SEDIMENT BUDGET ESTIMATES FOR SHORELINE PROJECTIONS

This study examines coastal dynamics along the central-southern coast of Rio Grande do Sul (RS), focusing on the interaction between the sediment budget (SB) and sea-level rise (SLR). Using the RanSTM model, the morphological response of the region to SLR was simulated. Calibration employed SB data estimated at different temporal scales: annual (DRONE surveys), decadal (satellite imagery), and long-term (stratigraphy and geophysics).
