THE HIGH FLOOD'S MAXIMUM FLOW ANALYTICAL (RATIONAL) METHOD

 

 

In the Rational Method the high flood's maximum flow is corresponding to an established recurrence interval Tr.

 

Metodo analitico

 

where QT the flow in m³/sec, with:

 

A = flowing surface [Km²];

h = rain's elevation that drops in a period equal to the concentration one [mm];

tc = time of concentration [hours];

c = flowing coefficient;

k = factor that take into consideration the measurement units.
