What is SBAS? Sediment budgets provide a conceptual and quantitative model of the magnitudes and pathways of sediment transport at inlets and adjacent beaches for a given timeperiod. Sediment budgets give a framework for understanding complex inlet and coastal systems and their responses to coastal engineering projects. Any convenient method, such as a spreadsheet application, can be used to formulate and calculate a sediment budget. SBAS is a convenient method for formulating regional sediment budgets for coastal regions, including inlets, because it is visually based, provides an integrated picture of the processes while archiving detailed calculations within the system, and allows variations in the sediment budget to be rapidly examined.</font></div>
