At first, this paper analyzes the factors of water - sand influencing water level of yellow river and the feasibility just using the factors of water - sand to study water level, and collects the corresponding data ; secondly, because there are strong nonlinear relation in the corresponding data, by meticulous theory analysis, this paper integrates basic nonlinear analysis method, theory of random analysis, method of least squares and so on. it puts forward a method which can get the high accuracy simulation of the data, perfects the multi - factor analysis of variable ( over three factors ) of the statistic ; thirdly, it applies the method to the approximation of corresponding water level process which belong to the capacity of sand of middle - high and middle - low, and get the high - accuracy simulation about the typical nonlinear relation ; at last, this paper definitudes the main influence mode that the capacity of sand. it mainly unite with other factors to work on the water level in the yellow river lower reaches ; mor eover, this paper analyzes the difficult point and the direction of improvement to realize the accuracy forecasting of the flood level of erodible - bed channel
首先，系統分析了影響黃河水位的水沙因素，及僅用水沙因素有效研究水位的可行性，並按變量對應思想採集它們的相應數據；其次，由於相應水位過程數據中含極強的非線性關系，本論文經細致的理論分析，將基本的非線性分析方法、統計建模方法、隨機分析理論、最小均方誤差原則等等數學理論及方法有機揉合，提出了能有效實現這類數據高精度擬合的分層篩選法，並改進了統計學中多因子（三個以上）方差分析法；再次，將這一方法用於黃河中高及中低含沙類洪水相應水位過程的擬合，實現了這一典型非線性關系的高精度擬合，各年汛期上下游相應洪水位過程的擬合誤差都較小；最後，明確黃河下游含沙量對水位的主要影響方式，即含沙量主要是與其它因素聯合對水位作用；另外分析了要實現變動河床洪水位過程準確預報的困難所在及改進方向。 -
Fairly utilizing the flood resources of the yellow river can achieve the objectives of " no dyke breaches, no depletion, no pollution exceeding the standards and no rising of the river bed " and keep the healthy life of the river
利用好黃河的洪水資源，可實現「堤防不決口，河道不斷流，污染不超標，河床不抬高」的目標，從而維持黃河的健康生命。 -
Since boundary of the lower yellow river bed varies with the flow conditions, main channel of the stream continually shrank and flood control becomes rather difficult
隨著黃河下游水沙條件的不斷變化，河道的邊界條件也隨之發生變化，主槽嚴重萎縮，泄洪能力日臻下降，防洪問題日益突出。 -
I am worn out from groaning ; all night long i flood my bed with weeping and drench my couch with tears
6我因唉哼而睏乏；我每夜流淚，把床榻漂起，把褥子濕透。 -
There is sharp gradient in top and small gradient in bottom. the ability of removing flood is high in top and it is small in bottom correspondingly. sediment silt up continually, so the bed of river is jacked up year by year and become the famous river on land
由於泥沙含量高，現行河道已行水140餘年，山東段河床上寬下窄，坡度上陡下緩，排洪能力上大下小，在泥沙淤積作用下，河床逐年抬高，成為世界上著名的地上「懸河」 。 -
In the past decade, we built a total of some 31 kilometres of concrete channel bed in 16 major river training and flood prevention projects ( see annex 1 for details )
在過去十年，我們在16項主要河道治理及防洪工程中建造共約31公里混凝土河床，詳見于附表一。 -
The character of flood channel can be determined by dominate current, dominate tidal volume, dominate sediment concentration, channel geometry configuration and direction of bed sediment transport and so on
用優勢流、優勢沙、優勢潮量、漲潮槽形態和凈底沙運移方向的方法都可以表達漲潮槽的性質。 -
Especially for resent years, because the conditions of coming discharge and sediment have occurred un - corresponding variation, shrink ' s velocity increases serious rapidly, shrink ' s characters tend to be serious, the river bed have been heightening continuously, from these, they have lead to various disaster effects obviously and brought heavy pressure for flood control and river harnessing
黃河下遊河道為嚴重的萎縮性河道。尤其是近年來，由於來水來沙條件發生非協調性變異，萎縮速率明顯加快，萎縮性更趨嚴重，河床持續抬高，由此引起的各種災害效應愈加明顯，對防洪及河道治理產生巨大壓力。 -
Self - abandoned, relaxed, and effortless, i seemed to have laid me down in the dried - up bed of a great river ; i heard a flood loosened in remote mountains, and felt the torrent come : to rise i had no will, to flee i had no strength
我自暴自棄，渾身鬆弛，百無聊賴，彷彿躺在一條大河乾枯的河床上，我聽見洪水從遠山奔瀉而來，我感覺到激流逼近了，爬起來吧，我沒有意志，逃走吧，我又沒有力氣。 -
Moreover, attentions must be paid to the tributary with slight slope bed, because the water flowing into the tributary from the main channel during the uprising period of main channel flood may cause large - scale inundate in the tributary basin
研究結果表明：在干支流交匯口，幹流流量變化速率越大，支流倒灌流量越大；幹流洪水陡漲時灌入支流的巨大水量對底坡平緩支流可能造成的淹沒危害應引起充分重視。 -
Finally, by using of the mathematical model, it is calculated and predicted the effect of the different tongguan riverbed elevations as well as the different conditions of incoming water and sediment on the variance of the flood elevation and the tend of aggradation and degradation of the lower weihe river bed. it is answered quantitively the lessening extent of sediment silt and the decreasing extent of the flood elevation of the lower weihe river after 14 years on two different incoming water and sediment conditions with three different tongguan elevations, respectively 328m, 327m and 326m. these results supply important references to the planning of flood control and comprehensive regulations of the weihe river basin
最後用驗證后的數學模型對不同水沙系列、不同潼關高程（ 328m 、 327m 、 326m ）下渭河下游的沖淤趨勢和洪水位的變化進行了預測計算，從定量上回答了潼關高程從328m降至327m （相當于潼關高程降1m ）和潼關高程從328m降至326m （相當于潼關高程降2m ）時，渭河下游14年之後各河段的減淤程度以及不同流量級洪水位的降低幅度，這些成果對于渭河下游防洪治理規劃的制定具有重要的參考價值。
