creager.sdsu.edu:   Calculation of flood discharge by the Creager formula

Spillway at Tucurui Dam, Brazil, rated at 110,000m3/s, the largest in the world.
Formula:

Q = 46 C A 0.894 A - 0.048

In SI Units (metric):
 Area A in km2;
Discharge Q in m3/s.
In U.S. Customary Units:
 Area A in mi2;
Discharge Q in cfs.
INPUT DATA:

Select:      

Drainage area A :        

OUTPUT:

Flood discharge (C = 100)    Q :   0  

Flood discharge (C = 60)    Q :   0  

Flood discharge (C = 30)    Q :   0
