补充资料:径流特征值
      河川径流特征的统计值。反映河川径流量随时间变化的统计参数。依据自然现象与工程实用要求,河川径流特征一般指各年的年平均流量、各月的月平均流量,一年中最大的洪水流量,一年中最小的枯水流量。
  
  各种径流特征的数值是随时间而变化的,例如,各年的年平均流量都不相同,各年的最大洪水流量也都不相同。概括的反映这种变化基本特点的统计参数有(相应于各种径流特征的)均值,变差系数,偏差系数和各阶自相关系数。均值反映河川径流量总的蕴藏量多寡,变差系数和偏差系数反映各年间径流量变化幅度的大小,各阶(相隔一年为一阶,相隔两年为二阶,余类推)自相关系数反映相邻年份径流量间相互密切程度。
  
  径流量的表示方法很多,常用的有以下几种:一定时段(如年、月、日等)的径流总量,其单位通常为立方米;一定时段的平均流量=一定时段径流总量/时段长度,通常以米3/秒计;一定时段的流域平均径流深=一定时段径流总量/流域面积,通常以毫米计;一定时段的径流系数=一定时段的流域平均径流深/一定时段的流域平均降雨深。有时也把这些计算径流的单位叫径流特征值。
