以一般高潮線反映現代黃河三角洲沖淤演變時,從1976年黃河改道清水溝流路入海到2000年,整個黃洞三角洲凈造陸201 . 5km ~ 2 ,淤積有逐漸變慢的趨勢,甚至出現凈蝕退的年份;刁口河嘴大量蝕退,蝕退速率開始快速,后來逐漸變慢;清水溝河嘴大量淤積,淤積速率開始迅速,后來逐漸變慢,甚至出現凈蝕退;清水溝河嘴南側到支脈溝一段岸線與刁口河嘴以西到灣灣溝一段岸線基本穩定。Multispectral data for bathymetry is often performed in relatively clear shallow waters, up to now, no one use multispectral data for bathymetry in estuary waters of yellow river, where the highest sediment concentration in the world has been observed. in another part of this thesis, multispectral data acquired by landsat - 5 tm and in situ data are used for bathymetry in estuarine waters of yellow river. statistical models based on one band and two bands of tm respectively are developed
利用兩期水深的比對可以揭示黃河水下三角洲的沖淤演變規律,但由於實測水深資料獲取較為困難,因而利用遙感來反演水深是一個重要的選擇,為此,本文在黃河口海現代黃河三角洲沖淤演變規律與遙感應用研究端走取兩個試驗區進行了多光譜遙感水深反演試驗,試驗結果表明,在極高泥沙濃度、較強水動力條件的黃河口海域,用多光譜遙感反演水深是可行的。Sediment begins to choke the channel's opening.
沉積物開始淤塞河道口。On the slow weedy waterway he had floated on his raft coastward over ireland drawn by a haulage rope past beds of reeds, over slime, mud - choked bottles, carrion dogs. athlone, mullingar, moyvalley, i could make a walking tour to see milly by the canal

本文選擇黃河下游兩對相鄰水文站多年水沙資料,藉助多種數學方法尋找其中的非線性擾動項,將隨機數學中分析、邏輯、歸納、演繹、隨機的思考問題方式引入到非線性水文預報中,實現沖淤河道相應水位過程的有效擬合。There are a lot of factors that work on the water level of erodible - bed channel together, each of them varies no role, but is correlative. in the adjacent years or the adjacent flood peak of a floodwater, the conditions of the factors that influence water level are always very different. so, there is a nonlinear relation between water level and the factors influencing it
沖淤河道水位受到很多因素的共同作用,各因素本身的變化沒有規律且互相關聯,相鄰前後年份或同一場洪水的不同洪峰前後,影響水位的水、沙、河道等因素常差別很大,水位與其影響因素之間客觀上是非線性關系。Incipient motion of cohesive silt in the haihe river estuary
