COMPARISON OF NUMERICAL METHOD FOR FORWARD AND BACKWARD TIME CENTERED SPACE FOR LONG - TERM SIMULATION OF SHORELINE EVOLUTION

ABSTRACT

Mathematical modeling of shoreline evolution becomes a useful engineering technique for investigating and predicting the evolution of the plan view of the sandy beach. In this paper two numerical schemes for the shoreline evolution in the long-term scale are presented, and comparisons to analytical solution for some cases are presented for a satisfactory level of suitable numerical scheme. Analytical solutions of shoreline evolution for simple configuration are presented under idealized wave condition. Based on the result that backward time centered space scheme more suitable than forward time centered space scheme to simulate shoreline evolution in the long-term scale.
