Detailed Description

黄河断流变化规律

 

(1)利津站断流天数与花园口站月平均流量的关系式:

N=36.33-0.0215Q

式中,N为利津站断流天数;Q为花园口站月平均流量。

(2)全日断流天数与总断流天数的关系式:

          Nd=-2.5579+0.9328N

式中,Nd为利津站全日断流天数;N为总断流天数。

(3)年最长断流天数与时段数的关系式:

          Nm=8.9299exp(0.4526t)

式中,Nm为年最长断流天数;t为时段数。

(4)累计断流天数与时段数的关系式;

          

式中,N(t)为累计断流天数。

(5)年断流长度与时段数的关系式:

          L=45.4286+95.1429t

式中,L为年断流长度。

(6)最早断流日与时段数:

            DOY=209.12exp(-0.2638t)

式中,DOY为最早断流日。
