5year_R3_elevation: Modeling the impacts of sand placement strategies on barrier island evolution in a semi-enclosed bay system: model input and results

Using the Delft3D 4 Suite (Lesser and others, 2004), sediment transport and morphologic change was simulated at Little Dauphin Island, Alabama (AL) for 5-year simulations of restoration alternatives as described in Passeri and others (2025). The two-dimensional Delft3D model can be applied to coastal systems to solve for time-dependent bed level elevations. The Delft3D model setup requires the input of bathymetric elevations at each grid cell. Model inputs and outputs in the form of elevation at each grid cell are provided in this data release. For further information regarding model input generation and visualization of model output, refer to Passeri and others (2025).
