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
