The Sediment Budget Analysis System (SBAS) is an ArcGIS toolbox for creating and visualizing sediment budgets. Sediment budgets provide a conceptual and quantitative model of sediment transport magnitudes and pathways for an area over a given time period. Users can define sediment budgets visually by creating littoral cells and fluxes depicting sediment sources into the cell and sediment sinks out of the cells. Transport and volume change rates from literature reviews, field measurements, or other model results are added to this cells and fluxes to quantify change rates. Budgets can be visualized based on areas of erosion/accretion or highlight areas with unaccounted for sediment. Budgets can be published and downloaded from the SBAS Hub viewer.
