  1. 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。
  2. The dissertation focus on the main conflict of flow and sediment change, by analyzing the flow and sediment features, and change in rivercourse of typical period in histry, collecting the data of riverbed change. according to the flow and sediment change condition, combining the existed water works, and based on the results of former researches, the study are conducted on the law of flow state change by comparing rivercourse conditions before and after the completion of sanmenxia project, which may provide some idea for flow state change when xiaolangdi project completed and put into operation and some basic clue for the prediction of variation trend of river section from tiexie to shendi, from shendi to tieqiao near zhengzhou, from tieqiao near zhengzhou to dongbatou, from dongbatou to gaocun and so on in the year 2010 and the period 2010 to 2020. the result may provide some reference for flood control of these wangdering river sections, and some guidelines for planning of water projects and arrangement of project sequence

    本課題緊緊抓住小浪底水庫運用后水沙變化這一主要矛盾，通過分析研究以往典型時期的水沙特點和河道演變特點，收集分析河床邊界條件變化資料，小浪底水庫運用后水沙資料變化，結合現有河道整治工程建設情況，總結前人的研究成果，重點研究三門峽水庫運用後下遊河道河勢變化的規律和特點，探索小浪底水庫運用後下遊河勢變化情況，分析預測游蕩性河道鐵謝至神堤、神堤至鄭州鐵橋、鄭州鐵橋至東壩頭、東壩頭至高村等各個河段在2010年， 2010年至2020年期間的河勢變化趨勢，為分析游蕩性河段的防洪形勢，指導河道整治工程建設的規劃和工程安排提供決策參考和依據。
