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.
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.
