【摘要】 通过分析,在假定河底含沙量与垂线平均含沙量的比值与垂线平均含沙量的函数关系式基础上,给出了简化的河床变形方程,该方程符合泥沙运动力学的基本理论。通过对新的河床变形方程的探讨,发现一般意义上的恢复饱和系数实际上是一个综合参数,而不再是河底含沙量与垂线平均含沙量的比值,可以取远小于1的值。更多还原

【Abstract】 By assuming that the ratio of the bottom sediment concentration to the depth-averaged concentration is a function of the depth-averaged concentration,a new equation is deduced to express the riverbed deformation.The new equation clearly shows that the recovery saturation coefficient is not the ratio of the bottom concentration to the depth-averaged concentration,but a comprehensive parameter.更多还原
