【摘要】 1960年以来,渭河下游河道来水来沙条件和边界条件都发生了较大的变化,河道纵横剖面形态针对这些变化进行了相应的调整,通过分析河相关系、主槽面积、河底高程以及弯曲系数的调整规律,对渭河下游河道的自动调整作用进行了研究。更多还原

【Abstract】 So far as the Lower Weihe River is concerned,the conditions of both the inflow and incoming sediment and the relevant boundary conditions had been changed much since 1960,and longitudinal and transverse profiles had been regulated correspondingly for the changes.Through the analysis on the regulating laws of the fluviomorpbological regime,the main channel area,the bottom elevation and the sinuosity coefficient of the river reach,the auto-regulating function of the channel of the Lower Weihe River is studied herein.更多还原
