海州湾西部水动力数值模拟

连云港海域地处海州湾西部,1993年西大堤跨海工程完工后,海域水动力环境已经发生了很大改变。利用2004年7月的实测资料,通过ECOM模式模拟了15 d的水动力场,对潮流、潮能空间分布特性进行了分析,发现西墅以西,临洪河口以南水域流速很小,涨潮流流线沿岸线逆时针流过该水域后,在西墅集水流急,在西墅以东形成一个顺时针的涡,能量很快耗散,西大堤以北海域流速较小;在岬角(如西连岛北,西墅,岚山头以东)附近,高能区与低能区并存,形成外高内低的潮能空间分布,也是整个海州湾在其西部海域消能的体现,低能区分布在中部和西南部水域。

Hydrodynamic Numerical Simulation in Western Part of Haizhou Bay

Lianyungang sea area lies in the west part of Haizhou Bay.Since the long levee was constructed in 1994,the underwater hydrodynamic environment has been influenced greatly.This paper uses ECOM numerical simulation technology to investigate the hydrodynamic environment in this area.Results show that the speed current west of Xishu Port and south of Linhong River is slow and a clockwise whirl is formed east of Xishu after the speedy current flows across anticlockwise,where energy consumes fast.In the north of the levee,the current is slow,and high and low tidal energy sections coexist near the capes during a flood time.That shows that tidal energy is depleted from Haizhou Bay,and the low tidal energy sections exist at the middle and south-west parts of the sea area under discussion.
