Abstract

Abstract: Wind wave and tidal level are the crucial factors in the design of sea dike project. To balance the engineering cost and engineering safety, an approach was applied to design the combination of wind wave and tidal level with risk consideration. A combined distribution function was built by using Clayton Copula, thereafter, the wind wave and wind level combination risk design model was established. Observed hydrological data on Shenzheng Chiwan area from 1971 to 2002 were analyzed to obtain the combined risk probability of wind wave and tidal level. The results indicate that the probability is low when high wind wave reaching high tidal level, and the model puts the risk probability into consideration, which provides a reasonable method for coastal sea dike design.

Key words: sea dike, design tidal level, design wind wave, risk probability, combination design
