Projections of shoreline change for California due to 21st century sea-level rise
This dataset contains projections of shoreline change and uncertainty bands across California for future scenarios of sea-level rise (SLR). Projections were made using the Coastal Storm Modeling System - Coastal One-line Assimilated Simulation Tool (CoSMoS-COAST), a numerical model run in an ensemble forced with global-to-local nested wave models and assimilated with satellite-derived shoreline (SDS) observations across the state. Scenarios include 25, 50, 75, 100, 125, 150, 175, 200, 250, 300 and 500 ... |

Satellite-derived shorelines for the U.S. Gulf Coast states of Texas, Louisiana, Mississippi, and Florida for the period 1984-2022, obtained using CoastSat
This dataset contains shoreline positions derived from available Landsat satellite imagery for four states (Texas, Louisiana, Mississippi, and Florida) along the U.S. Gulf coast for the time period 1984 to 2022. An open-source toolbox, CoastSat (Vos and others, 2019a and 2019b), was used to classify coastal Landsat imagery and detect shorelines at the sub-pixel scale. Resulting shorelines are presented in CSV format. Significant uncertainty is associated with the locations of shorelines in extremely dynamic ... |

Dissipative SWASH Profiles for Assessing the Role of Bar Morphology on Wave Runup
In 2023, Conti and others (2024a) ran a series of flume experiments to investigate the effect of moisture content on dune erosion. In this study, the flume setup was used from Conti and others (2024b) to assess the role of offshore sandbar morphology on regulating wave runup at the shoreline and hydrodynamics in the nearshore. A hindcast of the Conti and others (2024a) flume experiment was performed using the Simulating Waves Till Shore (SWASH; Zijlema and others, 2011). A series of synthetic flume ... |
