  1. Yellow river estuary is typical weak tide and high sediment deposition estuary, the yellow river sediment transport and settling deposition process is the capital factor to determine estuary evolvement characteristics. any method provided for estuary management, there is no exception to have tight relationship with estuary sediment transport and settling deposition process. this paper summarized the yellow river estuary basic characteristics firstly, point out existing problem in this research domain

    黃河河口系典型的弱潮多沙堆積性河口，黃河河口泥沙的輸移擴散和沉積過程是決定河口演變發展特徵的首要因素，黃河河口任何一項治理措施的提出，無一例外均與河口泥沙的輸移和沉積分佈狀況存在密切關系本文首先對黃河河口的基本特性進行了概括總結，在簡略回顧黃河河口泥沙輸移與沉積的有關研究成果的基礎上，指出了當前在此研究領域內存在的問題。
  2. Study achievement appears as following aspects : ( 1 ) yellow river estuary gate river flow and tide flow mixed area is not keep standing deposition status, on special income water and sediment conditions, boundary conditions and oceanic power conditions, this area may on the scour status ; ( 2 ) observed from estuary sediment deposition distributing process : delta and sea offing area sediment deposition vary trend is similar, each part sediment deposition scale varies as wave shape ; ( 3 ) on estuary gate, affect the sediment deposition factors, primary factors are tide prop, the gate widens gradually, estuary gate have branches, brine induced flocculation. this paper study the estuary gate widen, estuary gate have branches to affect the river channel deposition in quantity ; ( 4 ) based on field measured data, for the first time, deduce the estuary sediment deposition and distributing regress formula which can estimate estuary different areas sediment deposition volume ; ( 5 ) this subject demonstrate the estuary delta coastline dynamic balance conception, build the relationship between the estuary income sediment with deposition land area, draw the following important conclusion : when estuary years - averaged income sediment keeps at 345 million tons, the delta coastline may on the dynamic balance status. ( 6 ) this subject firstly brings up estuary sediment optimized control conception, and has the primary study on the macroscopically optimized control conception method

    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。
  3. Analyze the yellow river estuary sediment transport and distributing affected factors, utilize the field measured data, based on the hydraulics, river hydrodynamic and statistics fundamental theory, analyze the estuary sediment transport and settling deposition regulation, yellow river estuary gate area sediment deposition mechanism and estuary delta coastline dynamic balance, and some important achievements acquired

    研究報告分析了黃河河口泥沙輸移和分佈的影響因素，利用實測資料，運用水力學、河流動力學、統計學等基本理論和原理，對河口泥沙輸移及其分佈規律、黃河河口口門區域泥沙沉積機理以及河口三角洲岸線的動態平衡問題進行了分析探討，並取得了部分重要認識和進展。
