Salinity_GBI_frontal_SLR: Modeling the effects of large-scale interior headland restoration on tidal hydrodynamics and salinity transport in an open coast, marine-dominant estuary: model input and results

Using version 20.1_19 of the Discontinuous-Galerkin Shallow Water Equations Model (DG-SWEM) (Kubatko and others, 2006), astronomic tides and salinity transport were simulated at Grand Bay, Alabama (AL), under scenarios of interior headland restoration and sea level rise, as described in Passeri and others (2023). The two-dimensional DG-SWEM model can be applied to coastal and estuarine systems to solve for time-dependent hydrodynamic circulation and salinity transport. The DG-SWEM model uses the ADCIRC framework (Luettich and others, 1992) and requires inputs of an unstructured finite element mesh. For this study, the mesh domain has an open ocean boundary in the Gulf of Mexico and has higher spatial resolution elements (20 - 100 meters (m)) along the Mississippi and Alabama coast. The model mesh coordinates (latitude and longitude) and simulated average salinity concentrations are included in this data release. For further information regarding model input generation and visualization of model output, refer to Passeri and others (2023).

Hydrodynamic and sediment transport tsunami models at the Salmon River estuary, Oregon

This portion of the USGS data release describes the Delft3D-FLOW model application for propagating simulated tsunamis from 15 hypothetical earthquake sources of the Cascadia Subduction Zone through a series of nested grids to modeling tsunami sediment transport in the Salmon River estuary, OR. Input files necessary to run the Delft3D-FLOW model are provided.
The model application was constructed using Delft3D-FLOW. Zip files containing model setup data are provided for each of the nested hydrodynamic grids at 1650 m, 400 m, and 50 m horizontal resolution. The fully three-dimensional sediment transport model at about 10 m resolution contains boundary condition files from the nested hydrodynamic grids for each of the earthquake scenarios, as well as bathymetry files reflecting different amounts of coseismic subsidence associated with the earthquake scenarios and adjusted to either Mean Low Water (MLW) hindcast for the 1700 CE earthquake or Mean Higher High Water (MHHW). Each zip file contains an example model run for the DOGAMI L3 earthquake source on each respective grid. These examples can be used as templates to run the other earthquake scenarios that are provided.

Tracklines of multichannel boomer seismic reflection data collected by the U.S. Geological Survey in Vineyard Sound and Buzzards Bay, MA, 2010 (Esri polyline shapefile, Geographic WGS 84, 2010-047-FA_Boomer_tracklines.shp)

These data were collected under a cooperative agreement between the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, Woods Hole Coastal and Marine Science Center (WHCMSC). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of seafloor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters of coastal Massachusetts, primarily in water depths of 2-30 meters. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (https://woodshole.er.usgs.gov/project-pages/coastal_mass/). The data collected in this study area are located in both Buzzards Bay and Vineyard Sound and are primarily in the shallow water areas around the eastern Elizabeth Islands and Martha's Vineyard, Massachusetts. The data include high resolution bathymetry, acoustic-backscatter intensity, sound velocity in water, seismic-reflection profiles, and navigation data. These data were collected during several cruises between 2007 and 2011 onboard the R/V Rafael using the following equipment: an SEA Ltd SwathPlus interferometric sonar (234 kHz), Klein 3000 dual frequency sidescan sonar, a boomer source and Geometrics 8-channel GeoEel streamer, a Knudsen 3200 subbottom profiling system, and 4 GPS antennae.

Archive of Chirp Subbottom Profile Data Collected in June 2018 From Fire Island, New York

Researchers from the U.S. Geological Survey (USGS) conducted a long-term, coastal morphologic-change study at Fire Island, New York, prior to and after Hurricane Sandy impacted the area in October 2012. The Fire Island Coastal System Change project (https://coastal.er.usgs.gov/fire-island/) objectives include understanding the morphologic evolution of the barrier island system on a variety of time scales (months to centuries) and resolving storm-related impacts, post-storm beach response, and recovery. From June 2-16, 2018, scientists from the USGS St. Petersburg Coastal and Marine Science Center conducted geophysical surveys on Fire Island to characterize and quantify spatial variability in the subaerial geology with the goal of subsequently integrating onshore geology with other surf zone and nearshore datasets. This publication serves as an archive of high-resolution subbottom profile images, survey trackline map, navigation files, geographic information system (GIS) data, and formal Federal Geographic Data Committee (FGDC) metadata. Additionally, in April 2016, geophysical and sediment sampling data were collected as part of the Fire Island project. The ground penetrating radar and vibracore datasets are available from Forde and others, 2018; Buster and others, 2018; and Bernier and others, 2018.

MODFLOW-NWT groundwater flow model and GWM-VI optimization code for the Little Plover River Basin in Wisconsin's Central Sand Plain

The Little Plover River groundwater flow model simulates three-dimensional groundwater 
movement in and around Wisconsin’s Little Plover River basin under steady-state and 
transient conditions. The groundwater flow model uses the U.S. Geological Survey’s 
MODFLOW-NWT modeling code.  This model explicitly includes all high-capacity 
wells in the model domain and simulates seasonal variations in recharge and well 
pumping.  The model represents the Little Plover River, and other significant streams 
and drainage ditches in the model domain, as fully connected to the groundwater system, 
computes stream base flow resulting from groundwater discharge, and routes the flow 
along the stream channel.  A separate soil-water-balance (SWB) model was used to 
develop a groundwater recharge array as input for the groundwater flow model.  The 
SWB model uses topography, soils, land use, and climatic data to estimate recharge 
as deep drainage from the soil zone.  The SWB model explicitly includes recharge 
originating as irrigation water, and computes irrigation using techniques similar to 
those used by local irrigation operators.
		
he groundwater flow model was calibrated to monthly stress periods with time steps 
ranging from 1 to 16 days.  The groundwater model was calibrated to water-level and 
streamflow data collected during 2013 and 2014 by adjusting model parameters 
(primarily hydraulic conductivity, storage, and recharge) until the model produced a 
conditionally optimal fit between field observations and model output, subject to 
consistency with previous published geologic studies.  Calibration was performed 
under both steady and transient conditions and used a sophisticated parameter-estimation 
procedure (PEST) for the calibration process and to identify important model parameters.  
With respect to the Little Plover River the two most important parameters are the global 
recharge multiplier and the hydraulic conductivity of the stream bed.  The calibrated model 
produces water level and mass balance results that are consistent with field observations 
and with previous studies of the area. This USGS data release contains all of the input and 
output for the simulations described in the published report which can be found in the main 
directory of this data release.

Drainage areas for stream segments in western San Diego County

Drainage areas (or watersheds) were calculated for each stream segment in the National Hydrography Dataset High Resolution Plus Beta (NHD HR Plus Beta) using non-end junction points and the provided hydrologically enforced Digital Elevation Model (DEM). The DEM was used to create a flow direction raster. The pour points used were determined from junction points at each stream intersection excluding stream ends (i.e. channel heads are not included). Watershed calculations were automated using the ArcGIS "watershed" tool and then edited manually for accuracy. In western San Diego County (non-desert) there were 39,980 drainage areas calculated. The percent impervious in each watershed was calculated using the National Land Cover Dataset 2019 Impervious surface.

Survey lines along which EdgeTech SB-512i chirp seismic-reflection data were collected by the U.S. Geological Survey - St. Petersburg Coastal and Marine Science Center offshore of the Gulf Islands, MS, 2010 (ESRI polyline shapefile, 10cct02_SeismicTrackline.shp)

In 2010, the U.S. Geological Survey in Woods Hole, MA and St. Petersburg, FL, in partnership with the U.S. Army Corps of Engineers, Mobile District conducted geologic mapping to characterize the seafloor and shallow subsurface stratigraphy offshore of the Gulf Islands of Mississippi. The mapping was carried out during two cruises in March, 2010 on the R/V Tommy Munro of Biloxi, MS. Data were acquired with the following equipment: an SEA Ltd SwathPlus interferometric sonar (both 234 kHz and 468 kHz systems), a Klein 3000 and a Klein 3900 dual frequency sidescan-sonar, and an Edgetech 512i chirp subbottom profiling system. The long-term goal of this mapping effort is to produce high-quality, high-resolution geologic maps and geophysical interpretations that can be utilized to identify sand resources within the region and better understand the Holocene evolution and anticipate future changes in this coastal system. More information on the field work can be accessed from the Woods Hole Coastal and Marine Science Center Field Activity webpage https://cmgds.marine.usgs.gov/fan_info.php?fan=2010-012-FA or the St. Petersburg Coastal and Marine Geology InfoBank https://walrus.wr.usgs.gov/infobank/m/m210gm/html/m-2-10-gm.meta.html.
