Dauphin Island Decadal Hindcast Model Inputs and Results Dauphin Island Decadal Hindcast Model Inputs and Results
The model input and output of bathymetry and topography elevations resulting from a deterministic simulation from 2004 to 2015 at Dauphin Island, Alabama, as described in Mickey and others (2020), are provided here. For further information regarding model input generation and visualization of model output topography and bathymetry refer to Mickey and others (2020). For more information...
Storm-Induced Coastal Change Forecasts: Archive of Individual Storm Events Storm-Induced Coastal Change Forecasts: Archive of Individual Storm Events
These data sets contain information on the probabilities of storm-induced erosion (collision, inundation and overwash) on sandy beaches along the U.S. Gulf and Atlantic coasts during real-time peak forecast conditions. The analysis is based on a storm-impact scaling model that uses observations of beach morphology combined with sophisticated hydrodynamic models to predict how the coast...
Mobile Harbor Navigation Channel Delft3D Model Inputs and Results Mobile Harbor Navigation Channel Delft3D Model Inputs and Results
The Delft3D model inputs and outputs of bed levels resulting from the simulations of proposed navigation channel deepening and widening in Mobile Harbor, Alabama, as described in USGS Open-File Report 2018-1123, are provided here. For further information regarding model input generation and visualization of model output elevations, refer to USGS Open-File Report 2018-1123.
Storm-Impact Scenario XBeach Model Inputs and Results Storm-Impact Scenario XBeach Model Inputs and Results
The XBeach model input and output of topography and bathymetry resulting from simulation of storm-impact scenarios at the Chandeleur Islands, LA, as described in USGS Open-File Report 2017-1009 (https://doi.org/10.3133/ofr20171009), are provided here. For further information regarding model input generation and visualization of model output topography and bathymetry refer to USGS Open...
National Assessment of Hurricane-Induced Coastal Erosion Hazards: South Carolina to New Hampshire update National Assessment of Hurricane-Induced Coastal Erosion Hazards: South Carolina to New Hampshire update
These data sets contain information on the probabilities of hurricane-induced erosion (collision, inundation and overwash) for each 1-km section of the U.S. coast for category 1-5 hurricanes. The analysis is based on a storm-impact scaling model that uses observations of beach morphology combined with sophisticated hydrodynamic models to predict how the coast will respond to the direct...
Cape Canaveral, Florida 2010 Single-beam Bathymetry Data Cape Canaveral, Florida 2010 Single-beam Bathymetry Data
Single-beam bathymetric surveys were conducted on July 27-29, 2010 along 37 cross-shore transects offshore from Cape Canaveral, Fla. The transects were spaced 500 m apart in the alongshore direction and each was approximately 5 km long in the cross-shore.

Development of a process-based littoral sediment transport model for Dauphin Island, Alabama Development of a process-based littoral sediment transport model for Dauphin Island, Alabama
Dauphin Island, Alabama, located in the Northern Gulf of Mexico just outside of Mobile Bay, is Alabama’s only barrier island and provides an array of historical, natural, and economic resources. The dynamic island shoreline of Dauphin Island evolved across time scales while constantly acted upon by waves and currents during both storms and calm periods. Reductions in the vulnerability...

Forecasting future beach width- A case study along the Florida Atlantic coast Forecasting future beach width- A case study along the Florida Atlantic coast
Historical cross-shore positions of the shoreline and dune base were used as inputs for a Kalman filter algorithm to forecast the positions of these features in the year 2028. The beach width was also computed as the cross-shore distance between the forecasted 2028 shoreline and dune-base positions. While it does not evaluate the suitability of a nesting beach or identify optimal nesting...

Event and decadal-scale modeling of barrier island restoration designs for decision support Event and decadal-scale modeling of barrier island restoration designs for decision support
An interdisciplinary project team was convened to develop a modeling framework that simulates the potential impacts of storms and sea level-rise to habitat availability at Breton Island, Louisiana (Breton) for existing conditions and potential future restoration designs. The model framework was iteratively developed through evaluation of model results at multiple checkpoints. A...

Comparison of methods for modeling fractional cover using simulated satellite hyperspectral imager spectra Comparison of methods for modeling fractional cover using simulated satellite hyperspectral imager spectra
Remotely sensed data can be used to model the fractional cover of green vegetation (GV), non-photosynthetic vegetation (NPV), and soil in natural and agricultural ecosystems. NPV and soil cover are difficult to estimate accurately since absorption by lignin, cellulose, and other organic molecules cannot be resolved by broadband multispectral data. A new generation of satellite...

Imaging spectroscopy for the detection, assessment and monitoring of natural and anthropogenic hazards Imaging spectroscopy for the detection, assessment and monitoring of natural and anthropogenic hazards
Natural and anthropogenic hazards have the potential to impact all aspects of society including its economy and the environment. Diagnostic data to inform decision-making are critical for hazard management whether for emergency response, routine monitoring or assessments of potential risks. Imaging spectroscopy (IS) has unique contributions to make via the ability to provide some key...

Effects of proposed navigation channel improvements on sediment transport in Mobile Harbor, Alabama Effects of proposed navigation channel improvements on sediment transport in Mobile Harbor, Alabama
A Delft3D model was developed to evaluate the potential effects of proposed navigation channel deepening and widening in Mobile Harbor, Alabama. The model performance was assessed through comparisons of modeled and observed data of water levels, velocities, and bed level changes; the model captured hydrodynamic and sediment transport patterns in the study area with skill. The validated...
