【摘要】 胶州湾是青岛的母亲湾,整个青岛的社会生活、经济发展都与胶州湾有着密不可分的关系。随着经济的发展,对胶州湾的开发变得越来越频繁。纳潮量是评价海湾环境的重要指标,它决定着海湾和外海的水交换强度,对海湾的自净、冲於等都具有重要意义。通过对ADCP湾口走航测流数据的处理,得到胶州湾(薛家岛-团岛断面)和内湾(黄岛-团岛断面)的纳潮量,我们发现在落潮期间,通过走航断面的流量值会有一个抖动。这个抖动是观测计算的误差,还是确实存在的现象,本文通过POM模式进行数值实验,给出了合理的解释。经过对不同分潮数的反复模拟,比较了湾口断面流和水位的观测值、5个分潮和24个分潮的模拟值,发现24个分潮能更准确地模拟出实际的潮汐和潮流情况。给出了连续30天的通过两个断面的流量图,计算了胶州湾纳潮量的模拟值,并对观测值和模拟值进行了对比。通过以上工作,对通过胶州湾口断面的流量和胶州湾的纳潮量有了进一步的认识。并且认识到对于小范围海域,5个分潮仅能大体模拟出潮汐潮流情况,要获得更详细的潮汐潮流情况,还需要更多的分潮。更多还原

【Abstract】 Jiaozhou Bay is the mother bay of Qingdao. It exerts a strong influence on social life and economic development. With the development of economy, Jiaozhou Bay is exploited more and more frequently. Storage capacity of tidal water is an important standard for the evaluation of bay environment and confines the exchange quantity of sea water between bay and out sea. Moreover, it has great significance for purifying bay by itself and rinsing sullage.By disposing the data of ADCP sailing observation in the bay mouth, we get the storage capacity of tidal water of Jiaozhou Bay (Xuajiadao-tuandao transect) and inside bay (Huangdao-tuandao transect). We find that there is a wobble of water flux through the sailing transect in ebb tide. Is the wobble an error of observation and calculation or a real phenomenon? We give a reasonable explanation by numerical experiments with POM model.By repeating model of different number of tides, we compare the observation results, 5 tides model results and 24 tides model results of currents in transects of bay mouth and water depth, and we find that it can model the factual currents and tides better by 24 tides model. We provide the water flux figures of the two transects of continual 30 days, calculate the model value of storage capacity of tidal water of Jiaozhou Bay and compare the observation and model value.With the above work, we get further understanding about water flux through transects of bay mouth and storage capacity of tidal water of Jiaozhou Bay, and realize that for small region of sea it can only model the mainly tides and currents by 5 tides in small region of sea, it needs more tides for more particular tides and currents.更多还原
