Close to the South channel of the Yangtze River estuary, the main channel to transport sediment, the east shore of Nanhui becomes an important position for sediment silting. 摘要南匯東灘緊鄰長(cháng)江口主要排沙通道南槽而成為泥沙沉降的一個(gè)重要部位，為促淤?lài)鷫ㄌ峁┝擞欣臑┑睾蛠?lái)沙條件，是上海市規劃圍墾的重點(diǎn)區域。
The author also demonstrates that the accuracy of measured data of coarse particles near the bed layer will not change the total decrease of incoming sediment to TGR. 最后，論述了來(lái)沙減少對三峽水庫淤積的影響，特別是變動(dòng)回水區在相當長(cháng)的一段時(shí)間，淤積還會(huì )大為緩解。
