based on the numerical results, characteristics of the tidal system are analyzed in this paper, such as tidal types, tidal elevation, tidal current, vertical structure of tidal current and tidal residuals 根據(jù)數(shù)值模擬結(jié)果,本文分析了渤、黃、東海的潮型分布、潮位系統(tǒng)分布、潮流場的分布、潮流的垂向結(jié)構(gòu)、潮余流等的分布。
further research suggests that waves stir sediments and tidal currents transport the sediments, and waves and tidal current are combined into the dominant dynamic mechanism of coastal erosion, of which tidal residual current takes and transports sediment outward, thus it causes sediment to wane in the coast 進一步結(jié)合波、流動力的對應分析認為,波浪以掀沙為主,潮流以輸沙為主,波浪和潮流的聯(lián)合作用是飛雁灘海岸侵蝕的主要動力機制,其中潮流主要通過馀流攜沙外輸,造成近岸泥沙虧損。
after validating the good agreement between simulated results and observed ones, the characteristics and the distribution rules of tides and tidal currents in the whole seas near to zhejiang are thoroughly analyzed, mainly based on the simulated results, combining with the observed conclusion . the co-tidal and co-range charts, co-current charts, types of tides and tidal currents, distribution of maximum possible tidal range and maximum possible tidal current, phenomenon of diurnal inequality, moving modes of tidal currents, tidal ellipses, distribution of tidal residual currents and the vertical structure of tidal currents and residual currents are investigated respectively . and thereout we draw a series of meaningful conclusions as follows, the main of these are : 1 在驗證模擬與實測符合良好的基礎(chǔ)上,本文以模擬計算結(jié)果為主,結(jié)合實測資料的分析結(jié)論,對整個浙江近海的潮汐、潮流特征和分布規(guī)律作了全面、深入的探討,分別對各主要分潮的潮汐同潮圖、潮流同潮圖、潮汐性質(zhì)、潮流性質(zhì)、最大可能潮差分布、潮汐日不等現(xiàn)象、最大可能流速分布、潮流的運動形式、潮流橢圓、余流分布以及潮流和余流的垂向結(jié)構(gòu)等進行了研究,并由此得到了一系列有意義的結(jié)論。
