    研究認為： （ 1 ）黃河河口口門逕流潮汐區域並非持續保持淤積狀態，在特定的來水來沙、邊界條件和海洋動力條件下，該區域可以處于沖刷狀態； （ 2 ）從河口泥沙沉積分配的過程來看：三角洲與濱海區泥沙的沉積變化趨勢是基本一致的，各部位的泥沙沉積比例變化基本呈波動狀態，且三角洲與濱海區泥沙的沉積比例與來沙量密切相關，基本成正比關系； （ 3 ）在口門處，影響泥沙沉淤的因素主要集中在潮汐頂托、口門逐漸加寬、河口門分汊、鹽水造成絮凝等，本報告主要對口門加寬，口門西妥理工大學工程碩士專業學位論文分漢對河道淤積的影響進行了定量分析: （一扣根據實測資料首次建立了河贖流路泥沙沉積分配的回歸計算式，據此可以預估計算河口不同區域泥沙的沉淤量; 、 5 ）本項研究首次論證了河口三角洲岸線動態平衡的概念，並建立了黃河河口來沙量與造陸面積的相關關系，得出了當河口多年平均來沙量維持在3 . 45億t時其河口三角洲岸線則可能處于動態平衡狀態的重要結論; 『 6 ）本項研究首次提出了河口泥沙優化調控的概念，並對其宏觀優化調控模式進行了初步探討。
  2. Firstly, we account for the former made and the sand selected are reasonable by experiments. then we develop the first project carrying the experiment for filling up of 30 years. contrasted with the count, the results have no difference, we carried two experiments under different water levers by the actually facts if engineering work in early days. by the result, we know that the gross of fill up have no difference

    本文從白石水庫泥沙模型試驗入手，模型試驗首先通過模型糙率和模型選沙驗證試驗，說明模型製作和選沙是合理的；然後開展初設方案30年運用水庫淤積試驗，並與數模計算對比，基本相同；試驗結合工程初期運用實際情況，進行了兩個不同初期運用水位方案的對比試驗，從兩個方案試驗結果看，初期運用的兩個方案淤積總量差別不大，而從效益看，方案二優于方案一。

  4. The analyzed results are as follows : the late 1960 ' s cutoff of riverbends increased both the runoff amount and the sediment transport amount of the lower reach of jingjiang river, while the sediment deposition decreased in the lkngting lake area ; after the mid 1980 ' s, both the middle reach of yangtze river main stem and the dongting lake occurred a trend of decreasing annual sediment transport as a result of decreasing sediment releasing from the upper reach of yangtze river ; and in the recent 3 years ( 2003 - 2006 ), the three gorges reservoir first impoundment additionally reduced the sediment concentration in the middle reach of yangtze river flow with a long time, so a distance would be quite long for suspended sediment recovery, but the distance for bed - material load of suspended sediment recovery would be quite short

    分析結果表明： 20世紀60年代下荊江裁彎后，三口（松滋口、太平口、藕池口）分流分沙減少，下荊江徑流量和輸沙量相應增加，洞庭湖泥沙淤積減少； 80年代中期以後，長江中游幹流及洞庭湖出口的年輸沙量呈減少趨勢，城陵磯至武漢河段河床由淤積轉為趨向沖淤平衡；三峽工程初期蓄水運用后，長江中游含沙量沿程恢復距離較長，但床沙質部分恢復距離相對較短。
  5.
