通过潮流、波浪和泥沙数学模型，对海庙港区两个平面布置方案的水文条件进行了综合对比分析。通过波浪数模研究发现，在底坡较缓的淤泥或粉沙质海岸，当航道内外水深相差较大时，与航道轴线夹角较小的波浪大部分被折射到航道两侧，而不能进入港内。因此，该向波浪对港内泊稳状况不会产生显著影响。通过泥沙淤积计算发现，将港区口门位置由原-2.2 m处移到-2.8 m处，航道年淤积量将减少16.53万m3。%The numerical models of tidal current, wave and sedimentation was adopted to fully compare and analyze the sedimentation conditions required for two general layout plans of Haimiao harbor. Based on the results of numerical model of wave, it is proved that it is mud or mealy sand coast with gentle bottom slope where the wave forming a small included angle with the axis of channel didn’t enter the harbor, it was refracted to both sides of the channel instead subject to large difference of water depth inside and outside the channel. Consequently, the mooring stabilization inside the harbor would be slightly affected by the above wave. The results of sedimentation calculation showed that annual sedimentation volume of the channel could be decreased by 165,300 m3 provided that the harbor entrance was relocated seaward from -2.2 m to -2.8 m.
