  • The paper analyzes and summarizes the following laws of distinctive sediment yield produced in storm floods of the region based on predecessors ' study : storm is the main dynamic force of erosive sediment yield and storm , flood and sediment exist an inevitable relation ; the flood occurring time is concentrated with high peaks and huge volume , suddenly rising and suddenly falling and has decisive influence to the formation of a major flood peak in the middle yellow river ; the main reasons of concentrated coarse sediment of the river is severe erosive sediment yield , strong sediment transporting capacity and high sediment concentration ; the important influence of frequent or continued storm floods happened in he - long reach especially in coarse sediment concentrated region to the sediment transport of the yellow river and ; along with the increase of harnessing , regional flood trend is becoming smaller but the variation of sediment quantity is not obvious and the reaction of peak discharge and flood runoff of majority tributaries are not sensitive , showing that a general and normal engineering works can not effectively control regional major floods especially the sediment of an extraordinary flood
    摘要在前人研究的基礎(chǔ)上分析總結(jié)了該區(qū)特有的暴雨洪水產(chǎn)沙規(guī)律:暴雨是侵蝕產(chǎn)沙的主要動力,暴雨、洪水、泥沙之間存在著必然的關(guān)系;洪水發(fā)生時間集中,峰高量大,暴漲暴落,對黃河中游大洪峰的形成具有決定性影響;侵蝕產(chǎn)沙強烈而粗泥沙集中,輸沙能力強,洪水含沙量高,是黃河粗泥沙的集中來源地;河龍區(qū)間特別是粗泥沙集中來源區(qū)頻繁或連續(xù)的暴雨洪水對黃河輸沙有重要影響;隨著治理水平的提高,區(qū)域洪水有減小趨勢,但泥沙量變化不明顯,大部分支流的洪峰流量、洪水含水量反應(yīng)不敏感,說明一般規(guī)模和水平的治理工程還不能有效控制區(qū)域大洪水特別是特大洪水的泥沙。
