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(jìn)一步結(jié)合波、流動(dòng)力的對(duì)應(yīng)分析認(rèn)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?jiǎng)恿C(jī)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(yàn)證模擬與實(shí)測(cè)符合良好的基礎(chǔ)上,本文以模擬計(jì)算結(jié)果為主,結(jié)合實(shí)測(cè)資料的分析結(jié)論,對(duì)整個(gè)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(duì)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(yùn)動(dòng)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(jìn)行了研究,并由此得到了一系列有意義的結(jié)論。
