【摘要】 以胶州湾为例,尝试获取胶州湾的三维地形,并利用海湾高、低潮所容纳的海水体积之差计算海湾纳潮量。计算结果表明:胶州湾1992年纳潮量为9.8×108 m3,2005年胶州湾纳潮量为8.9×108 m3,胶州湾纳潮能力下降0.9×108 m3。更多还原

【Abstract】 It is physically sound to compute the tidal prism of a bay by using volume difference between high tide and low tide if a 3D model of the bay is obtained.Herein we take the Jiaozhou Bay as an example and calculate the tidal prism in the bay by using this method.The results show that the tidal prism in the Jiaozhou Bay was 9.8×108 m3 in 1992 and 8.9×108 m3 in 2005,indicating that a decrease of 0.9×108 m3 in the tidal prism occurred in the Jiaozhou Bay from 1992 to 2005.更多还原
