Hydrodynamic and Sediment Transport Model Application for OSAT3 Guidance:  Surf-zone integrated alongshore potential flux for oil-sand balls of varying sizes weighted by probability of wave scenario occurrence

The U.S. Geological Survey has developed a method for estimating the mobility and potential alongshore transport of heavier-than-water sand and oil agglomerates (tarballs or surface residual balls, SRBs).  During the Deepwater Horizon spill, some oil that reached the surf zone of the northern Gulf of Mexico mixed with suspended sediment and sank to form sub-tidal mats. If not removed, these mats can break apart to form SRBs and subsequently re-oil the beach.  A method was developed for estimating SRB mobilization and alongshore movement.  A representative suite of wave conditions was identified from buoy data for April, 2010, until August, 2012, and used to drive a numerical model of the spatially-variant alongshore currents.  Potential mobilization of SRBs was estimated by comparing combined wave- and current-induced shear stress from the model to critical stress values for several sized SRBs. Potential alongshore flux of SRBs was also estimated to identify regions more or less likely to have SRBs deposited under each scenario.  This methodology was developed to explain SRB movement and redistribution in the alongshore, interpret observed re-oiling events, and thus inform re-oiling mitigation efforts.

2017 Georgia through New York USACE NCMP Lidar-Derived Dune Crest, Toe and Shoreline

The storm-induced Coastal Change Hazards component of the National Assessment of Coastal Change Hazards (NACCH) project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. Light detection and ranging (lidar)-derived beach morphologic features such as dune crest, toe and shoreline help define the vulnerability of the beach to storm impacts. This dataset defines the elevation and position of the seaward-most dune crest and toe and the mean high water shoreline derived from the 2017 Atlantic Coast (New York and New Jersey) United States Army Corps of Engineers (USACE) National Coastal Mapping Program (NCMP) topobathymetric (topobathy) lidar survey. Beach width is included and is defined as the distance between the dune toe and shoreline along a cross-shore profile. The beach slope is calculated using this beach width and the elevation of the shoreline and dune toe.

GrandBay_ValidationPeriod_Wave_WaterLevel: Modeling the Effects of Interior Headland Restoration on Estuarine Sediment Transport Processes in a Marine-Dominant Estuary: Delft3D Model Output

The effects of interior headland restoration on estuarine sediment transport processes are assessed through process-based numerical modeling. Three proposed interior headland restoration scenarios in the Grand Bay estuary (Mississippi/Alabama) are modeled using Delft3D (developed by Deltares) to understand impacts on suspended sediment concentrations, bed level morphology and sediment fluxes under present-day conditions and a sea level rise of 0.5 meters (m). Delft3D model output of suspended sediment concentrations (SSC), sediment fluxes, initial and final bed levels, and hydrodynamic data are included in this dataset. Model output from six scenarios (comprised of three restoration (R) alternatives and two sea level (SL) conditions) as forced by 18 climatological wind and wave forcing conditions are included in this data release (Jenkins and others, 2023a). For further information regarding model input generation, set up, and analysis, refer to Jenkins and others (2023b).

Shorelines of the Delmarva South and Southern Virginia coastal region from Wallops Island, Virginia to the Virginia/North Carolina border, used in shoreline change analysis (DelmarvaS_SVA_shorelines.shp)

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate.  Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion.  As a result, there is an increased demand for accurate information regarding past and present shoreline changes.  To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.  
There is no widely accepted standard for analyzing shoreline change.  Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments.  The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast.  The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.

5-meter interferometric bathymetry data collected in 2015 by the U.S. Geological Survey along the Delmarva Peninsula, MD and VA (32-bit GeoTIFF, UTM Zone 18N, WGS 84)

The Delmarva Peninsula is a 220-kilometer-long headland, spit, and barrier island complex that was significantly affected by Hurricane Sandy in the fall of 2012. The U.S. Geological Survey conducted cruises during the summers of 2014 and 2015 to map the inner continental shelf of the Delmarva Peninsula using geophysical and sampling techniques to define the geologic framework that governs coastal system evolution at storm-event and longer timescales. Geophysical data collected during the cruises include swath bathymetric, sidescan sonar, chirp and boomer seismic reflection profiles, grab sample and bottom photograph data. More information about the USGS survey conducted as part of the Hurricane Sandy Response-- Geologic Framework and Coastal Vulnerability Study can be found at the project website or on the WHCMSC Field Activity Web pages: https://woodshole.er.usgs.gov/project-pages/delmarva/, https://cmgds.marine.usgs.gov/fan_info.php?fan=2015-001-FA and https://cmgds.marine.usgs.gov/fan_info.php?fan=2015-001-FA.

PR_Q07.TIF - Puerto Rico U.S. EEZ GLORIA sidescan-sonar data mosaic (7 of 9) (ACEA, 50 m, Clarke1866)

The Puerto Rico U.S. EEZ study area includes the seafloor between the island of Puerto Rico and the Puerto Rico Trench floor and extends west to Mona Canyon and east to the U.S. Virgin Islands. South of the islands, it covers parts of the Muertos Trough and the Venezuelan Basin. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the seafloor. A total of 9 digital mosaics of approximately a 2 degree by 2 degree (or smaller) area with a 50-meter pixel resolution were completed for the Puerto Rico U.S. EEZ.

MODFLOW-NWT groundwater model demonstrating groundwater model calibration with repeat microgravity measurements

A numerical model was developed using MODFLOW-NWT and FloPy to simulate groundwater flow and 
demonstrate a practical method for incorporating repeat microgravity observations (i.e., small changes in 
the acceleration due to Earth’s gravity) as a new type of calibration target for groundwater-flow models. 
The single-layer, 250-m cell size model was kept relatively simple to focus on the value of repeat microgravity 
data in the East Mesa area of the Imperial Valley, in the vicinity of the All American Canal, southeast 
California, USA. The method is demonstrated with repeat microgravity data collected over a 10-year period 
following the lining of the All American Canal with concrete. This lining of the canal resulted in the removal 
of a large source of seepage (recharge) causing groundwater levels, groundwater storage, and gravity all 
to declined considerably. The study area and field data are used to demonstrate a novel forward gravity 
modeling application linked to MODFLOW input and output files. The analysis demonstrates that including 
gravity data, compared to drawdown data alone, improves model parameter identifiability and reduces 
uncertainty in parameter estimates. This USGS data release contains all of the input and output files for the 
simulations described in the associated journal article (https://doi.org/10.1111/gwat.13167).

Airborne geophysical survey: Glacier Bay West

Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field intensity values and location. In surveys such as this one where the data were originally collected in digital form and not digitized from contour maps, the information we provide typically includes latitude, longitude, magnetic anomaly in nanoTeslas, and intermediate values used to derive the magnetic anomaly such as total magnetic field.

Simulated constant-head boundary for the transient ground-water flow model, Death Valley regional ground-water flow system, Nevada and California

This digital data set represents the constant head-boundary used to simulate ground-water inflow or outflow 
at the lateral boundary of the Death Valley regional ground-water flow system (DVRFS) transient model. The 
area simulated by the DVRFS transient ground-water flow model is an approximately 45,000 square-kilometer 
region of southern Nevada and California. The hydraulic heads imposed at the constant-head cells were 
interpolated from a regional potentiometric surface ("Larger Work Citation", Appendix 1). Quantity of ground-
water flow at the constant-head boundary was estimated using water-budget and Darcy calculations ("Larger 
Work Citation", Appendix 2), and was used as observation information during calibration of the DVRFS model 
(Faunt and others, 2004). The DVRFS transient ground-water flow model is one of the most recent in a number 
of regional-scale models developed by the U.S. Geological Survey (USGS) for the U.S. Department of Energy 
(DOE) to support investigations at the Nevada Test Site (NTS) and at Yucca Mountain, Nevada (see "Larger 
Work Citation", Chapter A, page 8).

Processed Continuous Resistivity Profile Collected in the Neuse River, April 19, 2004

The Neuse River Estuary in North Carolina is a broad, V-shaped water body located on the southwestern end of Pamlico Sound. This estuary suffers from severe eutrophication for which several water quality models have recently been developed to aid in the management of nutrient loading to the estuary. In an effort to help constrain model estimates of the fraction of nutrients delivered by direct ground-water discharge, continuous resistivity profile (CRP) measurements were made during the spring of 2004 and 2005. CRP is used to measure electrical resistivity of sediments, a property that is sensitive to difference in salinity of submarine ground water. The 2004 and 2005 surveys used floating resistivity streamers of 100 m and 50 m respectively. The depth penetration of the streamers is approximately 20% of the streamer length which translates to approximately 20-25 m with the 100 m streamer and 12-14 m with the 50 m streamer. These data were processed using AGI's EarthImager 2D software. CRP data enables the mapping of the extent and depth of the fresher ground water within the estuary.
