SOLUTION TO THE PROBLEMS ON PONDICHERRY BEACH, INDIA

摘要

In the southeast coast of the Indian peninsula, the Pondicherry beach has been suffering from erosion since the completion of the breakwaters that were constructed in 1990 to a harbor. Resultant accretion in the approach channel to the harbor is another problem. One-line coastal model,Unibest, is run to simulate the morphological changes due to problems-orientated alternatives proposed by the present authors. Financial analysis leads to finalization of the most cost-economical alternative, which is capital nourishment plus sand by-passing.
