Detailed Description

河流形态的分维计算

       1)河长:对于Ω级河流,根据Horton河系定律,可得流域河长为:

                

                     

   0时,Ω→∞,并考虑到d1,则有:

               

   式中,K级河流的平均河长;,分别为河流分枝比、长度比和面积比;Ω为河流的最高级。

         2)河网:河网的形态特征一般用河网密度来表示,它是河网的干支流总长度与流域面积的比值:

                     

   考虑到,D1,则有:

              

   式中,分别为河流分枝比、长度比。
