Wave Prediction for Seawall Rehabilitation in Nanri Island

摘要

The WABED wave model is applied to predict design wave parametersrnfor a seawall rehabilitation project in Nanri Island, Fujian Province,rnChina. By applying P-III curve to analyze the correlated frequency, therndesign deep-water wave parameters at corresponding return periods arernobtained, using measured data from a marine environmental monitoringrnstation during 1962-2000. Wave predictions offer the design parametersrnfor the seawall rehabilitation project, corresponding to the high tide of 1rnin 20 years and the wave height of the same return period. The analysisrnof the field data suggests that the sandy beach in front of the seawallrnshould be protected and the sand mining should be prohibited.
