearshore areas of Lake Michigan as a means to replenish sand at selected beaches. In order to elucidate the physical processes in the nearshore environment that transport and distribute sand to the beach, the USACE-Chicago District and the US Geological Survey (USGS) developed a plan for a beach replenishment study on Lake Michigan near Burns Harbor/Ogden Dunes, Indiana. In support of this effort, a backpack-mounted Trimble Ag132 RTK-dGPS was used for two surveys of beach topography (August 9, 2016, and October 11, 2016) in the study area.

Upward-profiling ADCP wave and current measurements from Lake Michigan near Ogden Dunes/Burns Harbor, Indiana

The US Army Corps of Engineers (USACE) is evaluating the placement of dredged material in the nearshore areas of Lake Michigan as a means to replenish sand at selected beaches. In order to elucidate the physical processes in the nearshore environment that transport and distribute sand to the beach, the USACE-Chicago District and the US Geological Survey (USGS) developed a plan for a beach nourishment study on Lake Michigan near Burns Harbor/Ogden Dunes, Indiana. In support of this effort, the USGS deployed an upward-profiling acoustic Doppler current profiler (ADCP) to the Burns Harbor/Ogden Dunes study area to collect wave and current data. The ADCP was located at the following World Geodetic System 1984 (WGS84)...

Bathymetric and hydrodynamic surveys of Lake Michigan nearshore near Ogden Dunes/Burns Harbor, Indiana

The US Army Corps of Engineers (USACE) is evaluating the placement of dredged material in the nearshore areas of Lake Michigan as a means to replenish sand at selected beaches. In order to elucidate the physical processes in the nearshore environment that transport and distribute sand to the beach, the USACE-Chicago District and the US Geological Survey (USGS) developed a plan for a beach nourishment study on Lake Michigan near Burns Harbor/Ogden Dunes, Indiana. As part of this plan, the USGS conducted hydrodynamic and bathymetric surveys of the study area before and after placement of dredged material in the nearshore zone. The planned placement of dredge material in the study area occurred between June 15, 2016...
