Flood Discharge Formula

   Estimation Of Maximum Flood Discharge

• The maximum flood discharge or flow or rate of runoff are calculated with the formulas.

          (1) Ryve's Formula (1884)

                  

                     Q=CM2/3

Where, Q= Maximum Flood discharge

M= Catchment Area

C= Constant

 

         (2)  Dicken's Formula (1865)

Q=CM3/4

Where, Q= Maximum Flood discharge

M= Catchment Area

C= Constant
