The Studies Of Design Wave Elements In Shandong Peninsula Blue And Yellow Zones

Entering the21st century, to adapt itself to the changing situation at homeand abroad, Shandong has staged a series of major strategic to promote economic andsocial development sustainably and swiftly. On November23,2009, the State Councilof China has approved “the Development Planning of the Yellow River DeltaHigh-efficiency Eco-economic Zone”, which implied that the development of theYellow River Delta has risen to national strategy and become an important part ofnational regional harmonious development strategy. On January4,2011, the StateCouncil of China has approved “the development plan for the Shandong PeninsulaBlue Economic Zone” officially, which indicate that the development of the ShandongPeninsula Blue Economic Zone has upgraded into a national strategy, and play ansignificate role in national marine economic development strategy and regionalharmonious development strategy. Shandong peninsula responses to these twonational strategy actively. With its preferable geographical conditions and Portresources, through the way of developing marine transportation, building port systems,speeding up port construction and development of the peninsula, Shandong peninsulacan be an international shipping center in Northeast Asia. As the requirement for portengineering design, the design wave elements is of the vital importance for the harborengineering construction. In this paper, the wind field is selected as driving conditions.Besides, the third generation wave model SWAN is used to simulate East China Seaarea and then acquire its boundary condition which is nested to Shandong Peninsulaarea afterwards. Finally, the design wave elements can be obtained.The used22years (1990-2011) wind field data is calculated by WRFsimulations. After verifying the measured data of two observation points which is alsocomputed in numerical simulation, the fitting result is agreeable. In addition, Thewave height and period data which is obtained from simulative calculation in SWANis validated with the measured data of five observation points. So, the wave elements of the Shandong peninsula can be simulated well in SWAN.Through the simulation calculation, wave elements of Shandong peninsulafrom1990to2011can be gained. For instance, in2010, the wave height distributionof Shandong peninsula from twelve months, four quarters, sixteen direction, as wellas four quarters waves rose of Zhang Jia Bu areas are acquired in calculation. Finally,through applying the wave data of22years integrally,16directions of maximumwave height every year can be extracted respectively. Furthermore, Ao Shan Chaidaois taken as the example. Through the Pearson Ⅲ type distribution, the return periodwave heights of16directions of a-hundred-year return period, fifty year return period,twenty year return period, a decade return period year, five year return period, twoyear return period can be computed respectively.
