通过对龙门站近几年掀起泥块露出水面再坍塌消失现象的观测分析，进一步认识到：这种现象既不是高含沙、大流量水流的特产，也不是长河段揭河底冲刷的主要现象；１９５４ 年９ 月洪水不属于长河段揭河底冲刷洪水；１９５１ 年以来７ 次长河段揭河底冲刷均未发展到黄淤４９ 断面（ 老永济） ；揭河底冲刷洪水，主要是由吴堡—龙门区间为主的暴雨洪水组成的。解剖各次长河段揭河底冲刷洪水过程的分段冲淤变化性质，较合理地计算了７ 次揭河底冲刷的历时和冲刷深度。
Through the observation and analysis of the disappearance of the mud surface exposed and then collapsed by the Longmen Station in recent years, it is further recognized that this phenomenon is neither a special product of high sediment concentration nor high flow, nor is it the main phenomenon of long-river scouring ; Floods in September 1954 did not belong to the long river reach the bottom of the river scouring floods; since 1951, seven long river reachs did not develop to the Yellow River 49 cross-section (Laoyongji); exposing the river scouring flood was mainly caused by Wu Fort - gantry-based storm flood component. Dissecting the scouring and silting changes in the process of scouring flood at each end of the long reach of the river, the time and scouring depth of 7 scubaphyshes were calculated reasonably.
