恢复饱和系数是研究河床演变的一个重要参数，它的选取至关重要。重点介绍了目前国内关于非均匀沙恢复饱和系数的主要研究方法：一维超饱和输沙法和泥沙运动统计理论法。一维超饱和输沙法是通过对一维河床变形方程进行简化和分析，得到适用于该地区的恢复饱和系数，韩其为等基于泥沙运动统计理论，建立了相应的恢复饱和系数表达式。通过总结归纳2种方法得到的研究成果，分析各家公式的差异及适用范围，考虑恢复饱和系数的影响因素，建立了恢复饱和系数一般通用公式，在工程实践中，考虑各个影响因子，对公式中的参数进行率定即可。

Coefficient of saturation recovery is a very important parameter in fluvial process . This paper focuses on two main methods in domestic:1D super - saturated sediment transport law and sediment movement statistical theory method . By simplifying the 1D bed deformation equations , 1D super-saturated sediment transport method gets recovery saturation coefficient applied to the specific region ;Han Qiwei established a corresponding recovery saturation coefficient expression which was based on sediment movement statistical theory . By summarizing the research results , analyzing differences in various formulas and scope of application , considering restoring saturation factor influencing factors , this paper establishes a general formula for the general coefficient of saturation recovery . In engineering practice , the parameter is calibrated by means of considering the impact of various factors on the formula .
