Coastal morphological modeling uses three-dimensional models to predict changes in beach and ocean floor shape based on how sediment moves in different directions. These models are more detailed and can analyze local changes accurately, but they take longer to compute. Advances in computer technology have helped reduce the time needed for these calculations. These models can be used to forecast short to medium-term changes in coastal topography. Simplified models based on past trends and local data are useful for understanding general patterns but are not as precise for specific predictions.
