  1. 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. Upon using an artificial neural network ( ann ) a new short - term climate forecast model with the monthly mean rainfall in june in the north of guangxi as predictand is established making empirical orthogonal functions ( eof ) to the 36 predictors ( 15 ssa predictors, 21 500hpa height predictors ) with over 0. 05 significant correlation level of previous 500hpa height and sea surface temperature ( sst ) field, and selecting the high relative principal components, at the same time, a new approach of constructing ann learning matrix is developed. predictive capability between the new model ( principal components ann model ) and linear regression model for the same predictors is discussed based on the independent samples and historical samples
