摘要
根据现场调查和室内分析资料,阐述了锦州湾潮汐、波浪、海流和沿岸河流等水文要素特征;计算了锦州湾沿岸河流和外海进入湾内的泥沙量;并对锦州湾含沙量分布变化特征、泥沙洄淤状况进行了分析。
Jinzhou Bay is a shallow,half closed bay on the west coast of Liaodong Bay. The tide in the bay is irregular semi - diurnal type, with duration of rising and falling unequal. The current is rectilinear in the bay except in a small part in the north where it turns to be rotary. The mean velocity is 20-40 cm/s. The wave is dominated by wind in the direction of SSW and wave height is 0. 2 - 0. 7 m. The rivers entering the bay are largely short, seasonal ones. The silt amount brought into the bay by rivers and from deep sea are 7.46 × 10 4 t and 8.22×10 4 t in flood season,and 1.37 ×105t and 2. 019×105 t annually from the rivers and deep sea, which would mean a deposit of 5mm-thick-silt on the bottom of the bay annually. The features of hydraulic factors in the bay are presented in terms of in situ observatory and laboratory data analyses. The variation pattern of the sand distribution and back deposition in the bay is approached.
