    摘要:
    基于非結構網格FVCOM模型構建平潭竹嶼灣潮流泥沙計算模型,開展竹嶼灣附近海域潮汐潮流、懸浮泥沙輸運模擬計算,分析其潮流泥沙的運動特征。模型計算結果顯示,海壇海峽內潮波為前進波,潮流與潮位變化同步,但竹嶼灣內的潮波為駐波;海壇海峽內大潮、小潮期間垂線平均懸浮泥沙濃度差別較;現狀條件下海床的年最大沖刷強度約為10 cm·a-1。實測數據與模擬計算結果的對比研究表明,模型可以較好地模擬竹嶼灣附近潮汐潮流和泥沙的運動特征;竹嶼灣海床總體穩定,可能是周圍工程建設和人工采砂導致竹嶼灣海床局部發生沖淤。
    Abstract:
    An unstructured grid FVCOMbased hydrodynamic model was used to simulate the water level,currents and suspendsediment transport patterns in Zhuyu Bay.The results show that the tidal wave in Haitan Strait maintains the properties of a progressive wave, which means that the tidal current and tide level change synchronously,but the tidal wave in Zhuyu Bay is in the form of a standing wave.The simulation illustrate that the depthaveraged suspended sediment concentration during spring tide and neap tide in Haitan Strait shows litter difference,with the annual maximum erosion intensity standing at about 1.0 cm/a.The comparison between measured data and modeled results shows that the model can simulate the movement characteristics of tidal current and sediment transport in Zhuyu Bay. The comparisons of bathymetry data show that the seabed of Zhuyu Bay is generally stable. Which may suggest that the surrounding engineering construction and sand mining have caused partial erosion and deposition of the seabed of Zhuyu Bay.
