The records of more than 90 replenished beaches and more than 200 sand-pumping operations on East Coast barrier island shorelines, while fragmentary, reveal a wide range of experiences, with a definite trend towards over-optimism in predicting the cost and performance of replenished beaches. Models and assumptions used to predict the fate of replenished barrier island beaches need careful reevaluation. Until sounder theoretical models are developed, a purely empirical approach is the best for predicting beach behavior.
