For the coastal zones of Vietnam, the storm and monsoon waves are considered as the maximum waves for the designed of the marine constructions as sea dyke and other constructions in the coast and in the marine areas. The most challenges are to choose the appropriate storm wave model, to formulate the wind input data set and especially to find the wave data in such utmost dangerous sea state for model validation and for analyzing the forecast results. | Computation of storm and monsoon wave parameters for sea dyke design in Vietnam Nguyen Manh Hung1 Nguyen Khac Nghia2 and Duong Cong Dien1 Abstract For the coastal zones of Vietnam the storm and monsoon waves are considered as the maximum waves for the designed of the marine constructions as sea dyke and other constructions in the coast and in the marine areas. The most challenges are to choose the appropriate storm wave model to formulate the wind input data set and especially to find the wave data in such utmost dangerous sea state for model validation and for analyzing the forecast results. In the report the authors present the results of the wave model validation assessments of the computed wave heights accuracy in the storm and monsoon weather. The wave observation by satellite an optimist source of wave data has been also used. The obtains results are promising for the wave computations for forecasting in general and for the research task of the project Determining the wave heights for sea dyke design along the coastal line from Quang Ninh to Quang Nam in particular. 1. Introduction In the coastal zones of Vietnam the storm and monsoon wave parameters are considered as the extreme ones for the design of sea dyke and the coastal marine constructions. The most challenges are to choose an adequate storm and monsoon wave model to analyze the storm wind data and especially to find the wave data in such utmost dangerous sea state for model validation and for analyzing the forecast results. In the report the authors aim on the different wave data sources for model validation and the results of the model verification on the storm and monsoon weather in the East Sea. 2. The wave data for storm and monsoon wave model calibration and verification Focusing on the most reliable wave data set during the storm and monsoon weather the wave recorded in the weather buoys in the oil platforms and the satellite wave data Topex Poseidon have been used. The wave parameters recorded
