On the basis of the influential factors which have been analyzed for the Yellow River Estuary and the runoff and sediment into the sea, the ralationship is built between the increment or decrement of the yearly stage at the Lijing station and the factors, namely △H=f(Ja, △L, M,A). The deposition slope Ja, boundary condition coefficient A and Oncoming runoff and sediment condition coefficient M can be obtained according to measured evolution process of the courses and given runoff and sediment in sequence of...

On the basis of the influential factors which have been analyzed for the Yellow River Estuary and the runoff and sediment into the sea, the ralationship is built between the increment or decrement of the yearly stage at the Lijing station and the factors, namely △H=f(Ja, △L, M,A). The deposition slope Ja, boundary condition coefficient A and Oncoming runoff and sediment condition coefficient M can be obtained according to measured evolution process of the courses and given runoff and sediment in sequence of date. The extension length of seaside delta (AL) can be obtained on the basis of the position of the change of course, seaside condition and deposition state as follows:旹rrors between calculating results and measured values, AL are within 10%, standard error S \x\ =78.2m, and standard error of the increment or decrement of stages only 0.009m. The calculating results 'obtaindecl from using the method for the projects of the Lower Yellow River in the near fature 12 years, and after the Construction ^ of Xiao Lang Di Reservoir 50 years show th^t those are qualitatively consistent with the calculating results of other methods, whieh reflect the influences of the*? -estuarial course change and the position of course into the sea, and also giveAthe process of stage change year after year, which associates closely with process in estuarial course.

本文在分析黄河口及其来水来沙等影响因素的基础上,建立了利津站年水位升降值与各因素间的关系,即△H=f(Ja,△L,M,A).依各流路演变过程实测资料和给定的预估水沙系列得到相应各序列年份的淤积比降Ja,水沙条件系数M和边界条件系数A值.滨海区三角洲的延伸状况(△L),依改道部位、海域条件和淤沙状况按下式求得 计算结果与实测值的误差△L在±10%以内,标准误差S|x|=78.2m,水位升降的标准误差仅为0.009m.用此法对黄河下游近期12年和小浪底水库建后50年的预估结果表明,与其他方法计算的结果性质一致,且反映了河口改道和入海部位的影响,并可给出与河口演变密切结合的逐年水位变化过程.

In this paper the authors take two rainstroms occurred in the Nihegou watershed of Chunhua County as an example to discuss the characteristics of rainstorm erosion on the south of loess plateau, and the states of sediment yield and runoff in the Yuan and gully area are analysed.
